Nobel laureates 1905: Philipp Lenard, Adolf von Baeyer, Robert Koch, Henryk Sienkiewicz, Bertha von Suttner

The Nobel Prizes (Swedish: Nobelpriset, Norwegian: Nobelprisen) are prizes awarded annually by the Royal Swedish Academy of Sciences, the Swedish Academy, the Karolinska Institutet, and the Norwegian Nobel Committee to individuals and organizations who make outstanding contributions in the fields of chemistry, physics, literature, peace, and physiology or medicine. They were established by the 1895 will of Alfred Nobel, which dictates that the awards should be administered by the Nobel Foundation. The Nobel Memorial Prize in Economic Sciences was established in 1968 by the Sveriges Riksbank, the central bank of Sweden, for contributions to the field of economics. Each recipient, or "laureate", receives a gold medal, a diploma, and a sum of money, which is decided annually by the Nobel Foundation

Here is a list of 1905 Nobel laureates  

Physics: Philipp Lenard, Slovak-German physicist and academic

Philipp Eduard Anton von Lenard (7 June 1862– 20 May 1947) was a Hungarian-born German physicist and the winner of the Nobel Prize for Physics in 1905 for his work on cathode rays and the discovery of many of their properties. One of his most important contributions was the experimental realization of the photoelectric effect. He discovered that the energy (speed) of the electrons ejected from a cathode depends only on the wavelength, and not the intensity, of the incident light.

Lenard was a nationalist and anti-Semite; as an active proponent of the Nazi ideology, he supported Adolf Hitler in the 1920s and was an important role model for the "Deutsche Physik" movement during the Nazi period. Notably, he labeled Albert Einstein's contributions to science as "Jewish physics".

As a physicist, Lenard's major contributions were in the study of cathode rays, which he began in 1888. Prior to his work, cathode rays were produced in primitive, partially evacuated glass tubes that had metallic electrodes in them, across which a high voltage could be placed. Cathode rays were difficult to study using this arrangement, because they were inside sealed glass tubes, difficult to access, and because the rays were in the presence of air molecules. Lenard overcame these problems by devising a method of making small metallic windows in the glass that were thick enough to be able to withstand the pressure differences, but thin enough to allow passage of the rays. Having made a window for the rays, he could pass them out into the laboratory, or, alternatively, into another chamber that was completely evacuated. These windows have come to be known as Lenard windows. He was able to conveniently detect the rays and measure their intensity by means of paper sheets coated with phosphorescent materials.

Lenard observed that the absorption of cathode rays was, to first order, proportional to the density of the material they were made to pass through. This appeared to contradict the idea that they were some sort of electromagnetic radiation. He also showed that the rays could pass through some inches of air of a normal density, and appeared to be scattered by it, implying that they must be particles that were even smaller than the molecules in air. He confirmed some of J. J. Thomson's work, which eventually arrived at the understanding that cathode rays were streams of negatively charged energetic particles. He called them quanta of electricity or for short quanta, after Helmholtz, while Thomson proposed the name corpuscles, but eventually electrons became the everyday term. In conjunction with his and other earlier experiments on the absorption of the rays in metals, the general realization that electrons were constituent parts of the atom enabled Lenard to claim correctly that for the most part atoms consist of empty space. He proposed that every atom consists of empty space and electrically neutral corpuscules called "dynamids", each consisting of an electron and an equal positive charge.

As a result of his Crookes tube investigations, he showed that the rays produced by irradiating metals in a vacuum with ultraviolet light were similar in many respects to cathode rays. His most important observations were that the energy of the rays was independent of the light intensity, but was greater for shorter wavelengths of light.

These latter observations were explained by Albert Einstein as a quantum effect. This theory predicted that the plot of the cathode ray energy versus the frequency would be a straight line with a slope equal to Planck's constant, h. This was shown to be the case some years later. The photo-electric quantum theory was the work cited when Einstein was awarded the Nobel Prize in Physics in 1921. Suspicious of the general adulation of Einstein, Lenard became a prominent skeptic of relativity and of Einstein's theories generally; he did not, however, dispute Einstein's explanation of the photoelectric effect. Lenard grew extremely resentful of the credit accorded to Wilhelm Röntgen, who received the first Nobel Prize in physics in 1901, for the discovery of the X-ray, despite the fact that Röntgen was German and a non-Jew. Lenard wrote that he, not Roentgen, was the “mother of the X-rays,” since he had invented the apparatus used to produce them. Lenard likened Röntgen’s role to that of a “midwife” who merely assists with the birth.

Lenard received the 1905 Nobel Prize for Physics in recognition of this work.

Chemistry: Adolf von Baeyer, German chemist and academic

Johann Friedrich Wilhelm Adolf von Baeyer (31 October 1835 – 20 August 1917) was a German chemist who synthesized indigo and developed a nomenclature for cyclic compounds (that was subsequently extended and adopted as part of the IUPAC organic nomenclature). He was ennobled in the Kingdom of Bavaria in 1885 and was the 1905 recipient of the Nobel Prize in Chemistry.

Baeyer charted his own path into science early on, performing experiments on plant nutrition at his paternal grandfather's Müggelsheim farm as a boy; back in the confines of Berlin, he took to the test tubes with chemical experimentation starting at the age of nine. Three years later, he synthesized a previously unknown chemical compound -double carbonate of copper and sodium. On his 13th birthday, he initiated his lifework, buying a chunk of indigo worth two Thalers for his first dye experiments.

When still a schoolboy, his chemistry teacher at the Friedrich Wilhelm Gymnasium appointed him as his assistant. After graduating from secondary school in 1853, he entered the Berlin University to study physics and mathematics. A stint in the Prussian army interrupted his study until 1856, when he returned to academia at the University of Heidelberg, intending to study chemistry under Robert Bunsen. After an argument with the renowned chemist, however, he changed his mentor to August Kekulé. He continued to collaborate with Kekule even after he returned to Berlin in 1858 for the completion of his doctorate on arsenic methyl chloride, or cacodylic chloride.

After completing his doctorate, he followed Kekulé to the University of Ghent, when Kekulé became professor there. He became a lecturer at the Berlin Gewerbeinstitut (Royal Trade Academy [de]) in 1860 and a Professor at the University of Strasbourg in 1871. In 1875, he succeeded Justus von Liebig as Chemistry Professor at the University of Munich.

Baeyer's chief achievements include the synthesis and description of the plant dye indigo, the discovery of the phthalein dyes, and the investigation of polyacetylenes, oxonium salts, nitroso compounds (1869) and uric acid derivatives (1860 and onwards) (including the discovery of barbituric acid (1864), the parent compound of the barbiturates). He was the first to propose the correct formula for indole in 1869, after publishing the first synthesis three years earlier. His contributions to theoretical chemistry include the 'strain' (Spannung) theory of triple bonds and strain theory in small carbon rings.

In 1871 he discovered the synthesis of phenolphthalein by condensation of phthalic anhydride with two equivalents of phenol under acidic conditions (hence the name). That same year he was the first to obtain synthetic fluorescein, a fluorophore pigment which is similar to naturally occurring pyoverdin that is synthesized by microorganisms (e.g., by some fluorescent strains of Pseudomonas). Baeyer named his finding "resorcinphthalein" as he had synthesized it from phthalic anhydride and resorcinol. The term fluorescein would not start to be used until 1878.

In 1872 he experimented with phenol and formaldehyde; the resinous product was a precursor for Leo Baekeland's later commercialization of Bakelite.

In 1881 the Royal Society of London awarded Baeyer the Davy Medal for his work with indigo. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1884. In 1905 he was awarded the Nobel Prize in Chemistry "in recognition of his services in the advancement of organic chemistry and the chemical industry, through his work on organic dyes and hydroaromatic compounds", and he continued in full active work as one of the best-known teachers in the world of organic chemistry up to within a year of his death.

Physiology or Medicine: Robert Koch, German physician and microbiologist

Heinrich Hermann Robert Koch (11 December 1843 – 27 May 1910) was a German physician and microbiologist. As one of the main founders of modern bacteriology, he identified the specific causative agents of tuberculosis, cholera, and anthrax and gave experimental support for the concept of infectious disease, which included experiments on humans and other animals. Koch created and improved laboratory technologies and techniques in the field of microbiology, and made key discoveries in public health. His research led to the creation of Koch's postulates, a series of four generalized principles linking specific microorganisms to specific diseases that remain today the "gold standard" in medical microbiology.

During his time as the government advisor with the Imperial Department of Health in Berlin in the 1880s, Robert Koch became interested in tuberculosis research. At the time, it was widely believed that tuberculosis was an inherited disease. However, Koch was convinced that the disease was caused by a bacterium and was infectious, and tested his four postulates using guinea pigs. Through these experiments, he found that his experiments with tuberculosis satisfied all four of his postulates. In 1882, he published his findings on tuberculosis, in which he reported the causative agent of the disease to be the slow-growing Mycobacterium tuberculosis.

For his research on tuberculosis, Koch received the Nobel Prize in Physiology or Medicine in 1905. The Robert Koch Institute is named in his honor.

Literature: Henryk Sienkiewicz, Polish journalist and author

Henryk Adam Aleksander Pius Sienkiewicz (5 May 1846 – 15 November 1916), also known by the pseudonym Litwos, was a Polish journalist, novelist and Nobel Prize laureate. He is best remembered for his historical novels, especially for his internationally known best-seller Quo Vadis (1896).

Born into an impoverished Polish noble family in Russian-ruled Congress Poland, in the late 1860s he began publishing journalistic and literary pieces. In the late 1870s he traveled to the United States, sending back travel essays that won him popularity with Polish readers. In the 1880s he began serializing novels that further increased his popularity. He soon became one of the most popular Polish writers of the turn of the 19th and 20th centuries, and numerous translations gained him international renown, culminating in his receipt of the 1905 Nobel Prize in Literature for his "outstanding merits as an epic writer."

Many of his novels remain in print. In Poland he is best known for his "Trilogy" of historical novels – With Fire and Sword, The Deluge, and Sir Michael – set in the 17th-century Polish–Lithuanian Commonwealth; internationally he is best known for Quo Vadis, set in Nero's Rome. The Trilogy and Quo Vadis have been filmed, the latter several times, with Hollywood's 1951 version receiving the most international recognition.

Peace: Bertha von Suttner, Austrian journalist and author, Nobel Prize laureate (b. 1843)

Bertha Felicitas Sophie Freifrau von Suttner (9 June 1843 – 21 June 1914) was an Austrian-Bohemian pacifist and novelist. In 1905, she became the second female Nobel laureate (after Marie Curie in 1903), the first woman to be awarded the Nobel Peace Prize, and the first Austrian laureate.

In 1889 Suttner became a leading figure in the peace movement with the publication of her pacifist novel, Die Waffen nieder! (Lay Down Your Arms!), which made her one of the leading figures of the Austrian peace movement. The book was published in 37 editions and translated into 12 languages. She witnessed the foundation of the Inter-Parliamentary Union and called for the establishment of the Austrian Gesellschaft der Friedensfreunde pacifist organisation in an 1891 Neue Freie Presse editorial. Suttner became chairwoman and also founded the German Peace Society the next year. She became known internationally as the editor of the international pacifist journal Die Waffen nieder!, named after her book, from 1892 to 1899. In 1897 she presented Emperor Franz Joseph I of Austria with a list of signatures urging the establishment of an International Court of Justice and took part in the First Hague Convention in 1899 with the help of Theodor Herzl, who paid for her trip as a correspondent of the Zionist newspaper, Die Welt.

Upon her husband's death in 1902, Suttner had to sell Harmannsdorf Castle and moved back to Vienna. In 1904 she addressed the International Congress of Women in Berlin and for seven months travelled around the United States, attending a universal peace congress in Boston and meeting President Theodore Roosevelt.

Though her personal contact with Alfred Nobel had been brief, she corresponded with him until his death in 1896, and it is believed that she was a major influence on his decision to include a peace prize among those prizes provided in his will, which she was awarded in the fifth term on 10 December 1905. The presentation took place on 18 April 1906 in Kristiania.

Nobel laureates 1902: Lorentz, Zeeman, Fischer, Ross, Mommsen, Ducommun, Gobat

 The Nobel Prizes (Swedish: Nobelpriset, Norwegian: Nobelprisen) are prizes awarded annually by the Royal Swedish Academy of Sciences, the Swedish Academy, the Karolinska Institutet, and the Norwegian Nobel Committee to individuals and organizations who make outstanding contributions in the fields of chemistry, physics, literature, peace, and physiology or medicine. They were established by the 1895 will of Alfred Nobel, which dictates that the awards should be administered by the Nobel Foundation. The Nobel Memorial Prize in Economic Sciences was established in 1968 by the Sveriges Riksbank, the central bank of Sweden, for contributions to the field of economics. Each recipient, or "laureate", receives a gold medal, a diploma, and a sum of money, which is decided annually by the Nobel Foundation

Here is a list of 1902 Nobel laureates  

Physics: Hendrik Lorentz, Dutch physicist and academic

Hendrik Antoon Lorentz (18 July 1853 – 4 February 1928) was a Dutch physicist who shared the 1902 Nobel Prize in Physics with Pieter Zeeman for the discovery and theoretical explanation of the Zeeman effect. He also derived the transformation equations underpinning Albert Einstein's special theory of relativity.

According to the biography published by the Nobel Foundation, "It may well be said that Lorentz was regarded by all theoretical physicists as the world's leading spirit, who completed what was left unfinished by his predecessors and prepared the ground for the fruitful reception of the new ideas based on the quantum theory." He received many other honors and distinctions, including a term as chairman of the International Committee on Intellectual Cooperation, the forerunner of UNESCO, between 1925 and 1928.

Physics: Pieter Zeeman, Dutch physicist and academic

Pieter Zeeman (25 May 1865 – 9 October 1943) was a Dutch physicist who shared the 1902 Nobel Prize in Physics with Hendrik Lorentz for his discovery of the Zeeman effect

After Zeeman passed the qualification exams in 1885, he studied physics at the University of Leiden under Kamerlingh Onnes and Hendrik Lorentz. In 1890, even before finishing his thesis, he became Lorentz's assistant. This allowed him to participate in a research programme on the Kerr effect. In 1893 he submitted his doctoral thesis on the Kerr effect, the reflection of polarized light on a magnetized surface. After obtaining his doctorate he went for half a year to Friedrich Kohlrausch's institute in Strasbourg. In 1895, after returning from Strasbourg, Zeeman became Privatdozent in mathematics and physics in Leiden. The same year he married Johanna Elisabeth Lebret (1873–1962); they had three daughters and one son.

In 1896, shortly before moving from Leiden to Amsterdam, he measured the splitting of spectral lines by a strong magnetic field, a discovery now known as the Zeeman effect, for which he won the 1902 Nobel Prize in Physics. This research involved an investigation of the effect of magnetic fields on a light source. He discovered that a spectral line is split into several components in the presence of a magnetic field. Lorentz first heard about Zeeman's observations on Saturday 31 October 1896 at the meeting of the Royal Netherlands Academy of Arts and Sciences in Amsterdam, where these results were communicated by Kamerlingh Onnes. The next Monday, Lorentz called Zeeman into his office and presented him with an explanation of his observations, based on Lorentz's theory of electromagnetic radiation.

The importance of Zeeman's discovery soon became apparent. It confirmed Lorentz's prediction about the polarization of light emitted in the presence of a magnetic field. Thanks to Zeeman's work it became clear that the oscillating particles that according to Lorentz were the source of light emission were negatively charged, and were a thousandfold lighter than the hydrogen atom. This conclusion was reached well before J. J. Thomson's discovery of the electron. The Zeeman effect thus became an important tool for elucidating the structure of the atom.

In 1898 Zeeman was elected to membership of the Royal Netherlands Academy of Arts and Sciences in Amsterdam, and he served as its secretary from 1912 to 1920. He won the Henry Draper Medal in 1921, and several other awards and Honorary degrees. Zeeman was elected a Foreign member of the Royal Society (ForMemRS) in 1921. He retired as a professor in 1935.

Zeeman died on 9 October 1943 in Amsterdam, and was buried in Haarlem.

Chemistry: Hermann Emil Fischer, German chemist and academic

Hermann Emil Louis Fischer (9 October 1852 – 15 July 1919) was a German chemist and 1902 recipient of the Nobel Prize in Chemistry. He discovered the Fischer esterification. He also developed the Fischer projection, a symbolic way of drawing asymmetric carbon atoms. He also hypothesized lock and key mechanism of enzyme action. He never used his first given name, and was known throughout his life simply as Emil Fischer.

In 1875, the year following his engagement with von Baeyer, he published his discovery of the organic derivatives of a new compound of hydrogen and nitrogen, hydrazine. He investigated their derivatives, establishing their relation to the diazo compounds, and he noted the readiness with which they entered into combination with other substances, giving origin to a wealth of hitherto unknown compounds. Of such condensation products undoubtedly the most important are the hydrazones, which result from the interaction with aldehydes and ketones. His observations, published in 1886, that such hydrazones, by treatment with hydrochloric acid or zinc chloride, yielded derivatives of indole, the parent substance of indigo, were a confirmation of the views advanced by von Baeyer on the subject of indigo and the many substances related to it.

He next turned to the fuchsine (then called "rosaniline") magenta dyes, and in collaboration with his cousin Otto Fischer, he published papers in 1878 and 1879 which established that these dyes were derivatives of triphenylmethane. Emil Fischer's next research was concerned with compounds related to uric acid. Here the ground had been broken by von Baeyer, but Fischer greatly advanced the field of knowledge of the purines. In 1881 and 1882 he published papers which established the formulae of uric acid, xanthine, caffeine (achieving the first synthesis), theobromine and some other compounds of this group. After purine itself was isolated, a variety of derivatives were prepared, some of which were patented in view of possible therapeutical applications.

Fischer is particularly noted for his work on sugars. Among his early discoveries related to hydrazine was that phenylhydrazine reacted with sugars to form substances which he named osazones, and which, being highly crystalline and readily formed, served to identify such carbohydrates more definitely than had been previously possible. Later, among other work, he is noted for the organic synthesis of D-(+)-glucose. He showed how to deduce the formulae of the 16 stereoisomeric glucoses, and prepared several stereoisomerides, helping to confirm the Le Bel–Van 't Hoff rule of the asymmetric carbon atom.

In the field of enzymology, Fischer is known for his proposal of "the lock and key" model as a mechanism of substrate binding.

Fischer was also instrumental in the discovery of barbiturates, a class of sedative drugs used for insomnia, epilepsy, anxiety, and anesthesia. Along with the physician Josef von Mering, he helped to launch the first barbiturate sedative, barbital, in 1904. He next carried out pioneering work on proteins. By the introduction of new methods, he succeeded in breaking down the complex albumins into amino acids and other nitrogenous compounds, the constitutions of most of which were known, and by bringing about the recombination of these units, he prepared synthetic peptides which approximated to the natural products. His researches made from 1899 to 1906 were published in 1907 with the title Untersuchungen über Aminosauren, Polypeptides und Proteine.

In 1897 he put forward the idea to create the International Atomic Weights Commission. Fischer was elected a Foreign Member of the Royal Society (ForMemRS) in 1899. He was awarded the 1902 Nobel Prize in chemistry "in recognition of the extraordinary services he has rendered by his work on sugar and purine syntheses."

Many names of chemical reactions and concepts are named after him:

  • Fischer indole synthesis
  • Fischer projection
  • Fischer oxazole synthesis
  • Fischer peptide synthesis
  • Fischer phenylhydrazine and oxazone reaction
  • Fischer–Speier esterification
  • Fischer glycosidation
  • Kiliani–Fischer synthesis

Physiology or Medicine: Ronald Ross, Indian-English physician and mathematician

Sir Ronald Ross (13 May 1857 – 16 September 1932) was a British medical doctor who received the Nobel Prize for Physiology or Medicine in 1902 for his work on the transmission of malaria, becoming the first British Nobel laureate, and the first born outside Europe. His discovery of the malarial parasite in the gastrointestinal tract of a mosquito in 1897 proved that malaria was transmitted by mosquitoes, and laid the foundation for the method of combating the disease. 

He was a polymath, writing a number of poems, published several novels, and composed songs. He was also an amateur artist and natural mathematician. He worked in the Indian Medical Service for 25 years. It was during his service that he made the groundbreaking medical discovery. 

After resigning from his service in India, he joined the faculty of Liverpool School of Tropical Medicine, and continued as Professor and Chairman of Tropical Medicine of the institute for 10 years. In 1926 he became Director-in-Chief of the Ross Institute and Hospital for Tropical Diseases, which was established in honour of his works. He remained there until his death.

Literature: Theodor Mommsen, German archaeologist, journalist, and politician

Christian Matthias Theodor Mommsen (30 November 1817 – 1 November 1903) was a German classical scholar, historian, jurist, journalist, politician and archaeologist. He is widely regarded as one of the greatest classicists of the 19th century. His work regarding Roman history is still of fundamental importance for contemporary research. He received the Nobel Prize in Literature in 1902 for being "the greatest living master of the art of historical writing, with special reference to his monumental work, A History of Rome", after having been nominated by 18 members of the Prussian Academy of Sciences. He was also a prominent German politician, as a member of the Prussian and German parliaments. His works on Roman law and on the law of obligations had a significant impact on the German civil code.

Peace: Élie Ducommun, Swiss journalist and educator

Élie Ducommun (19 February 1833, Geneva – 7 December 1906, Bern) was a Swiss peace activist. He was a Nobel laureate, awarded the 1902 Nobel Peace Prize, which he shared with Charles Albert Gobat.

Born in Geneva, he worked as a tutor, language teacher, journalist and a translator for the Swiss federal Chancellery (1869–1873).

In 1867 he helped to found the Ligue de la paix et de la liberté (League of Peace and Freedom), though he continued working at other positions, including secretary for the Jura-Simplon Steel Company from 1873 to 1891. That year, he was appointed director of the newly formed Bureau international de la paix (International Peace Office), the first non-governmental international peace organization, based in Bern. He refused to accept a salary for the position, stating that he wished to serve in this capacity solely for reasons of idealism.

His keen organizational skills ensured the group's success. He was awarded in the Nobel Peace Prize in 1902, and served as director of the organization until his death in 1906.

Peace: Charles Albert Gobat, Swiss lawyer and politician

Charles Albert Gobat (21 May 1843 – 16 March 1914) was a Swiss lawyer, educational administrator, and politician who jointly received the Nobel Peace Prize with Élie Ducommun in 1902 for their leadership of the Permanent International Peace Bureau.

After completing his Ph.D, Gobat began his practicing law in Bern and also lectured on French civil law at Bern University. He then opened an office in Delémont in the canton of Bern, which soon became the leading legal firm of the district.

After practicing law for fifteen years, he became involved in politics and education. In 1882, he was appointed superintendent of public instruction for the canton of Bern, a position he held for thirty years. He was a progressive in educational philosophy and he made many important reforms in the education system. He reformed the system of primary training, obtained increased budgetary support to improve the teacher-pupil ratio, supported the study of living languages, and provided pupils with an alternative to the traditionally narrow classical education by establishing curricula in vocational & professional training.

He won acclaim for his erudite République de Berne et la France pendant les guerres de religion, which was published in 1891 and also widespread recognition for A People's History of Switzerland, which was published in 1900.

He also pursued a career in politics. He was elected to many important positions. He was elected to the Grand Council of Bern in 1882. From 1884 to 1890, he was a member of the Council of States of Switzerland and from 1890 until his death in 1914, he was a member of the National Council, the other chamber of the central Swiss legislative body. In both politics and education, he was a liberal reformer. In 1902, he sponsored several legislation which applied the principle of arbitration to commercial treaties. Gobat worked with the Inter-Parliamentary Union, which was founded by William Randal Cremer, the winner of the Nobel Peace Prize in 1903, in 1889. In 1892 he became the president of the union's fourth conference, which was held in Bern and which founded the Bureau Interparlementaire. He served as general secretary of the bureau, an information office dealing with peace movements, international conciliation, and communication among national parliamentary bodies. The third conference of the union, held in Rome in 1891, established the International Peace Bureau, of which Gobat was director when it was awarded the Nobel peace prize in 1910.

Each recipient, or "laureate", receives a gold medal, a diploma, and a sum of money, which is decided annually by the Nobel Foundation

Here is a list of 1901 Nobel laureates  

Physics: Wilhelm Röntgen, German physicist and academic

Wilhelm Conrad Röntgen (27 March 1845 – 10 February 1923) was a German mechanical engineer and physicist, who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays, an achievement that earned him the first Nobel Prize in Physics in 1901. In honour of his accomplishments, in 2004 the International Union of Pure and Applied Chemistry (IUPAC) named element 111, roentgenium, a radioactive element with multiple unstable isotopes, after him.

Today, in Remscheid-Lennep, 40 kilometers east of Düsseldorf, the town in which Röntgen was born in 1845 is the Deutsches Röntgen-Museum.
In Würzburg, where he discovered the X-rays, a non-profit organization maintains his laboratory and provides guided tours to the Röntgen Memorial Site.

World Radiology Day: The International Day of Radiology is an annual event promoting the role of medical imaging in modern healthcare. It is celebrated on 8 November each year, coincides with the anniversary of the discovery of X-rays by Wilhelm Roentgen in 1895. It was first introduced in 2012, as a joint initiative, by the European Society of Radiology (ESR), the Radiological Society of North America (RSNA), and the American College of Radiology (ACR).

Chemistry: Jacobus Henricus van 't Hoff, Dutch chemist and academic

Jacobus Henricus "Henry" van 't Hoff Jr. (30 August 1852 – 1 March 1911) was a Dutch physical chemist. A highly influential theoretical chemist of his time, Van 't Hoff was the first winner of the Nobel Prize in Chemistry. His pioneering work helped found the modern theory of chemical affinity, chemical equilibrium, chemical kinetics, and chemical thermodynamics. In his 1874 pamphlet Van 't Hoff formulated the theory of the tetrahedral carbon atom and laid the foundations of stereochemistry. In 1875, he predicted the correct structures of allenes and cumulenes as well as their axial chirality. He is also widely considered one of the founders of physical chemistry as the discipline is known today.

Van 't Hoff earned his earliest reputation in the field of organic chemistry. In 1874, he accounted for the phenomenon of optical activity by assuming that the chemical bonds between carbon atoms and their neighbors were directed towards the corners of a regular tetrahedron. This three-dimensional structure accounted for the isomers found in nature. He shares credit for this with the French chemist Joseph Le Bel, who independently came up with the same idea.

Three months before his doctoral degree was awarded, Van 't Hoff published this theory, which today is regarded as the foundation of stereochemistry, first in a Dutch pamphlet in the fall of 1874, and then in the following May in a small French book entitled La chimie dans l'espace. A German translation appeared in 1877, at a time when the only job Van 't Hoff could find was at the Veterinary School in Utrecht. In these early years his theory was largely ignored by the scientific community, and was sharply criticized by one prominent chemist.

In 1884, Van 't Hoff published his research on chemical kinetics, titled Études de Dynamique chimique ("Studies in Chemical Dynamics"), in which he described a new method for determining the order of a reaction using graphics and applied the laws of thermodynamics to chemical equilibria. He also introduced the modern concept of chemical affinity. In 1886, he showed a similarity between the behaviour of dilute solutions and gases. In 1887, he and German chemist Wilhelm Ostwald founded an influential scientific magazine named Zeitschrift für physikalische Chemie ("Journal of Physical Chemistry"). He worked on Svante Arrhenius's theory of the dissociation of electrolytes and in 1889 provided physical justification for the Arrhenius equation. In 1896, he became a professor at the Prussian Academy of Sciences in Berlin. His studies of the salt deposits at Stassfurt were an important contribution to Prussia's chemical industry.

Van 't Hoff became a lecturer in chemistry and physics at the Veterinary College in Utrecht. He then worked as a professor of chemistry, mineralogy, and geology at the University of Amsterdam for almost 18 years before eventually becoming the chairman of the chemistry department. In 1896, Van 't Hoff moved to Germany, where he finished his career at the University of Berlin in 1911. In 1901, he received the first Nobel Prize in Chemistry for his work with solutions. His work showed that very dilute solutions follow mathematical laws that closely resemble the laws describing the behavior of gases.

Physiology or Medicine: Emil von Behring, German physiologist and immunologist

Emil von Behring (Emil Adolf von Behring), born Emil Adolf Behring (15 March 1854 – 31 March 1917), was a German physiologist who received the 1901 Nobel Prize in Physiology or Medicine, the first one awarded in that field, for his discovery of a diphtheria antitoxin. He was widely known as a "saviour of children," as diphtheria used to be a major cause of child death. He was honored with Prussian nobility in 1901, henceforth being known by the surname "von Behring."

In 1895 he became Professor of Hygienics within the Faculty of Medicine at the University of Marburg, a position he would hold for the rest of his life. He and the pharmacologist Hans Horst Meyer had their laboratories in the same building, and Behring stimulated Meyer's interest in the mode of action of tetanus toxin.

Behring won the first Nobel Prize in Physiology or Medicine in 1901 for the development of serum therapies against diphtheria. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1902.

In 1904 he founded the Behringwerke in Marburg, a company to produce antitoxins and vaccines.

At the International Tuberculosis Congress in 1905 he announced that he had discovered "a substance proceeding from the virus of tuberculosis." This substance, which he designated "T C," plays the important part in the immunizing action of his "bovivaccine", which prevents bovine tuberculosis. He tried unsuccessfully to obtain a protective and therapeutic agents for humans.

Behring died at Marburg, Hessen-Nassau, on 31 March 1917. His name survived in the Dade Behring organisation (now part of the Siemens Healthineers), in CSL Behring, a manufacturer of plasma-derived biotherapies, in Novartis Behring and in the Emil von Behring Prize of the University of Marburg, the highest endowed medicine award in Germany.

His Nobel Prize medal is now kept on display at the International Red Cross and Red Crescent Museum in Geneva.

Literature: Sully Prudhomme, French poet and critic

René François Armand (Sully) Prudhomme (16 March 1839 – 6 September 1907) was a French poet and essayist. He was the first winner of the Nobel Prize in Literature in 1901.

Born in Paris, Prudhomme originally studied to be an engineer, but turned to philosophy and later to poetry; he declared it as his intention to create scientific poetry for modern times. In character sincere and melancholic, he was linked to the Parnassus school, although, at the same time, his work displays characteristics of its own.

His first collection, Stances et Poèmes ("Stanzas and Poems", 1865), was praised by Sainte-Beuve. It included his most famous poem, Le vase brisé. He published more poetry before the outbreak of the Franco-Prussian War. This war, which he discussed in Impressions de la guerre (1872) and La France (1874), permanently damaged his health.

During his career, Prudhomme gradually shifted from the sentimental style of his first books towards a more personal style which unified the formality of the Parnassus school with his interest in philosophical and scientific subjects. One of his inspirations was clearly Lucretius's De rerum natura, whose first book he translated into verse. His philosophy was expressed in La Justice (1878) and Le Bonheur (1888). The extreme economy of means employed in these poems has, however, usually been judged as compromising their poetical quality without advancing their claims as works of philosophy. He was elected to the Académie française in 1881. Another distinction, Chevalier de la Légion d’honneur, was to follow in 1895.

After, Le Bonheur, Prudhomme turned from poetry to write essays on aesthetics and philosophy. He published two important essays: L'Expression dans les beaux-arts (1884) and Réflexions sur l'art des vers (1892), a series of articles on Blaise Pascal in La Revue des Deux Mondes (1890), and an article on free will (La Psychologie du Libre-Arbitre, 1906) in the Revue de métaphysique et de morale.

At the end of his life, his poor health (which had troubled him ever since 1870) forced him to live almost as a recluse at Châtenay-Malabry, suffering attacks of paralysis while continuing to work on essays. He died suddenly on 6 September 1907, and was buried at Père-Lachaise in Paris.

Peace: Henry Dunant, Swiss businessman and activist, co-founded the Red Cross

Henry Dunant (born Jean-Henri Dunant; 8 May 1828 – 30 October 1910), also known as Henri Dunant, was a Swiss humanitarian, businessman and social activist. He was the visionary, promoter and co-founder of the Red Cross.

During a business trip in 1859, Dunant was witness to the aftermath of the Battle of Solferino in modern-day Italy. He recorded his memories and experiences in the book A Memory of Solferino which inspired the creation of the International Committee of the Red Cross (ICRC) in 1863. The 1864 Geneva Convention was based on Dunant's idea for an independent organisation to care for wounded soldiers.

Dunant was the founder of the Swiss branch of the Young Men's Christian Association YMCA.

In 1901 he received the first Nobel Peace Prize together with Frédéric Passy, making Dunant the first Swiss Nobel laureate.

Peace: Frédéric Passy, French economist and academic

Frédéric Passy (20 May 1822 – 12 June 1912) was a French economist and pacifist who was a founding member of several peace societies and the Inter-Parliamentary Union. He was also an author and politician, sitting in the Chamber of Deputies from 1881 until 1889. He was a joint winner of the Nobel Peace Prize in 1901 for his work in the European peace movement.

Born in Paris to a prominent Catholic and Orléanist family, Passy was surrounded by military veterans and politicians. After training in law, he worked as an accountant and served in the National Guard. He soon left this position and began travelling around France giving lectures on economics. Following years of violent conflicts across Europe, Passy joined the peace movement in the 1850s, working with several notable activists and writers to develop journals, articles, and educational curricula.

While sitting in the Chamber of Deputies, Passy developed the Inter-parliamentary Conference (later the Inter-Parliamentary Union) with British MP William Randal Cremer. Alongside this, he founded several peace societies: the Ligue Internationale et Permanente de la Paix, the Société Française des Amis de la Paix, and the Société Française pour l'Arbitrage entre Nations. Passy's work in the peace movement continued into his later years, and in 1901, he was awarded the Nobel Peace Prize alongside Red Cross founder, Henry Dunant.

Passy died in 1912 after a long period of illness and incapacitation. Despite his economic works gaining little traction, his efforts in the peace movement resulted in him being recognised as the "dean of European peace activists".:34 His son, Paul Passy, published a memoir of his life in 1927, and his works are still being republished and translated into English in the 21st Century.

June 26th in stamps Francisco Pizarro is assassinated, Albert I, Prince of Monaco, Peter Rosegger

Here are some events that happened on June 26th. It could be an event or a person that died or was born on that day

1541 – Francisco Pizarro is assassinated in Lima by the son of his former companion and later antagonist, Diego de Almagro the younger. Almagro is later caught and executed.

Francisco Pizarro González (c.1471–1476 – 26 June 1541) was a Spanish conquistador, best known for his expeditions that led to the Spanish conquest of Peru.

Born in Trujillo, Spain to a poor family, Pizarro chose to pursue fortune and adventure in the New World. He went to the Gulf of Urabá, and accompanied Vasco Núñez de Balboa in his crossing of the Isthmus of Panama, where they became the first Europeans to reach the Pacific Ocean. He served as mayor of the newly founded Panama City for a few years, and undertook two failed expeditions to Peru. In 1529, Pizarro obtained permission from the Spanish crown to lead a campaign to conquer Peru and went on his third, and successful, expedition.

When local people who lived along the coast resisted this invasion, Pizarro moved inland and founded the first Spanish settlement in Peru, San Miguel de Piura. After a series of maneuvres, Pizarro captured the Incan emperor Atahualpa at the Battle of Cajamarca in November 1532. A ransom for the emperor's release was demanded and Atahualpa filled a room with gold, but Pizarro charged him with various crimes and executed him in July 1533. The same year, Pizarro entered the Inca capital of Cuzco and completed his conquest of Peru. In January 1535, Pizarro founded the city of Lima.

1918 Died: Peter Rosegger, Austrian poet and author (b. 1843)

Peter Rosegger (original Roßegger ) (31 July 1843 – 26 June 1918) was an Austrian writer and poet from Krieglach in the province of Styria. He was a son of a mountain farmer and grew up in the woodlands and mountains of Alpl. Rosegger (or Rossegger) went on to become a most prolific poet and author as well as an insightful teacher and visionary.

In his later years, he was honored by officials from various Austrian universities and the city of Graz (the capital of Styria). He was nominated for the Nobel Prize in Literature three times. He was nearly awarded the Nobel Prize in 1913 and is (at least among the people of Styria) something like a national treasure to this day.

1922 Died: Albert I, Prince of Monaco (b. 1848)

Albert I (13 November 1848 – 26 June 1922) was Prince of Monaco and Duke of Valentinois from 10 September 1889 until his death. He devoted much of his life to oceanography. Alongside his expeditions, Albert I made reforms on political, economic and social levels, bestowing a constitution on the Principality in 1911.

Prince Albert I of Monaco devoted much of his life to the study of the sea and oceans. At 22 years old, he embarked on a career in the then relatively new science of oceanography. Understanding the importance of the relationship between living creatures and their environment, he devised a number of techniques and instruments for measurement and exploration. Albert I was also the “instigator and promulgator” of the oceanographic science he contributed to create. He founded the Oceanographic Institute Foundation Albert I, Prince of Monaco is a private foundation recognized of public utility, established in 1906. It has two buildings: The Oceanographic Institute of Paris, now renamed Ocean House, and what became the world-renowned Oceanographic Museum of Monaco. This includes an aquarium, a museum, and a library, with research facilities in Paris.

He owned four, increasingly impressive research yachts, Hirondelle, Princesse Alice, Princesse Alice II and Hirondelle II. Accompanied by some of the world's leading marine scientists, he travelled the length and breadth of the Mediterranean, making numerous oceanographic studies, maps and charts. In 1896, on an oceanographic survey of the Azores, he discovered the Princess Alice Bank.
