March 5th in stamps Stalin, Mercator, Rosa Luxemburg, Laplace, Volta

Here are some events that happened on March 5th. It could be an event or a person that died or was born on that day


1512 Born: Gerardus Mercator, Flemish mathematician, cartographer, and philosopher (d. 1594)

Gerardus Mercator (5 March 1512 – 2 December 1594) was a 16th-century geographer, cosmographer and cartographer from the County of Flanders. He is most renowned for creating the 1569 world map based on a new projection which represented sailing courses of constant bearing (rhumb lines) as straight lines—an innovation that is still employed in nautical charts.

Mercator was one of the pioneers of cartography and is widely considered the most notable figure of the school in its golden age (approximately 1570s–1670s). In his own day, he was a notable as maker of globes and scientific instruments. In addition, he had interests in theology, philosophy, history, mathematics and geomagnetism. He was also an accomplished engraver and calligrapher. Unlike other great scholars of the age he travelled little and his knowledge of geography came from his library of over one thousand books and maps, from his visitors and from his vast correspondence (in six languages) with other scholars, statesmen, travellers, merchants and seamen. Mercator's early maps were in large formats suitable for wall mounting but in the second half of his life, he produced over 100 new regional maps in a smaller format suitable for binding into his Atlas of 1595. This was the first appearance of the word Atlas in reference to a book of maps. However, Mercator used it as a neologism for a treatise (Cosmologia) on the creation, history and description of the universe, not simply a collection of maps. He chose the word as a commemoration of the Titan Atlas, "King of Mauretania", whom he considered to be the first great geographer.

A large part of Mercator's income came from sales of his terrestrial and celestial globes. For sixty years they were considered the finest in the world, and were sold in such great numbers that there are many surviving examples. This was a substantial enterprise involving the manufacture of the spheres, printing the gores, building substantial stands, packing and distributing all over Europe. He was also renowned for his scientific instruments, particularly his astrolabes and astronomical rings used to study the geometry of astronomy and astrology.

Mercator wrote on geography, philosophy, chronology and theology. All of the wall maps were engraved with copious text on the region concerned. As an example the famous world map of 1569 is inscribed with over five thousand words in fifteen legends. The 1595 Atlas has about 120 pages of maps and illustrated title pages but a greater number of pages are devoted to his account of the creation of the universe and descriptions of all the countries portrayed. His table of chronology ran to some 400 pages fixing the dates (from the time of creation) of earthly dynasties, major political and military events, volcanic eruptions, earthquakes and eclipses. He also wrote on the gospels and the old testament.

Mercator was a devout Christian born into a Catholic family at a time when Martin Luther's Protestantism was gaining ground. He never declared himself as a Lutheran but he was clearly sympathetic and he was accused of heresy by Catholic authorities; after six months in prison he was released unscathed. This period of persecution is probably the major factor in his move from Catholic Leuven (Louvain) to a more tolerant Duisburg, in the Holy Roman Empire, where he lived for the last thirty years of his life. Walter Ghim, Mercator's friend and first biographer, describes him as sober in his behaviour, yet cheerful and witty in company, and never more happy than in debate with other scholars. Above all he was pious and studious until his dying days.

1827 Died: Pierre-Simon Laplace, French mathematician and astronomer (b. 1749)

Pierre-Simon, marquis de Laplace (23 March 1749 – 5 March 1827) was a French scholar and polymath whose work was important to the development of engineering, mathematics, statistics, physics, astronomy, and philosophy. He summarized and extended the work of his predecessors in his five-volume Mécanique Céleste (Celestial Mechanics) (1799–1825). This work translated the geometric study of classical mechanics to one based on calculus, opening up a broader range of problems. In statistics, the Bayesian interpretation of probability was developed mainly by Laplace.

Laplace formulated Laplace's equation, and pioneered the Laplace transform which appears in many branches of mathematical physics, a field that he took a leading role in forming. The Laplacian differential operator, widely used in mathematics, is also named after him. He restated and developed the nebular hypothesis of the origin of the Solar System and was one of the first scientists to postulate the existence of black holes and the notion of gravitational collapse.

Laplace is remembered as one of the greatest scientists of all time. Sometimes referred to as the French Newton or Newton of France, he has been described as possessing a phenomenal natural mathematical faculty superior to that of any of his contemporaries. He was Napoleon's examiner when Napoleon attended the École Militaire in Paris in 1784. Laplace became a count of the Empire in 1806 and was named a marquis in 1817, after the Bourbon Restoration.

1827 Died: Alessandro Volta, Italian physicist and academic (b. 1745)

Alessandro Giuseppe Antonio Anastasio Volta (18 February 1745 – 5 March 1827) was an Italian physicist, chemist, and pioneer of electricity and power who is credited as the inventor of the electric battery and the discoverer of methane. He invented the Voltaic pile in 1799, and reported the results of his experiments in 1800 in a two-part letter to the President of the Royal Society. With this invention Volta proved that electricity could be generated chemically and debunked the prevalent theory that electricity was generated solely by living beings. Volta's invention sparked a great amount of scientific excitement and led others to conduct similar experiments which eventually led to the development of the field of electrochemistry.

Volta also drew admiration from Napoleon Bonaparte for his invention, and was invited to the Institute of France to demonstrate his invention to the members of the Institute. Volta enjoyed a certain amount of closeness with the emperor throughout his life and he was conferred numerous honors by him. Volta held the chair of experimental physics at the University of Pavia for nearly 40 years and was widely idolized by his students.

Despite his professional success, Volta tended to be a person inclined towards domestic life and this was more apparent in his later years. At this time he tended to live secluded from public life and more for the sake of his family until his eventual death in 1827 from a series of illnesses which began in 1823. The SI unit of electric potential is named in his honor as the volt.

1871 Born: Rosa Luxemburg, Polish-Russian economist and philosopher (d. 1919)

Rosa Luxemburg (5 March 1871 – 15 January 1919) was a Polish Marxist, philosopher, economist, anti-war activist and revolutionary socialist who became a naturalized German citizen at the age of 28. Successively, she was a member of the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL), the Social Democratic Party of Germany (SPD), the Independent Social Democratic Party (USPD) and the Communist Party of Germany (KPD).

After the SPD supported German involvement in World War I in 1915, Luxemburg and Karl Liebknecht co-founded the anti-war Spartacus League (Spartakusbund) which eventually became the KPD. During the November Revolution, she co-founded the newspaper Die Rote Fahne (The Red Flag), the central organ of the Spartacist movement. Luxemburg considered the Spartacist uprising of January 1919 a blunder, but supported the attempted overthrow of the government and rejected any attempt at a negotiated solution. Friedrich Ebert's majority SPD government crushed the revolt and the Spartakusbund by sending in the Freikorps, government-sponsored paramilitary groups consisting mostly of World War I veterans. Freikorps troops captured and summarily executed Luxemburg and Liebknecht during the rebellion. Luxemburg's body was thrown in the Landwehr Canal in Berlin.

Due to her pointed criticism of both the Leninist and the more moderate social democratic schools of socialism, Luxemburg has had a somewhat ambivalent reception among scholars and theorists of the political left. Nonetheless, Luxemburg and Liebknecht were extensively idolized as communist martyrs by the East German communist regime. The German Federal Office for the Protection of the Constitution notes that idolization of Luxemburg and Liebknecht is an important tradition of German far-left extremism.

1953 – Joseph Stalin, the longest serving leader of the Soviet Union, dies at his Volynskoe dacha in Moscow after suffering a cerebral hemorrhage 4 days earlier.

Joseph Vissarionovich Stalin (18 December 1878 – 5 March 1953) was a Georgian revolutionary and Soviet politician who led the Soviet Union from the mid–1920s until 1953 as the general secretary of the Communist Party of the Soviet Union (1922–1952) and premier of the Soviet Union (1941–1953). Despite initially governing the Soviet Union as part of a collective leadership, he eventually consolidated power to become the country's de facto dictator by the 1930s. A communist ideologically committed to the Leninist interpretation of Marxism, Stalin formalised these ideas as Marxism–Leninism, while his own policies are known as Stalinism.

Born to a poor family in Gori in the Russian Empire (now Georgia), Stalin joined the Marxist Russian Social Democratic Labour Party as a youth. He edited the party's newspaper, Pravda, and raised funds for Vladimir Lenin's Bolshevik faction via robberies, kidnappings, and protection rackets. Repeatedly arrested, he underwent several internal exiles. After the Bolsheviks seized power during the 1917 October Revolution and created a one-party state under Lenin's newly renamed Communist Party, Stalin joined its governing Politburo. Serving in the Russian Civil War before overseeing the Soviet Union's establishment in 1922, Stalin assumed leadership over the country following Lenin's 1924 death. Under Stalin, "Socialism in One Country" became a central tenet of the party's dogma. Through the Five-Year Plans, the country underwent agricultural collectivisation and rapid industrialisation, creating a centralised command economy. This led to significant disruptions in food production that contributed to the famine of 1932–33. To eradicate accused "enemies of the working class", Stalin instituted the "Great Purge", in which over a million were imprisoned and at least 700,000 executed between 1934 and 1939. By 1937, he had complete personal control over the party and state.

Stalin's government promoted Marxism–Leninism abroad through the Communist International and supported European anti-fascist movements during the 1930s, particularly in the Spanish Civil War. In 1939, it signed a non-aggression pact with Nazi Germany, resulting in the Soviet invasion of Poland. Germany ended the pact by invading the Soviet Union in 1941. Despite initial setbacks, the Soviet Red Army repelled the German incursion and captured Berlin in 1945, ending World War II in Europe. The Soviets annexed the Baltic states and helped establish Soviet-aligned governments throughout Central and Eastern Europe, China, and North Korea. The Soviet Union and the United States emerged from the war as global superpowers. Tensions arose between the Soviet-backed Eastern Bloc and U.S.-backed Western Bloc which became known as the Cold War. Stalin led his country through the post-war reconstruction, during which it developed a nuclear weapon in 1949. In these years, the country experienced another major famine and an anti-semitic campaign peaking in the doctors' plot. After Stalin's death in 1953 he was eventually succeeded by Nikita Khrushchev, who denounced his predecessor and initiated the de-Stalinisation of Soviet society.

Widely considered one of the 20th century's most significant figures, Stalin was the subject of a pervasive personality cult within the international Marxist–Leninist movement which revered him as a champion of the working class and socialism. Since the dissolution of the Soviet Union in 1991, Stalin has retained popularity in Russia and Georgia as a victorious wartime leader who established the Soviet Union as a major world power. Conversely, his totalitarian government has been widely condemned for overseeing mass repressions, ethnic cleansing, deportations, hundreds of thousands of executions, and famines which killed millions.

March 4th in stamps John Adams, Vivaldi, Pulaski, Champollion

Here are some events that happened on March 4th. It could be an event or a person that died or was born on that day


1678 Born: Antonio Vivaldi, Italian violinist and composer (d. 1741)

Antonio Lucio Vivaldi (4 March 1678 – 28 July 1741) was an Italian Baroque musical composer, virtuoso violinist, teacher, and priest. Born in Venice, the capital of the Venetian Republic, he is regarded as one of the greatest Baroque composers, and his influence during his lifetime was widespread across Europe. He composed many instrumental concertos, for the violin and a variety of other instruments, as well as sacred choral works and more than forty operas. His best-known work is a series of violin concertos known as the Four Seasons.

Many of his compositions were written for the all-female music ensemble of the Ospedale della Pietà, a home for abandoned children. Vivaldi had worked there as a Catholic priest for 1 1/2 years and was employed there from 1703 to 1715 and from 1723 to 1740. Vivaldi also had some success with expensive stagings of his operas in Venice, Mantua and Vienna. After meeting the Emperor Charles VI, Vivaldi moved to Vienna, hoping for royal support. However, the Emperor died soon after Vivaldi's arrival, and Vivaldi himself died, in poverty, less than a year later.

1745 Born: Casimir Pulaski, Polish-American general (d. 1779)

Kazimierz Michał Władysław Wiktor Pułaski of Ślepowron (March 4 or March 6, 1745  – October 11, 1779) was a Polish nobleman, soldier and military commander who has been called, together with his counterpart Michael Kovats de Fabriczy, "the father of the American cavalry".

Born in Warsaw and following in his father's footsteps, he became interested in politics at an early age and soon became involved in the military and the revolutionary affairs in the Polish–Lithuanian Commonwealth. Pulaski was one of the leading military commanders for the Bar Confederation and fought against Russian domination of the Commonwealth. When this uprising failed, he was driven into exile. Following a recommendation by Benjamin Franklin, Pulaski travelled to North America to help in the cause of the American Revolutionary War. He distinguished himself throughout the revolution, most notably when he saved the life of George Washington. Pulaski became a general in the Continental Army, created the Pulaski Cavalry Legion and reformed the American cavalry as a whole. At the Battle of Savannah, while leading a daring charge against British forces, he was gravely wounded, and died shortly thereafter.

Pulaski is remembered as a hero who fought for independence and freedom in both Poland and the United States. Numerous places and events are named in his honor, and he is commemorated by many works of art. Pulaski is one of only eight people to be awarded honorary United States citizenship.

1797 – John Adams is inaugurated as the 2nd President of the United States of America, becoming the first President to begin his presidency on March 4.

John Adams (October 30, 1735 – July 4, 1826) was an American statesman, attorney, diplomat, writer, and Founding Father who served as the second president of the United States from 1797 to 1801. Before his presidency he was a leader of the American Revolution that achieved independence from Great Britain, and also served as the first vice president of the United States. Adams was a dedicated diarist and regularly corresponded with many important figures in early American history including his wife and adviser, Abigail, and his letters and other papers are an important source of historical information about the era.

1832 Died: Jean-François Champollion, French philologist and scholar (b. 1790)

Jean-François Champollion, also known as Champollion le jeune ('the Younger') (23 December 1790 – 4 March 1832), was a French scholar, philologist and orientalist, known primarily as the decipherer of Egyptian hieroglyphs and a founding figure in the field of Egyptology. A child prodigy in philology, he gave his first public paper on the decipherment of Demotic in 1806, and already as a young man held many posts of honor in scientific circles, and spoke Coptic and Arabic fluently. During the early 19th-century, French culture experienced a period of 'Egyptomania', brought on by Napoleon's discoveries in Egypt during his campaign there (1798–1801) which also brought to light the trilingual Rosetta Stone. Scholars debated the age of Egyptian civilization and the function and nature of hieroglyphic script, which language if any it recorded, and the degree to which the signs were phonetic (representing speech sounds) or ideographic (recording semantic concepts directly). Many thought that the script was only used for sacred and ritual functions, and that as such it was unlikely to be decipherable since it was tied to esoteric and philosophical ideas, and did not record historical information. The significance of Champollion's decipherment was that he showed these assumptions to be wrong, and made it possible to begin to retrieve many kinds of information recorded by the ancient Egyptians.

Champollion lived in a period of political turmoil in France which continuously threatened to disrupt his research in various ways. During the Napoleonic Wars, he was able to avoid conscription, but his Napoleonic allegiances meant that he was considered suspect by the subsequent Royalist regime. His own actions, sometimes brash and reckless, did not help his case. His relations with important political and scientific figures of the time, such as Joseph Fourier and Silvestre de Sacy helped him, although in some periods he lived exiled from the scientific community.

In 1820, Champollion embarked in earnest on the project of decipherment of hieroglyphic script, soon overshadowing the achievements of British polymath Thomas Young who had made the first advances in decipherment before 1819. In 1822, Champollion published his first breakthrough in the decipherment of the Rosetta hieroglyphs, showing that the Egyptian writing system was a combination of phonetic and ideographic signs – the first such script discovered. In 1824, he published a Précis in which he detailed a decipherment of the hieroglyphic script demonstrating the values of its phonetic and ideographic signs. In 1829, he traveled to Egypt where he was able to read many hieroglyphic texts that had never before been studied, and brought home a large body of new drawings of hieroglyphic inscriptions. Home again he was given a professorship in Egyptology, but only lectured a few times before his health, ruined by the hardships of the Egyptian journey, forced him to give up teaching. He died in Paris in 1832, 41 years old. His grammar of Ancient Egyptian was published posthumously.

During his life as well as long after his death intense discussions over the merits of his decipherment were carried out among Egyptologists. Some faulted him for not having given sufficient credit to the early discoveries of Young, accusing him of plagiarism, and others long disputed the accuracy of his decipherments. But subsequent findings and confirmations of his readings by scholars building on his results gradually led to general acceptance of his work. Although some still argue that he should have acknowledged the contributions of Young, his decipherment is now universally accepted, and has been the basis for all further developments in the field. Consequently, he is regarded as the "Founder and Father of Egyptology".

March 1st in stamps Yellowstone, Becquerel, Hoover Dam, Gabriele D'Annunzio, Jacobus Henricus van 't Hoff

Here are some events that happened on March 1st. It could be an event or a person that died or was born on that day


1872 – Yellowstone National Park is established as the world's first national park.

Yellowstone National Park is an American national park located mostly in Wyoming, with small sections in Montana and Idaho. It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially Old Faithful geyser, one of its most popular features. It has many types of ecosystem, but the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.

Native Americans have lived in the Yellowstone region for at least 11,000 years. Aside from visits by mountain men during the early-to-mid-19th century, organized exploration did not begin until the late 1860s. Management and control of the park originally fell under the jurisdiction of the Secretary of the Interior, the first being Columbus Delano. However, the U.S. Army was subsequently commissioned to oversee management of Yellowstone for a 30-year period between 1886 and 1916. In 1917, administration of the park was transferred to the National Park Service, which had been created the previous year. Hundreds of structures have been built and are protected for their architectural and historical significance, and researchers have examined more than a thousand archaeological sites.

Yellowstone National Park spans an area of 3,468.4 square miles (8,983 km2), comprising lakes, canyons, rivers and mountain ranges. Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest supervolcano on the continent. The caldera is considered a dormant volcano. It has erupted with tremendous force several times in the last two million years. Half of the world's geysers and hydrothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly-intact ecosystem in the Earth's northern temperate zone. In 1978, Yellowstone was named a UNESCO World Heritage Site.

Hundreds of species of mammals, birds, fish, and reptiles have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Yellowstone Park is the largest and most famous megafauna location in the contiguous United States. Grizzly bears, wolves, and free-ranging herds of bison and elk live in this park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States. Forest fires occur in the park each year; in the large forest fires of 1988, nearly one third of the park was burnt. Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls. During the winter, visitors often access the park by way of guided tours that use either snow coaches or snowmobiles.

1896 – Henri Becquerel discovers radioactive decay.

Antoine Henri Becquerel (15 December 1852 – 25 August 1908) was a French engineer, physicist, Nobel laureate, and the first person to discover evidence of radioactivity. For work in this field he, along with Marie Skłodowska-Curie (Marie Curie) and Pierre Curie, received the 1903 Nobel Prize in Physics. The SI unit for radioactivity, the becquerel (Bq), is named after him.

1911 Died: Jacobus Henricus van 't Hoff, Dutch chemist and academic, Nobel Prize laureate (b. 1852)

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.

1936 – The Hoover Dam is completed.

Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. Originally known as Boulder Dam from 1933, it was officially renamed Hoover Dam, for President Herbert Hoover, by a joint resolution of Congress in 1947.

Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water and produce hydroelectric power. In 1928, Congress authorized the project. The winning bid to build the dam was submitted by a consortium called Six Companies, Inc., which began construction of the dam in early 1931. Such a large concrete structure had never been built before, and some of the techniques were unproven. The torrid summer weather and lack of facilities near the site also presented difficulties. Nevertheless, Six Companies turned the dam over to the federal government on March 1, 1936, more than two years ahead of schedule.

Hoover Dam impounds Lake Mead, the largest reservoir in the United States by volume (when it is full). The dam is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 30 mi (48 km) southeast of Las Vegas, Nevada. The dam's generators provide power for public and private utilities in Nevada, Arizona, and California. Hoover Dam is a major tourist attraction; nearly a million people tour the dam each year. The heavily traveled U.S. Route 93 (US 93) ran along the dam's crest until October 2010, when the Hoover Dam Bypass opened.

1938 Died: Gabriele D'Annunzio, Italian journalist and politician (b. 1863)

General Gabriele D'Annunzio, Prince of Montenevoso, Duke of Gallese (12 March 1863 – 1 March 1938), sometimes spelled d'Annunzio, was an Italian poet, journalist, playwright and soldier during World War I. He occupied a prominent place in Italian literature from 1889 to 1910 and later political life from 1914 to 1924. He was often referred to under the epithets Il Vate ("the Poet") or Il Profeta ("the Prophet").

D'Annunzio was associated with the Decadent movement in his literary works, which interplayed closely with French Symbolism and British Aestheticism. Such works represented a turn against the naturalism of the preceding romantics and was both sensuous and mystical. He came under the influence of Friedrich Nietzsche which would find outlets in his literary and later political contributions. His affairs with several women, including Eleonora Duse and Luisa Casati, received public attention.

During the First World War, perception of D'Annunzio in Italy transformed from literary figure into a national war hero. He was associated with the elite Arditi storm troops of the Italian Army and took part in actions such as the Flight over Vienna. As part of an Italian nationalist reaction against the Paris Peace Conference, he set up the short-lived Italian Regency of Carnaro in Fiume with himself as Duce. The constitution made "music" the fundamental principle of the state and was corporatist in nature. Though D'Annunzio never declared himself a fascist, he has been described as the forerunner of Italian fascism as his ideas and aesthetics influenced it and the style of Benito Mussolini.

February 13th in stamps Galileo, Boscovich,Wagner, German reunification

Here are some events that happened on February 13th. It could be an event or a person that died or was born on that day


1633 – Galileo Galilei arrives in Rome for his trial before the Inquisition.

Galileo di Vincenzo Bonaulti de Galilei (15 February 1564 – 8 January 1642) was an Italian astronomer, physicist and engineer, sometimes described as a polymath, from Pisa. Galileo has been called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method", and the "father of modern science".

Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and "hydrostatic balances", inventing the thermoscope and various military compasses, and using the telescope for scientific observations of celestial objects. His contributions to observational astronomy include the telescopic confirmation of the phases of Venus, the observation of the four largest satellites of Jupiter, the observation of Saturn's rings, and the analysis of sunspots.

Galileo's championing of heliocentrism and Copernicanism was controversial during his lifetime, when most subscribed to geocentric models such as the Tychonic system. He met with opposition from astronomers, who doubted heliocentrism because of the absence of an observed stellar parallax. The matter was investigated by the Roman Inquisition in 1615, which concluded that heliocentrism was "foolish and absurd in philosophy, and formally heretical since it explicitly contradicts in many places the sense of Holy Scripture".

Galileo later defended his views in Dialogue Concerning the Two Chief World Systems (1632), which appeared to attack Pope Urban VIII and thus alienated him and the Jesuits, who had both supported Galileo up until this point. He was tried by the Inquisition, found "vehemently suspect of heresy", and forced to recant. He spent the rest of his life under house arrest. While under house arrest, he wrote Two New Sciences, in which he summarized work he had done some forty years earlier on the two sciences now called kinematics and strength of materials.

1787 Died: Roger Joseph Boscovich, Croatian physicist, astronomer, mathematician, and philosopher (b. 1711)

Roger Joseph Boscovich (18 May 1711 – 13 February 1787) was a physicist, astronomer, mathematician, philosopher, diplomat, poet, theologian, Jesuit priest, and a polymath from the Republic of Ragusa (modern-day Dubrovnik, Croatia). He studied and lived in Italy and France where he also published many of his works.

Boscovich produced a precursor of atomic theory and made many contributions to astronomy, including the first geometric procedure for determining the equator of a rotating planet from three observations of a surface feature and for computing the orbit of a planet from three observations of its position. In 1753 he also discovered the absence of atmosphere on the Moon.

1883 Died: Richard Wagner, German composer (b. 1813)

Wilhelm Richard Wagner (22 May 1813 – 13 February 1883) was a German composer, theatre director, polemicist, and conductor who is chiefly known for his operas (or, as some of his mature works were later known, "music dramas"). Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works. Initially establishing his reputation as a composer of works in the romantic vein of Carl Maria von Weber and Giacomo Meyerbeer, Wagner revolutionised opera through his concept of the Gesamtkunstwerk ("total work of art"), by which he sought to synthesise the poetic, visual, musical and dramatic arts, with music subsidiary to drama. He described this vision in a series of essays published between 1849 and 1852. Wagner realised these ideas most fully in the first half of the four-opera cycle Der Ring des Nibelungen (The Ring of the Nibelung).

His compositions, particularly those of his later period, are notable for their complex textures, rich harmonies and orchestration, and the elaborate use of leitmotifs—musical phrases associated with individual characters, places, ideas, or plot elements. His advances in musical language, such as extreme chromaticism and quickly shifting tonal centres, greatly influenced the development of classical music. His Tristan und Isolde is sometimes described as marking the start of modern music.

Wagner had his own opera house built, the Bayreuth Festspielhaus, which embodied many novel design features. The Ring and Parsifal were premiered here and his most important stage works continue to be performed at the annual Bayreuth Festival, run by his descendants. His thoughts on the relative contributions of music and drama in opera were to change again, and he reintroduced some traditional forms into his last few stage works, including Die Meistersinger von Nürnberg (The Mastersingers of Nuremberg).

Until his final years, Wagner's life was characterised by political exile, turbulent love affairs, poverty and repeated flight from his creditors. His controversial writings on music, drama and politics have attracted extensive comment, notably, since the late 20th century, where they express antisemitic sentiments. The effect of his ideas can be traced in many of the arts throughout the 20th century; his influence spread beyond composition into conducting, philosophy, literature, the visual arts and theatre.

1990 – German reunification: An agreement is reached on a two-stage plan to reunite Germany.

German reunification (German: Deutsche Wiedervereinigung) was the process in 1990 in which the German Democratic Republic became part of the Federal Republic of Germany to form the reunited nation of Germany, as provided by Article 23 of the Federal Republic of Germany's then constitution (Grundgesetz). The end of the unification process is officially referred to as German unity (German: Deutsche Einheit), celebrated each year on 3 October as German Unity Day (German: Tag der deutschen Einheit). Berlin was reunited into a single city, and was once again designated as the capital of united Germany.

The East German government started to falter in May 1989, when the removal of Hungary's border fence with Austria opened a hole in the Iron Curtain. It caused an exodus of thousands of East Germans fleeing to West Germany and Austria via Hungary. The Peaceful Revolution, a series of protests by East Germans, led to the GDR's first free elections on 18 March 1990, and to the negotiations between the GDR and FRG that culminated in a Unification Treaty. Other negotiations between the GDR and FRG and the four occupying powers produced the so-called "Two Plus Four Treaty" (Treaty on the Final Settlement with Respect to Germany) granting full sovereignty to a unified German state, whose two parts were previously bound by a number of limitations stemming from their post-World War II status as occupied regions.

The 1945 Potsdam Agreement had specified that a full peace treaty concluding World War II, including the exact delimitation of Germany's postwar boundaries, required to be "accepted by the Government of Germany when a government adequate for the purpose is established." The Federal Republic had always maintained that no such government could be said to have been established until East and West Germany had been united within a free democratic state; but in 1990 a range of opinions continued to be maintained over whether a unified West Germany, East Germany, and Berlin could be said to represent "Germany as a whole" for this purpose. The key question was whether a Germany that remained bounded to the east by the Oder–Neisse line could act as a "united Germany" in signing the peace treaty without qualification. Under the "Two Plus Four Treaty" both the Federal Republic and the Democratic Republic committed themselves and their unified continuation to the principle that their joint pre-1990 boundaries constituted the entire territory that could be claimed by a Government of Germany, and hence that there were no further lands outside those boundaries that were parts of Germany as a whole.

The post-1990 united Germany is not a successor state, but an enlarged continuation of the former West Germany. As such, the enlarged Federal Republic of Germany retained the West German seats in international organizations including the European Community (later the European Union) and NATO, while relinquishing membership in the Warsaw Pact and other international organizations to which only East Germany belonged. It also maintains the United Nations membership of the old West Germany.
