October 2nd in stamps von Hindenburg, Ferdinand Foch, Cartier, Ghetaldi, Gandhi, Svante Arrhenius, William Ramsay


Here are some events that happened on October 2nd. It could be an event or a person that died or was born on that day


1535 – Jacques Cartier discovers the present site of Montreal

Jacques Cartier (December 31, 1491 – September 1, 1557) was a Breton explorer who claimed what is now Canada for France. Jacques Cartier was the first European to describe and map the Gulf of Saint Lawrence and the shores of the Saint Lawrence River, which he named "The Country of Canadas", after the Iroquois names for the two big settlements he saw at Stadacona (Quebec City) and at Hochelaga (Montreal Island).

1568 Born:  Marino Ghetaldi, Ragusan mathematician and physicist (d. 1626)

Marino Ghetaldi (Latin: Marinus Ghetaldus; Croatian: Marin Getaldić; 2 October 1568 – 11 April 1626) was a Ragusan scientist. A mathematician and physicist who studied in Italy, England and Belgium, his best results are mainly in physics, especially optics, and mathematics. He was one of the few students of François Viète.

Born into the Ghetaldi noble family, he was one of six children. He was known for the application of algebra in geometry and his research in the field of geometrical optics on which he wrote 7 works including the Promotus Archimedus (1603) and the De resolutione et compositione mathematica (1630). He also produced a leaflet with the solutions of 42 geometrical problems, Variorum problematum colletio, in 1607 and set grounds of algebraization of geometry. His contributions to geometry had been cited by Dutch physicist Christiaan Huygens and Edmond Halley, who calculated the orbit of what is known as Halley's comet, in England.

Ghetaldi was the constructor of the parabolic mirror (66 cm in diameter), kept today at the National Maritime Museum in London. He was also a pioneer in making conic lenses. During his sojourn in Padua he met Galileo Galilei, with whom he corresponded regularly. He was a good friend to the French mathematician François Viète. He was offered the post of professor of mathematics in Old University of Leuven in Belgium, at the time one of the most prestigious university centers in Europe.

He was also engaged in politics and was the envoy of the Republic of Ragusa in Constantinople in 1606 as well as the member of the Great and Small Council, the political bodies of the Republic. He was married to Marija Sorkočević, who died giving birth to their third daughter; they had three daughters: Anica, Franica and Marija.

1847 Born: Paul von Hindenburg, Polish-German field marshal and politician, 2nd President of Germany (d. 1934)

Paul Ludwig Hans Anton von Beneckendorff und von Hindenburg, known simply as Paul von Hindenburg (2 October 1847 – 2 August 1934), was a German general and statesman who commanded the Imperial German Army during World War I and later became President of Germany, serving from 1925 until his death in 1934, during the Weimar Republic. He played a key role in the Nazi Machtergreifung in January 1933 when, under pressure from advisers, he appointed Adolf Hitler chancellor of a "Government of National Concentration", even though the Nazis were a minority in both the cabinet and the Reichstag.

Born to a family of minor Prussian nobility, Hindenburg joined the Prussian army in 1866 where he thereafter saw combat during the Austro-Prussian War and the Franco-Prussian conflict. He retired with the rank of General of the Infantry in 1911, but was recalled to military service at the age of 66 following the outbreak of World War I in July 1914. On August 1914, he received nationwide attention as the victor of the Battle of Tannenberg. Upon later being named Chief of the General Staff in 1916, his popularity among the German public exponentially increased to the point of giving rise to an enormous personality cult. As Kaiser Wilhelm II increasingly delegated his power as Supreme Warlord to the Army High Command, Hindenburg and his deputy, General Erich Ludendorff, ultimately established a military dictatorship that controlled Germany for the rest of the war.

Hindenburg retired again in 1919, but returned to public life in 1925 to be elected the second President of Germany. In 1932, he was persuaded to run for re-election even though he was 84 years old and in poor health, because he was considered the only candidate who could defeat Hitler. Hindenburg was re-elected in a runoff. He was opposed to Hitler and was a major player in the increasing political instability in the Weimar Republic that ended with Hitler's rise to power. He dissolved the Reichstag twice in 1932 and finally agreed to appoint Hitler Chancellor of Germany in January 1933. Hindenburg did this to satisfy Hitler's demands that he should play a part in the Weimar government, for Hitler was the leader of the Nazi party, which had won a plurality in the November 1932 elections (no party achieved a majority). In February he approved the Reichstag Fire Decree, which suspended various civil liberties, and in March he signed the Enabling Act of 1933, which gave Hitler's regime arbitrary powers. Hindenburg died the following year, after which Hitler declared himself Führer und Reichskanzler, or Supreme Leader and Chancellor, which superseded both the President and Chancellor.

1851 Born: Ferdinand Foch, French field marshal and theorist (d. 1929)
Ferdinand Foch (2 October 1851 – 20 March 1929) was a French general and military theorist who served as the Supreme Allied Commander during the First World War. An aggressive, even reckless commander at the First Marne, Flanders, and Artois campaigns of 1914–1916, Foch became the Allied Commander-in-Chief in late March 1918 in the face of the all-out German spring offensive, which pushed the Allies back using fresh soldiers and new tactics that trenches could not contain. He successfully coordinated the French, British and American efforts into a coherent whole, deftly handling his strategic reserves. He stopped the German offensive and launched a war-winning counterattack. In November 1918, Marshal Foch accepted the German cessation of hostilities and was present at the armistice of 11 November.

1852 Born: William Ramsay, Scottish-English chemist and academic, Nobel Prize laureate (d. 1916)

Sir William Ramsay (2 October 1852 – 23 July 1916) was a Scottish chemist who discovered the noble gases and received the Nobel Prize in Chemistry in 1904 "in recognition of his services in the discovery of the inert gaseous elements in air" along with his collaborator, John William Strutt, 3rd Baron Rayleigh, who received the Nobel Prize in Physics that same year for their discovery of argon. After the two men identified argon, Ramsay investigated other atmospheric gases. His work in isolating argon, helium, neon, krypton and xenon led to the development of a new section of the periodic table.

1869 Born: Mahatma Gandhi, Indian freedom fighter, activist and philosopher (d. 1948)

Mohandas Karamchand Gandhi (2 October 1869 – 30 January 1948) was an Indian lawyer, anti-colonial nationalist, and political ethicist, who employed nonviolent resistance to lead the successful campaign for India's independence from British Rule, and in turn inspire movements for civil rights and freedom across the world. The honorific Mahātmā (Sanskrit: "great-souled", "venerable"), first applied to him in 1914 in South Africa, is now used throughout the world.

Born and raised in a Hindu family in coastal Gujarat, western India, Gandhi was trained in law at the Inner Temple, London, and called to the bar at age 22 in June 1891. After two uncertain years in India, where he was unable to start a successful law practice, he moved to South Africa in 1893 to represent an Indian merchant in a lawsuit. He went on to stay for 21 years. It was in South Africa that Gandhi raised a family, and first employed nonviolent resistance in a campaign for civil rights. In 1915, aged 45, he returned to India. He set about organizing peasants, farmers, and urban laborers to protest against excessive land-tax and discrimination. Assuming leadership of the Indian National Congress in 1921, Gandhi led nationwide campaigns for easing poverty, expanding women's rights, building religious and ethnic amity, ending untouchability, and above all for achieving Swaraj or self-rule.

The same year Gandhi adopted the Indian loincloth, or short dhoti and, in the winter, a shawl, both woven with yarn hand-spun on a traditional Indian spinning wheel, or charkha, as a mark of identification with India's rural poor. Thereafter, he lived modestly in a self-sufficient residential community, ate simple vegetarian food, and undertook long fasts as a means of self-purification and political protest. Bringing anti-colonial nationalism to the common Indians, Gandhi led them in challenging the British-imposed salt tax with the 400 km (250 mi) Dandi Salt March in 1930, and later in calling for the British to Quit India in 1942. He was imprisoned for many years, upon many occasions, in both South Africa and India.

Gandhi's vision of an independent India based on religious pluralism was challenged in the early 1940s by a new Muslim nationalism which was demanding a separate Muslim homeland carved out of India. In August 1947, Britain granted independence, but the British Indian Empire was partitioned into two dominions, a Hindu-majority India and Muslim-majority Pakistan. As many displaced Hindus, Muslims, and Sikhs made their way to their new lands, religious violence broke out, especially in the Punjab and Bengal. Eschewing the official celebration of independence in Delhi, Gandhi visited the affected areas, attempting to provide solace. In the months following, he undertook several fasts unto death to stop religious violence. The last of these, undertaken on 12 January 1948 when he was 78, also had the indirect goal of pressuring India to pay out some cash assets owed to Pakistan. Some Indians thought Gandhi was too accommodating.  Among them was Nathuram Godse, a Hindu nationalist, who assassinated Gandhi on 30 January 1948 by firing three bullets into his chest

1927 Died: Svante Arrhenius, Swedish physicist and chemist, Nobel Prize laureate (b. 1859)

Svante August Arrhenius (19 February 1859 – 2 October 1927) was a Swedish scientist. Originally a physicist, but often referred to as a chemist, Arrhenius was one of the founders of the science of physical chemistry. He received the Nobel Prize for Chemistry in 1903, becoming the first Swedish Nobel laureate. In 1905, he became director of the Nobel Institute, where he remained until his death.

Arrhenius was the first to use principles of physical chemistry to estimate the extent to which increases in atmospheric carbon dioxide are responsible for the Earth's increasing surface temperature. In the 1960s, Charles David Keeling demonstrated that the quantity of human-caused carbon dioxide emissions into the air is enough to cause global warming.

The Arrhenius equation, Arrhenius acid, Arrhenius base, lunar crater Arrhenius, Martian crater Arrhenius, the mountain of Arrheniusfjellet, and the Arrhenius Labs at Stockholm University were so named to commemorate his contributions to science.

1974 – Guinea-Bissau gains independence from Portugal

Guinea-Bissau, officially the Republic of Guinea-Bissau is a country in West Africa that covers 36,125 square kilometres (13,948 sq mi) with an estimated population of 1,815,698

Guinea-Bissau was once part of the kingdom of Gabu, as well as part of the Mali Empire. Parts of this kingdom persisted until the 18th century, while a few others were under some rule by the Portuguese Empire since the 16th century. In the 19th century, it was colonised as Portuguese Guinea. Upon independence, declared in 1973 and recognised in 1974, the name of its capital, Bissau, was added to the country's name to prevent confusion with Guinea (formerly French Guinea). Guinea-Bissau has a history of political instability since independence, and only one elected president (José Mário Vaz) has successfully served a full five-year term


Independence was unilaterally declared on 24 September 1973. Recognition became universal following 25 April 1974 socialist-inspired military coup in Portugal, which overthrew Lisbon's Estado Novo regime

Here are some events that happened on July 23rd. It could be an event or a person that died or was born on that day


1885 - President Ulysses S. Grant dies of throat cancer

Ulysses S. Grant (born Hiram Ulysses Grant; April 27, 1822 – July 23, 1885) was an American soldier, politician, and international statesman who served as the 18th president of the United States from 1869 to 1877. During the American Civil War, General Grant, with President Abraham Lincoln, led the Union Army to victory over the Confederacy. During the Reconstruction Era, President Grant led the Republicans in their efforts to remove the vestiges of Confederate nationalism, racism, and slavery.

From early childhood in Ohio, Grant was a skilled equestrian who had a talent for taming horses. He graduated from West Point in 1843 and served with distinction in the Mexican–American War. Upon his return, Grant married Julia Dent, and together they had four children. In 1854, Grant abruptly resigned from the army. He and his family struggled financially in civilian life for seven years. When the Civil War broke out in 1861, Grant joined the Union Army and rapidly rose in rank to general. Grant was persistent in his pursuit of the Confederate enemy, winning major battles and gaining Union control of the Mississippi River. In March 1864, President Lincoln promoted Grant to Lieutenant General, a rank previously reserved for George Washington. For over a year Grant's Army of the Potomac fought the Army of Northern Virginia led by Robert E. Lee in the Overland Campaign and at Petersburg. On April 9, 1865, Lee surrendered to Grant at Appomattox, and the war ended.

After a year-long struggle with throat cancer, surrounded by his family, Grant died at 8:08 a.m. in the Mount McGregor cottage on July 23, 1885, at the age of 63.[530] Sheridan, then Commanding General of the Army, ordered a day-long tribute to Grant on all military posts, and President Grover Cleveland ordered a thirty-day nationwide period of mourning

1914 – Austria-Hungary issues a series of demands in an ultimatum to the Kingdom of Serbia demanding Serbia to allow the Austrians to determine who assassinated Archduke Franz Ferdinand. 


Serbia accepts all but one of those demands and Austria declares war on July 28.
The July Crisis was a series of interrelated diplomatic and military escalations among the major powers of Europe in the summer of 1914 that was the penultimate cause of World War I. The 
crisis began on June 28, 1914, when Gavrilo Princip, a Bosnian Serb, assassinated Archduke Franz Ferdinand, heir presumptive to the Austro-Hungarian throne. A complex web of alliances, coupled 
with miscalculations by many leaders that war was in their best interests or that a general war would not occur, resulted in a general outbreak of hostilities among almost every major European 
nation in early August 1914; every major European nation was involved by May 1915.

1999 Died: Hassan II of Morocco (b. 1929)
King Hassan II (9 July 1929 – 23 July 1999) was King of Morocco from 1961 until his death in 1999. He is descended from the Alaouite dynasty. He was the eldest son of Mohammed V, Sultan, then King of Morocco (1909–1961), and his second wife, Lalla Abla bint Tahar (1909–1992). Hassan was known to be one of the most severe rulers of Morocco, widely accused of authoritarian practices and of being an autocrat and a dictator, particularly during the Years of Lead

Hassan died of pneumonia and other health consequences in his birth town at the age of 70 on 23 July 1999. A national funeral service was held for him in Rabat, with over 40 heads of state in attendance. He was buried in the Mausoleum of Mohammed V. The coffin of Hassan II, carried by King Mohammed VI, his brother Prince Moulay Rachid and his cousin Moulay Hicham, was covered with a green fabric, in which the first prayer of Islam, "There is no god but God", is inscribed in golden writing

July 15th in stamps Rembrandt, Rosetta Stone, Champollion, Hermann Emil Fischer


Here are some events that happened on July 15th. It could be an event or a person that died or was born on that day


1606 Born: Rembrandt, Dutch painter and etcher (d. 1669)


Rembrandt Harmenszoon van Rijn (15 July 1606– 4 October 1669) was a Dutch draughtsman, painter and printmaker. An innovative and prolific master in three media, he is generally considered one of the greatest visual artists in the history of art and the most important in Dutch art history. Unlike most Dutch masters of the 17th century, Rembrandt's works depict a wide range of style and subject matter, from portraits and self-portraits to landscapes, genre scenes, allegorical and historical scenes, biblical and mythological themes as well as animal studies. His contributions to art came in a period of great wealth and cultural achievement that historians call the Dutch Golden Age, when Dutch art (especially Dutch painting), although in many ways antithetical to the Baroque style that dominated Europe, was extremely prolific and innovative, and gave rise to important new genres

1799 – The Rosetta Stone is found in the Egyptian village of Rosetta by French Captain Pierre-François Bouchard during Napoleon's Egyptian Campaign.

The Rosetta Stone is a granodiorite stele, rediscovered in the western world in 1799, inscribed with three versions of a decree issued at Memphis, Egypt, in 196 BC during the Ptolemaic dynasty on behalf of King Ptolemy V. The top and middle texts are in Ancient Egyptian using hieroglyphic script and demotic scripts, respectively, while the bottom is in Ancient Greek. As the decree has only minor differences between the three versions, the Rosetta Stone proved to be the key to deciphering Egyptian hieroglyphs, thereby opening a window into ancient Egyptian history

Below are a First Day Cover from Egypt as well as stamps from Egypt, France and Monaco depicting the Rosetta Stone as well as Jean-François Champollion who published his first breakthrough in the decipherment of the Rosetta hieroglyphs in 1822









1919 Died: Hermann Emil Fischer, German chemist and academic, Nobel Prize laureate (b. 1852)

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
