May 19th in stamps Mustafa Kemal Atatürk, Ho Chi Minh, Jacques Cartier
Here are some events that happened on May 19th. It could be an event or a person that died or was born on that day
1535 – French explorer Jacques Cartier sets sail on his second voyage to North America with three ships, 110 men, and Chief Donnacona's two sons (whom Cartier had kidnapped during his first voyage).
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).

1881 Born: Mustafa Kemal Atatürk (official birthday), Turkish field marshal and statesman, 1st President of Turkey (d. 1938)
Kemal Atatürk (or alternatively written as Kamâl Atatürk, Mustafa Kemal Pasha until 1934, commonly referred to as Mustafa Kemal Atatürk; c. 1881 – 10 November 1938) was a Turkish field marshal, revolutionary statesman, author, and the founding father of the Republic of Turkey, serving as its first president from 1923 until his death in 1938. He undertook sweeping progressive reforms, which modernized Turkey into a secular, industrial nation. Ideologically a secularist and nationalist, his policies and theories became known as Kemalism. Due to his military and political accomplishments, Atatürk is regarded as one of the most important political leaders of the 20th century.
Atatürk came to prominence for his role in securing the Ottoman Turkish victory at the Battle of Gallipoli (1915) during World War I. Following the defeat and dissolution of the Ottoman Empire, he led the Turkish National Movement, which resisted mainland Turkey's partition among the victorious Allied powers. Establishing a provisional government in the present-day Turkish capital Ankara (known in English at the time as Angora), he defeated the forces sent by the Allies, thus emerging victorious from what was later referred to as the Turkish War of Independence. He subsequently proceeded to abolish the decrepit Ottoman Empire and proclaimed the foundation of the Turkish Republic in its place.
As the president of the newly formed Turkish Republic, Atatürk initiated a rigorous program of political, economic, and cultural reforms with the ultimate aim of building a modern, progressive and secular nation-state. He made primary education free and compulsory, opening thousands of new schools all over the country. He also introduced the Latin-based Turkish alphabet, replacing the old Ottoman Turkish alphabet. Turkish women received equal civil and political rights during Atatürk's presidency. In particular, women were given voting rights in local elections by Act no. 1580 on 3 April 1930 and a few years later, in 1934, full universal suffrage.
His government carried out a policy of Turkification, trying to create a homogeneous and unified nation. Under Atatürk, non-Turkish minorities were pressured to speak Turkish in public; non-Turkish toponyms and last names of minorities had to be changed to Turkish renditions. The Turkish Parliament granted him the surname Atatürk in 1934, which means "Father of the Turks", in recognition of the role he played in building the modern Turkish Republic. He died on 10 November 1938 at Dolmabahçe Palace in Istanbul, at the age of 57; he was succeeded as President by his long-time Prime Minister İsmet İnönü and was honored with a state funeral. His iconic mausoleum in Ankara, built and opened in 1953, is surrounded by a park called the Peace Park in honor of his famous expression "Peace at Home, Peace in the World".
In 1981, the centennial of Atatürk's birth, his memory was honored by the United Nations and UNESCO, which declared it The Atatürk Year in the World and adopted the Resolution on the Atatürk Centennial, describing him as "the leader of the first struggle given against colonialism and imperialism" and a "remarkable promoter of the sense of understanding between peoples and durable peace between the nations of the world and that he worked all his life for the development of harmony and cooperation between peoples without distinction". Atatürk is commemorated by many memorials and places named in his honor in Turkey and throughout the world.

1890 Born: Ho Chi Minh, Vietnamese politician, 1st President of Vietnam (d. 1969)
Hồ Chí Minh (19 May 1890 – 2 September 1969), born Nguyễn Sinh Cung, also known as Nguyễn Tất Thành, Nguyễn Ái Quốc, Bác Hồ, or simply Bác ('Uncle'), was a Vietnamese revolutionary and politician. He served as Prime Minister of North Vietnam from 1945 to 1955 and President from 1945 until his death in 1969. Ideologically a Marxist–Leninist, he served as Chairman and First Secretary of the Workers' Party of Vietnam.
Hồ Chí Minh led the Việt Minh independence movement from 1941 onward, establishing the Communist-ruled Democratic Republic of Vietnam in 1945 and defeating the French Union in 1954 at the Battle of Điện Biên Phủ, ending the First Indochina War. He was a key figure in the People's Army of Vietnam and the Việt Cộng during the Vietnam War, which lasted from 1955 to 1975. The Democratic Republic of Vietnam was victorious against the Republic of Vietnam and its allies, and was officially reunified with the Republic of South Vietnam in 1976. Saigon, the former capital of South Vietnam, was renamed Ho Chi Minh City in his honor. Ho officially stepped down from power in 1965 due to health problems, and died in 1969.
The details of Hồ Chí Minh's life before he came to power in Vietnam are uncertain. He is known to have used between 50 and 200 pseudonyms. Information on his birth and early life is ambiguous and subject to academic debate. At least four existing official biographies vary on names, dates, places and other hard facts while unofficial biographies vary even more widely.
Aside from being a politician, Ho was also a writer, a poet and a journalist. He wrote several books, articles and poems in French, Chinese and Vietnamese.

May 18th in stamps Roger Joseph Boscovich, Napoleon Bonaparte, Abraham Lincoln, Nicholas II of Russia, Laveran
Here are some events that happened on May 18th. It could be an event or a person that died or was born on that day
1711 Born: Roger Joseph Boscovich, Ragusan physicist, astronomer, and mathematician (d. 1787)
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.

1804 – Napoleon Bonaparte is proclaimed Emperor of the French by the French Senate.
1860 – Abraham Lincoln wins the Republican Party presidential nomination over William H. Seward, who later becomes the United States Secretary of State.
Abraham Lincoln (February 12, 1809 – April 15, 1865) was an American statesman and lawyer who served as the 16th president of the United States from March 1861 until his assassination in April 1865. Lincoln led the nation through the American Civil War, its bloodiest war and its greatest moral, constitutional, and political crisis. He preserved the Union, abolished slavery, strengthened the federal government, and modernized the U.S. economy.
Born in Kentucky, Lincoln grew up on the frontier in a poor family. Self-educated, he became a lawyer, Whig Party leader, Illinois state legislator and Congressman. In 1849, he left government to resume his law practice, but angered by the success of Democrats in opening the prairie lands to slavery, reentered politics in 1854. He became a leader in the new Republican Party and gained national attention in 1858 for debating national Democratic leader Stephen A. Douglas in the 1858 Illinois Senate campaign. He then ran for President in 1860, sweeping the North and winning. Southern pro-slavery elements took his win as proof that the North was rejecting the constitutional rights of Southern states to practice slavery. They began the process of seceding from the union. To secure its independence, the new Confederate States of America fired on Fort Sumter, one of the few U.S. forts in the South. Lincoln called up volunteers and militia to suppress the rebellion and restore the Union.
As the leader of the moderate faction of the Republican Party, Lincoln confronted Radical Republicans, who demanded harsher treatment of the South; War Democrats, who rallied a large faction of former opponents into his camp; anti-war Democrats (called Copperheads), who despised him; and irreconcilable secessionists, who plotted his assassination. Lincoln fought the factions by pitting them against each other, by carefully distributing political patronage, and by appealing to the American people. His Gettysburg Address became an iconic call for nationalism, republicanism, equal rights, liberty, and democracy. He suspended habeas corpus, and he averted British intervention by defusing the Trent Affair. Lincoln closely supervised the war effort, including the selection of generals and the naval blockade that shut down the South's trade. As the war progressed, he maneuvered to end slavery, issuing the Emancipation Proclamation of 1863; ordering the Army to protect escaped slaves, encouraging border states to outlaw slavery, and pushing through Congress the Thirteenth Amendment to the United States Constitution, which outlawed slavery across the country.
Lincoln managed his own re-election campaign. He sought to reconcile his damaged nation by avoiding retribution against the secessionists. A few days after the Battle of Appomattox Court House, he was shot by John Wilkes Booth, an actor and Confederate sympathizer, on April 14, 1865, and died the following day. Abraham Lincoln is remembered as the United States' martyr hero. He is consistently ranked both by scholars and the public as among the greatest U.S. presidents.

1868 Born: Nicholas II of Russia (d. 1918)
1922 Died: Charles Louis Alphonse Laveran, French physician and parasitologist, Nobel Prize laureate (b. 1845)
Charles Louis Alphonse Laveran (18 June 1845 – 18 May 1922) was a French physician who won the Nobel Prize in Physiology or Medicine in 1907 for his discoveries of parasitic protozoans as causative agents of infectious diseases such as malaria and trypanosomiasis. Following his father, Louis Théodore Laveran, he took up military medicine as his profession. He obtained his medical degree from University of Strasbourg in 1867.
At the outbreak of the Franco-Prussian War in 1870, he joined the French Army. At the age of 29 he became Chair of Military Diseases and Epidemics at the École de Val-de-Grâce. At the end of his tenure in 1878 he worked in Algeria, where he made his major achievements. He discovered that the protozoan parasite Plasmodium was responsible for malaria, and that Trypanosoma caused trypanosomiasis or African sleeping sickness. In 1894 he returned to France to serve in various military health services. In 1896 he joined Pasteur Institute as Chief of the Honorary Service, from where he received the Nobel Prize. He donated half of his Nobel prize money to establish the Laboratory of Tropical Medicine at the Pasteur Institute. In 1908, he founded the Société de Pathologie Exotique.
Laveran was elected to French Academy of Sciences in 1893, and was conferred Commander of the National Order of the Legion of Honour in 1912.

May 17th in stamps John Jay, Alfonso XIII of Spain, The Wonderful Wizard of Oz
Here are some events that happened on May 17th. It could be an event or a person that died or was born on that day
1829 Died: John Jay, American politician and diplomat, 1st Chief Justice of the United States (b. 1745)
John Jay (December 12, 1745 – May 17, 1829) was an American statesman, patriot, diplomat, Founding Father, abolitionist, negotiator, and signatory of the Treaty of Paris of 1783. He served as the second Governor of New York and the first Chief Justice of the United States (1789–1795). He directed U.S. foreign policy for much of the 1780s and was an important leader of the Federalist Party after the ratification of the United States Constitution in 1788.
Jay was born into a wealthy family of merchants and New York City government officials of French Huguenot and Dutch descent. He became a lawyer and joined the New York Committee of Correspondence, organizing American opposition to British policies such as the Intolerable Acts in the leadup to the American Revolution. Jay was elected to the Second Continental Congress, and served as President of the Congress. From 1779 to 1782, Jay served as the ambassador to Spain; he persuaded Spain to provide financial aid to the fledgling United States. He also served as a negotiator of the Treaty of Paris, in which Britain recognized American independence. Following the end of the war, Jay served as Secretary of Foreign Affairs, directing United States foreign policy under the Articles of Confederation government. He also served as the first Secretary of State on an interim basis.
A proponent of strong, centralized government, Jay worked to ratify the United States Constitution in New York in 1788. He was a co-author of The Federalist Papers along with Alexander Hamilton and James Madison, and wrote five of the eighty-five essays. After the establishment of the new federal government, Jay was appointed by President George Washington the first Chief Justice of the United States, serving from 1789 to 1795. The Jay Court experienced a light workload, deciding just four cases over six years. In 1794, while serving as Chief Justice, Jay negotiated the highly controversial Jay Treaty with Britain. Jay received a handful of electoral votes in three of the first four presidential elections, but never undertook a serious bid for the presidency.
Jay served as the Governor of New York from 1795 to 1801. Although he successfully passed gradual emancipation legislation as governor of the state, he himself owned five enslaved people as late as 1800. In the waning days of President John Adams's administration, Jay was confirmed by the Senate for another term as Chief Justice, but he declined the position and retired to his farm in Westchester County, New York.

1886 Born: Alfonso XIII of Spain, Spanish monarch (d. 1941)
Alfonso XIII (17 May 1886 – 28 February 1941), also known as El Africano or the African, was King of Spain from 1886 until the proclamation of the Second Republic in 1931. He was a monarch from birth as his father, Alfonso XII, had died the previous year. Alfonso's mother, Maria Christina of Austria, served as regent until he assumed full powers on his sixteenth birthday in 1902.
During Alfonso's reign of the Kingdom of Spain, the country experienced four major problems that contributed to the end of the liberal monarchy: the lack of real political representation of broad social groups; the poor situation of the popular classes, especially peasants; problems arising from the Rif War; and Catalan nationalism. The political and social turbulence that began with the Spanish–American War prevented the turnaround parties from establishing a true liberal democracy, which led to the establishment of the dictatorship of Miguel Primo de Rivera. With the political failure of the dictatorship, Alfonso impelled a return to the democratic normality with the intention of regenerating the regime. Nevertheless, it was abandoned by all political classes, as they felt betrayed by the king's support of the dictatorship of Primo de Rivera.
He left Spain voluntarily after the municipal elections of April 1931, which were taken as a plebiscite on abolishing the monarchy.

1900 – The children's novel The Wonderful Wizard of Oz, by L. Frank Baum, is first published in the United States. The first copy is given to the author's sister.
The Wonderful Wizard of Oz is an American children's novel written by author L. Frank Baum and illustrated by W.W. Denslow, originally published by the George M. Hill Company in May 1900. It has since seen several reprints, most often under the title The Wizard of Oz, which is the title of the popular 1902 Broadway musical adaptation as well as the iconic 1939 live-action film.
The story chronicles the adventures of a young farm girl named Dorothy Gale in the magical Land of Oz after she and her pet dog Toto are swept away from their home in Kansas by a cyclone. The book is one of the best-known stories in American literature and has been widely translated. The Library of Congress has declared it "America's greatest and best-loved homegrown fairytale." Its groundbreaking success, and that of the Broadway musical adapted from the novel led Baum to write thirteen additional Oz books that serve as official sequels to the first story.
In January 1901, George M. Hill Company completed printing the first edition, a total of 10,000 copies, which quickly sold out. It had sold three million copies by the time it entered the public domain in 1956.

May 16th in stamps Vauquelin, Tesla, Django Reinhardt, Tito
Here are some events that happened on May 16th. It could be an event or a person that died or was born on that day
1763 Born: Louis Nicolas Vauquelin, French pharmacist and chemist (d. 1829)
Prof Louis Nicolas Vauquelin (16 May 1763 – 14 November 1829) was a French pharmacist and chemist. He was the discoverer of both chromium and beryllium.
Contributions to chemistry
At first his work appeared as that of his master and patron, then in their joint names; in 1790 he began to publish on his own, and between that year and 1833 his name is associated with 376 papers. Most of these were simple records of patient and laborious analytical operations, and it is perhaps surprising that among all the substances he analysed he only detected two new elements, beryllium in 1798 in beryl and chromium in 1797 in a red lead ore from Siberia. He also managed to get liquid ammonia at atmospheric pressure. Later with Fourcroy, he identified a metal in a platinum residue they called ‘ptène’, This name ‘ptene’ or ‘ptène’ was reported as an early synonym for osmium.
Either together or successively he held the offices of inspector of mines, professor at the School of Mines and at the Polytechnic School, assayer of gold and silver articles, professor of chemistry in the College de France and at the Jardin des Plantes, member of the Council of Industry and Commerce, commissioner on the pharmacy laws, and finally professor of chemistry to the Medical Faculty, to which he succeeded on Fourcroy's death in 1809. His lectures, which were supplemented with practical laboratory teaching, were attended by many chemists who subsequently attained distinction.
A lesser known contribution and finding of his included the study of hens fed a known amount of mineral. "Having calculated all the lime in oats fed to a hen, found still more in the shells of its eggs. Therefore, there is a creation of matter. In that way, no one knows."
Final achievements, days and legacy
From 1809 he was professor at the University of Paris. In 1816, he was elected a foreign member of the Royal Swedish Academy of Sciences. He was elected to the Chamber of Deputies in 1828. In 1806, working with asparagus, he and Pierre Jean Robiquet (future discoverer of the famous red dye alizarin, then a young chemist and his assistant) isolated the amino acid asparagine, the first one to be discovered. He also discovered pectin and malic acid in apples, and isolated camphoric acid and quinic acid. His death occurred while he was on a visit to his birthplace.
Among his best known works is "Manuel de l'essayeur" (Manual of the assayer).
The plant genus Vauquelinia is named in his honor, as is the Vauquelin, an egg white foam associated with molecular gastronomy, and the mineral vauquelinite, discovered at the same mine as the crocoite from which Vauquelin isolated chromium.

1888 – Nikola Tesla delivers a lecture describing the equipment which will allow efficient generation and use of alternating currents to transmit electric power over long distances.
Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian-American inventor, electrical engineer, mechanical engineer, and futurist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system.
Born and raised in the Austrian Empire, Tesla received an advanced education in engineering and physics in the 1870s and gained practical experience in the early 1880s working in telephony and at Continental Edison in the new electric power industry. He emigrated in 1884 to the United States, where he would become a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to develop a range of electrical and mechanical devices. His alternating current (AC) induction motor and related polyphase AC patents, licensed by Westinghouse Electric in 1888, earned him a considerable amount of money and became the cornerstone of the polyphase system which that company would eventually market.
Here are some stamps from Yugoslavia, Moldova, Serbia, Serbia and Montenegro, and India depicting Nikola Tesla
1953 Died: Django Reinhardt, Belgian guitarist and composer (b. 1910)
Jean Reinhardt (23 January 1910 – 16 May 1953), known to all by his Romani nickname Django, was a Belgian-born Romani-French jazz guitarist and composer. He was the first major jazz talent to emerge from Europe and remains the most significant.
With violinist Stéphane Grappelli, Reinhardt formed the Paris-based Quintette du Hot Club de France in 1934. The group was among the first to play jazz that featured the guitar as a lead instrument. Reinhardt recorded in France with many visiting American musicians, including Coleman Hawkins and Benny Carter, and briefly toured the United States with Duke Ellington's orchestra in 1946. He died suddenly of a stroke at the age of 43.
Reinhardt's most popular compositions have become standards within gypsy jazz, including "Minor Swing", "Daphne", "Belleville", "Djangology", "Swing '42", and "Nuages". Jazz guitarist Frank Vignola claims that nearly every major popular-music guitarist in the world has been influenced by Reinhardt. Over the last few decades, annual Django festivals have been held throughout Europe and the U.S., and a biography has been written about his life. In February 2017, the Berlin International Film Festival held the world premiere of the French film Django.

1974 – Josip Broz Tito is elected president for life of Yugoslavia.
Josip Broz (7 May 1892 – 4 May 1980), commonly known as Tito, was a Yugoslav communist revolutionary and statesman, serving in various roles from 1943 until his death in 1980. During World War II, he was the leader of the Partisans, often regarded as the most effective resistance movement in occupied Europe. While his presidency has been criticized as authoritarian and concerns about the repression of political opponents have been raised, Tito has traditionally been seen as a benevolent dictator.
He was a popular public figure both in Yugoslavia and abroad. Viewed as a unifying symbol, his internal policies maintained the peaceful coexistence of the nations of the Yugoslav federation. He gained further international attention as the chief leader of the Non-Aligned Movement, alongside Jawaharlal Nehru of India, Gamal Abdel Nasser of Egypt, and Kwame Nkrumah of Ghana.
Broz was born to a Croat father and Slovene mother in the village of Kumrovec, Austria-Hungary (now in Croatia). Drafted into military service, he distinguished himself, becoming the youngest sergeant major in the Austro-Hungarian Army of that time. After being seriously wounded and captured by the Imperial Russians during World War I, he was sent to a work camp in the Ural Mountains. He participated in some events of the Russian Revolution in 1917 and subsequent Civil War.
Upon his return to the Balkans in 1918, Broz entered the newly established Kingdom of Yugoslavia, where he joined the Communist Party of Yugoslavia (KPJ). He later was elected as General Secretary (later Chairman of the Presidium) of the League of Communists of Yugoslavia (1939–1980). During World War II, after the Nazi invasion of the area, he led the Yugoslav guerrilla movement, the Partisans (1941–1945).
After the war, he was selected as Prime Minister (1944–1963), and President (later President for Life) (1953–1980) of the Socialist Federal Republic of Yugoslavia (SFRY). From 1943 to his death in 1980, Tito held the rank of Marshal of Yugoslavia, serving as the supreme commander of the Yugoslav military, the Yugoslav People's Army (JNA). With a highly favourable reputation abroad in both Cold War blocs, he received some 98 foreign decorations, including the Legion of Honour and the Order of the Bath.
Tito was the chief architect of the second Yugoslavia, a socialist federation that lasted from November 1943 until April 1992. Despite being one of the founders of Cominform, he became the first Cominform member to defy Soviet hegemony in 1948. He was the only leader in Joseph Stalin's time to leave Cominform and begin with his country's own socialist program, which contained elements of market socialism. Economists active in the former Yugoslavia, including Czech-born Jaroslav Vanek and Yugoslav-born Branko Horvat, promoted a model of market socialism that was dubbed the Illyrian model. Firms were socially owned by their employees and structured on workers' self-management; they competed in open and free markets.
Tito built a very powerful cult of personality around himself, which was maintained by the League of Communists of Yugoslavia after his death.
Tito managed to keep ethnic tensions under control by delegating as much power as possible to each republic. The 1974 Yugoslav Constitution defined SFR Yugoslavia as a "federal republic of equal nations and nationalities, freely united on the principle of brotherhood and unity in achieving specific and common interest." Each republic was also given the right to self-determination and secession if done through legal channels. Lastly, Kosovo and Vojvodina, the two constituent provinces of Serbia, received substantially increased autonomy, including de facto veto power in the Serbian parliament.
Ten years after his death, Communism collapsed in Eastern Europe, and Yugoslavia descended into civil war.

April 30th in stamps David Thompson, Carl Friedrich Gauss, Einstein completes his doctoral thesis, Louisiana Statehood, David Thompson
Here are some events that happened on April 30th. It could be an event or a person that died or was born on that day
1770 Born: David Thompson, English-Canadian cartographer and explorer (d. 1857)
David Thompson (30 April 1770 – 10 February 1857) was a British-Canadian fur trader, surveyor, and cartographer, known to some native peoples as Koo-Koo-Sint or "the Stargazer". Over Thompson's career, he traveled some 90,000 kilometers (56,000 mi) across North America, mapping 4.9 million square kilometers (1.9 million square miles) of North America along the way. For this historic feat, Thompson has been described as the "greatest practical land geographer that the world has produced".

1777 Born: Carl Friedrich Gauss, German mathematician and physicist (d. 1855)
Johann Carl Friedrich Gauss (Latin: Carolus Fridericus Gauss; 30 April 1777 – 23 February 1855) was a German mathematician and physicist who made significant contributions to many fields in mathematics and science. Sometimes referred to as the Princeps mathematicorum (Latin for '"the foremost of mathematicians"') and "the greatest mathematician since antiquity", Gauss had an exceptional influence in many fields of mathematics and science, and is ranked among history's most influential mathematicians.

1803 – Louisiana Purchase: The United States purchases the Louisiana Territory from France for $15 million, more than doubling the size of the young nation.
The Louisiana Purchase (French: Vente de la Louisiane 'Sale of Louisiana') was the acquisition of the territory of Louisiana by the United States from France in 1803. In return for fifteen million dollars, the U.S. acquired a total of 828,000 sq mi (2,140,000 km2; 530,000,000 acres). The treaty was negotiated by French Treasury Minister François Barbé-Marbois (acting on behalf of Napoleon) and American delegates James Monroe and Robert R. Livingston (acting on behalf of President Thomas Jefferson).
The Kingdom of France had controlled the Louisiana territory from 1699 until it was ceded to Spain in 1762. In 1800, Napoleon, then the First Consul of the French Republic, regained ownership of Louisiana as part of a broader project to re-establish a French colonial empire in North America. However, France's failure to put down a revolt in Saint-Domingue, coupled with the prospect of renewed warfare with the United Kingdom, prompted Napoleon to consider selling Louisiana to the United States.
Here are some US stamps and a First Day Cover depicting the Louisiana Purchase
1812 – The Territory of Orleans becomes the 18th U.S. state under the name Louisiana.
Louisiana is a state in the Deep South and South Central regions of the United States. It is the 19th-smallest by area and the 25th most populous of the 50 U.S. states. Louisiana is bordered by the state of Texas to the west, Arkansas to the north, Mississippi to the east, and the Gulf of Mexico to the south. A large part of its eastern boundary is demarcated by the Mississippi River. Louisiana is the only U.S. state with political subdivisions termed parishes, which are equivalent to counties. The state's capital is Baton Rouge, and its largest city is New Orleans.
Much of the state's lands were formed from sediment washed down the Mississippi River, leaving enormous deltas and vast areas of coastal marsh and swamp. These contain a rich southern biota; typical examples include birds such as ibises and egrets. There are also many species of tree frogs, and fish such as sturgeon and paddlefish. In more elevated areas, fire is a natural process in the landscape and has produced extensive areas of longleaf pine forest and wet savannas. These support an exceptionally large number of plant species, including many species of terrestrial orchids and carnivorous plants. Louisiana has more Native American tribes than any other southern state, including four that are federally recognized, ten that are state recognized, and four that have not received recognition.
Some Louisiana urban environments have a multicultural, multilingual heritage, being so strongly influenced by a mixture of 18th-century French, Haitian, Spanish, French Canadian, Native American, and African cultures that they are considered to be exceptional in the U.S. Before the American purchase of the territory in 1803, the present-day State of Louisiana had been both a French colony and for a brief period a Spanish one. In addition, colonists imported numerous African people as slaves in the 18th century. Many came from peoples of the same region of West Africa, thus concentrating their culture. In the post-Civil War environment, Anglo-Americans increased the pressure for Anglicization, and in 1921, English was for a time made the sole language of instruction in Louisiana schools before a policy of multilingualism was revived in 1974. There has never been an official language in Louisiana, and the state constitution enumerates "the right of the people to preserve, foster, and promote their respective historic, linguistic, and cultural origins".
Based on national averages, Louisiana frequently ranks low among the U.S. in terms of health, education, and development, and high in measures of poverty. In 2018, Louisiana was ranked as the least healthy state in the country, with high levels of drug-related deaths and excessive alcohol consumption, while it has had the highest homicide rate in the United States since at least the 1990s.

1905 – Albert Einstein completes his doctoral thesis at the University of Zurich.
Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). His work is also known for its influence on the philosophy of science. He is best known to the general public for his mass–energy equivalence formula E = mc2, which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory.
The son of a salesman who later operated an electrochemical factory, Einstein was born in the German Empire but moved to Switzerland in 1895 and renounced his German citizenship in 1896. Specializing in physics and mathematics, he received his academic teaching diploma from the Swiss Federal Polytechnic School (German: eidgenössische polytechnische Schule) in Zürich in 1900. The following year, he acquired Swiss citizenship, which he kept for his entire life. After initially struggling to find work, from 1902 to 1909 he was employed as a patent examiner at the Swiss Patent Office in Bern.
Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led him to develop his special theory of relativity during his time at the Swiss Patent Office. In 1905, called his annus mirabilis (miracle year), he published four groundbreaking papers, which attracted the attention of the academic world; the first outlined the theory of the photoelectric effect, the second paper explained Brownian motion, the third paper introduced special relativity, and the fourth mass-energy equivalence. That year, at the age of 26, he was awarded a PhD by the University of Zurich.
Although initially treated with skepticism from many in the scientific community, Einstein's works gradually came to be recognised as significant advancements. He was invited to teach theoretical physics at the University of Bern in 1908 and the following year moved to the University of Zurich, then in 1911 to Charles University in Prague before returning to ETH (the newly renamed Federal Polytechnic School) in Zürich in 1912. In 1914, he was elected to the Prussian Academy of Sciences in Berlin, where he remained for 19 years. Soon after publishing his work on special relativity, Einstein began working to extend the theory to gravitational fields; he then published a paper on general relativity in 1916, introducing his theory of gravitation. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light and the quantum theory of radiation, the basis of the laser, which laid the foundation of the photon theory of light. In 1917, he applied the general theory of relativity to model the structure of the universe.
In 1933, while Einstein was visiting the United States, Adolf Hitler came to power. Because of his Jewish background, Einstein did not return to Germany. He settled in the United States and became an American citizen in 1940. On the eve of World War II, he endorsed a letter to President Franklin D. Roosevelt alerting FDR to the potential development of "extremely powerful bombs of a new type" and recommending that the US begin similar research. This eventually led to the Manhattan Project. Einstein supported the Allies, but he generally denounced the idea of using nuclear fission as a weapon. He signed the Russell–Einstein Manifesto with British philosopher Bertrand Russell, which highlighted the danger of nuclear weapons. He was affiliated with the Institute for Advanced Study in Princeton, New Jersey, until his death in 1955.
He published more than 300 scientific papers and more than 150 non-scientific works. His intellectual achievements and originality have made the word "Einstein" synonymous with "genius". Eugene Wigner compared him to his contemporaries, writing that "Einstein's understanding was deeper even than Jancsi von Neumann's. His mind was both more penetrating and more original".
