May 27th in stamps Saint Petersburg, Paganini, Garibaldi, Alexander III, Robert Koch

Here are some events that happened on May 27th. It could be an event or a person that died or was born on that day

1703 – Tsar Peter the Great founds the city of Saint Petersburg.

Peter the Great (Peter I or Peter Alexeyevich 9 June 1672 – 8 February 1725) ruled the Tsardom of Russia and later the Russian Empire from 7 May 1682 until his death in 1725, jointly ruling before 1696 with his elder half-brother, Ivan V. Through a number of successful wars, he expanded the Tsardom into a much larger empire that became a major European power and also laid the groundwork for the Russian navy after capturing ports at Azov and the Baltic Sea. He led a cultural revolution that replaced some of the traditionalist and medieval social and political systems with ones that were modern, scientific, Westernised and based on the Enlightenment. Peter's reforms had a lasting impact on Russia, and many institutions of the Russian government trace their origins to his reign. He is also known for founding and developing the city of Saint Petersburg, which remained the capital of Russia until 1917.

1840 Died: Niccolò Paganini, Italian violinist and composer (b. 1782)

Niccolò (or Nicolò) Paganini (27 October 1782 – 27 May 1840) was an Italian violinist, violist, guitarist, and composer. He was the most celebrated violin virtuoso of his time, and left his mark as one of the pillars of modern violin technique. His 24 Caprices for Solo Violin Op. 1 are among the best known of his compositions, and have served as an inspiration for many prominent composers.

Niccolò Paganini was born in Genoa, then capital of the Republic of Genoa, the third of the six children of Antonio and Teresa (née Bocciardo) Paganini. Paganini's father was an unsuccessful trader, but he managed to supplement his income by playing music on the mandolin. At the age of five, Paganini started learning the mandolin from his father and moved to the violin by the age of seven. His musical talents were quickly recognized, earning him numerous scholarships for violin lessons. The young Paganini studied under various local violinists, including Giovanni Servetto and Giacomo Costa, but his progress quickly outpaced their abilities. Paganini and his father then traveled to Parma to seek further guidance from Alessandro Rolla. But upon listening to Paganini's playing, Rolla immediately referred him to his own teacher, Ferdinando Paer and, later, Paer's own teacher, Gasparo Ghiretti. Though Paganini did not stay long with Paer or Ghiretti, the two had considerable influence on his composition style.

The French invaded northern Italy in March 1796, and Genoa was not spared. The Paganinis sought refuge in their country property in Romairone, near Bolzaneto. It was in this period that Paganini is thought to have developed his relationship with the guitar. He mastered the guitar, but preferred to play it in exclusively intimate, rather than public concerts. He later described the guitar as his "constant companion" on his concert tours. By 1800, Paganini and his father traveled to Livorno, where Paganini played in concerts and his father resumed his maritime work. In 1801, the 18-year-old Paganini was appointed first violin of the Republic of Lucca, but a substantial portion of his income came from freelancing. His fame as a violinist was matched only by his reputation as a gambler and womanizer.

In 1805, Lucca was annexed by Napoleonic France, and the region was ceded to Napoleon's sister, Elisa Baciocchi. Paganini became a violinist for the Baciocchi court, while giving private lessons to Elisa's husband, Felice. In 1807, Baciocchi became the Grand Duchess of Tuscany and her court was transferred to Florence. Paganini was part of the entourage, but, towards the end of 1809, he left Baciocchi to resume his freelance career.

For the next few years, Paganini returned to touring in the areas surrounding Parma and Genoa. Though he was very popular with the local audience, he was still not very well known in the rest of Europe. His first break came from an 1813 concert at La Scala in Milan. The concert was a great success. As a result, Paganini began to attract the attention of other prominent, though more conservative, musicians across Europe. His early encounters with Charles Philippe Lafont and Louis Spohr created intense rivalry. His concert activities, however, were still limited to Italy for the next few years.

In 1827, Pope Leo XII honoured Paganini with the Order of the Golden Spur. His fame spread across Europe with a concert tour that started in Vienna in August 1828, stopping in every major European city in Germany, Poland, and Bohemia until February 1831 in Strasbourg. This was followed by tours in Paris and Britain. His technical ability and his willingness to display it received much critical acclaim. In addition to his own compositions, theme and variations being the most popular, Paganini also performed modified versions of works (primarily concertos) written by his early contemporaries, such as Rodolphe Kreutzer and Giovanni Battista Viotti.

Paganini's travels also brought him into contact with eminent guitar virtuosi of the day, including Ferdinando Carulli in Paris and Mauro Giuliani in Vienna. But this experience did not inspire him to play public concerts with guitar, and even performances of his own guitar trios and quartets were private to the point of being behind closed doors.

Throughout his life, Paganini was no stranger to chronic illnesses. Although no definite medical proof exists, he was reputed to have been affected by Marfan syndrome or Ehlers–Danlos syndrome. In addition, his frequent concert schedule, as well as his extravagant lifestyle, took their toll on his health. He was diagnosed with syphilis as early as 1822, and his remedy, which included mercury and opium, came with serious physical and psychological side effects. In 1834, while still in Paris, he was treated for tuberculosis. Though his recovery was reasonably quick, after the illness his career was marred by frequent cancellations due to various health problems, from the common cold to depression, which lasted from days to months.

In September 1834, Paganini put an end to his concert career and returned to Genoa. Contrary to popular beliefs involving his wishing to keep his music and techniques secret, Paganini devoted his time to the publication of his compositions and violin methods. He accepted students, of whom two enjoyed moderate success: violinist Camillo Sivori and cellist Gaetano Ciandelli. Neither, however, considered Paganini helpful or inspirational. In 1835, Paganini returned to Parma, this time under the employ of Archduchess Marie Louise of Austria, Napoleon's second wife. He was in charge of reorganizing her court orchestra. However, he eventually conflicted with the players and court, so his visions never saw completion. In Paris, he befriended the 11-year-old Polish virtuoso Apollinaire de Kontski, giving him some lessons and a signed testimonial. It was widely put about, falsely, that Paganini was so impressed with de Kontski's skills that he bequeathed him his violins and manuscripts.

In 1836, Paganini returned to Paris to set up a casino. Its immediate failure left him in financial ruin, and he auctioned off his personal effects, including his musical instruments, to recoup his losses. At Christmas of 1838, he left Paris for Marseilles and, after a brief stay, travelled to Nice where his condition worsened. In May 1840, the Bishop of Nice sent Paganini a local parish priest to perform the last rites. Paganini assumed the sacrament was premature, and refused.

A week later, on 27 May 1840, Paganini died from internal hemorrhaging before a priest could be summoned. Because of this, and his widely rumored association with the devil, the Church denied his body a Catholic burial in Genoa. It took four years and an appeal to the Pope before the Church let his body be transported to Genoa, but it was still not buried. His body was finally buried in 1876, in a cemetery in Parma. In 1893, the Czech violinist František Ondříček persuaded Paganini's grandson, Attila, to allow a viewing of the violinist's body. After this episode, Paganini's body was finally reinterred in a new cemetery in Parma in 1896.

1860 – Giuseppe Garibaldi begins his attack on Palermo, Sicily, as part of the Italian unification.

Giuseppe Maria Garibaldi (4 July 1807 – 2 June 1882) was an Italian general and nationalist. A republican, he contributed to the Italian unification and the creation of the Kingdom of Italy. He is considered one of the greatest generals of modern times and one of Italy's "fathers of the fatherland" along with Camillo Benso, Count of Cavour, Victor Emmanuel II of Italy and Giuseppe Mazzini.

Garibaldi is also known as the "Hero of the Two Worlds" because of his military enterprises in Brazil, Uruguay, and Europe.He commanded and fought in many military campaigns that eventually led to the Italian unification. In 1848, the provisional government of Milan made Garibaldi a general, and in 1849, the Minister of War promoted him to General of the Roman Republic to lead the Expedition of the Thousand on behalf and with the consent of Victor Emmanuel II. His last military campaign took place during the Franco-Prussian War, as commander of the Army of the Vosges.

Having conquered Sicily, he crossed the Strait of Messina and marched north. Garibaldi's progress was met with more celebration than resistance, and on 7 September he entered the capital city of Naples, by train. Despite taking Naples, however, he had not to this point defeated the Neapolitan army. Garibaldi's volunteer army of 24,000 was not able to defeat conclusively the reorganized Neapolitan army—about 25,000 men—on 30 September at the battle of Volturno. This was the largest battle he ever fought, but its outcome was effectively decided by the arrival of the Piedmontese Army.

1883 – Alexander III is crowned Tsar of Russia.

Alexander III (10 March 1845 – 1 November 1894) was Emperor of Russia, King of Poland and Grand Duke of Finland from 13 March 1881 until his death on 1 November 1894. He was highly reactionary and reversed some of the liberal reforms of his father, Alexander II. Under the influence of Konstantin Pobedonostsev (1827–1907) he opposed any reform that limited his autocratic rule. During his reign, Russia fought no major wars; he was therefore styled "The Peacemaker"

In 1894, Alexander III became ill with terminal kidney disease (nephritis). Maria Fyodorovna's sister-in-law, Queen Olga of Greece, offered her villa of Mon Repos, on the island of Corfu, in the hope that it might improve the Tsar's condition. By the time that they reached Crimea, they stayed at the Maly Palace in Livadia, as Alexander was too weak to travel any further. Recognizing that the Tsar's days were numbered, various imperial relatives began to descend on Livadia. Even the famed clergyman John of Kronstadt paid a visit and administered Communion to the Tsar. On 21 October, Alexander received Nicholas's fiancée, Princess Alix, who had come from her native Darmstadt to receive the Tsar's blessing. Despite being exceedingly weak, Alexander insisted on receiving Alix in full dress uniform, an event that left him exhausted. Soon after, his health began to deteriorate more rapidly. He died in the arms of his wife, and in the presence of his physician, Ernst Viktor von Leyden, at Maly Palace in Livadia on the afternoon of 1 November 1894 at the age of forty-nine, and was succeeded by his eldest son Tsesarevich Nicholas, who took the throne as Nicholas II. After leaving Livadia on 6 November and traveling to St. Petersburg by way of Moscow, his remains were interred on 18 November at the Peter and Paul Fortress.

1910 Died: Robert Koch, German physician and microbiologist, Nobel Prize laureate (b. 1843)

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


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

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

Here are some events that happened on May 21st. It could be an event or a person that died or was born on that day

1471 Born: Albrecht Dürer, German painter, engraver, and mathematician (d. 1528)

Albrecht Dürer (21 May 1471 – 6 April 1528), sometimes spelt in English as Durer or Duerer, without umlaut, was a German painter, printmaker, and theorist of the German Renaissance. Born in Nuremberg, Dürer established his reputation and influence across Europe when he was in his twenties due to his high-quality woodcut prints. He was in communication with the major Italian artists of his time, including Raphael, Giovanni Bellini and Leonardo da Vinci, and from 1512 he was patronized by Emperor Maximilian I. Dürer is commemorated by both the Lutheran and Episcopal Churches.

Dürer's vast body of work includes engravings, his preferred technique in his later prints, altarpieces, portraits and self-portraits, watercolours and books. The woodcuts, such as the Apocalypse series (1498), are more Gothic than the rest of his work. His well-known engravings include the Knight, Death and the Devil (1513), Saint Jerome in his Study (1514) and Melencolia I (1514), which has been the subject of extensive analysis and interpretation. His watercolours also mark him as one of the first European landscape artists, while his ambitious woodcuts revolutionized the potential of that medium.

Dürer's introduction of classical motifs into Northern art, through his knowledge of Italian artists and German humanists, has secured his reputation as one of the most important figures of the Northern Renaissance. This is reinforced by his theoretical treatises, which involve principles of mathematics, perspective, and ideal proportions.

Albrecht Dürer has been credited with inventing the basic principle of ray tracing, a technique used in modern computer graphics.

1647 Died: Pieter Corneliszoon Hooft, Dutch poet and playwright (b. 1581)

Pieter Corneliszoon Hooft (16 March 1581 in Amsterdam – 21 May 1647 in The Hague) - Knight in the Order of Saint Michael - was a Dutch historian, poet and playwright who lived during the Dutch Golden Age.

Pieter Corneliszoon Hooft, often abbreviated to P.C. Hooft, was born in Amsterdam as the son of the then mayor, Cornelis Hooft. Hooft was also uncle to Cornelis and Andries de Graeff.

In 1598, in preparation for his career as a merchant, his father sent him to France and Italy, but Pieter Corneliszoon Hooft was more interested in art and was deeply impressed by the Italian renaissance.

Hooft was a prolific writer of plays, poems and letters, but from 1618 onwards he concentrated on writing a history of the Netherlands (Nederduytsche Historiën), inspired by Roman historian Tacitus. His focus was primarily on the Eighty Years' War between the Netherlands and Spain and though he tried to be as impartial as possible, he did succeed.

As a poet, he was influenced by his Renaissance contemporaries in France and Italy.

1686 Died: Otto von Guericke, German physicist and inventor of the Magdeburg Hemispheres (b. 1602)

Otto von Guericke (November 20, 1602 – May 11, 1686 [Julian calendar]; November 30, 1602 – May 21, 1686 [Gregorian calendar]) was a German scientist, inventor, and politician. His major scientific achievements were the establishment of the physics of vacuums, the discovery of an experimental method for clearly demonstrating electrostatic repulsion, and his advocacy for the reality of "action at a distance" and of "absolute space".

He was also a very spiritual man in the Dionysiac tradition, as were many scientists of the Enlightenment, and connected the vacuum of space to an infinite divinity. Von Guericke described this duality "as something that ‘contains all things’ and is ‘more precious than gold...more joyous that the perception of bountiful light’ and ‘comparable to the heavens’."

1703 – Daniel Defoe is imprisoned on charges of seditious libel

Daniel Defoe (born Daniel Foe; c. 1660 – 24 April 1731) was an English trader, writer, journalist, pamphleteer and spy. He is most famous for his novel Robinson Crusoe, published in 1719, which is claimed to be second only to the Bible in its number of translations. He has been seen as one of the earliest proponents of the English novel, and helped to popularize the form in Britain with others such as Aphra Behn and Samuel Richardson. Defoe wrote many political tracts and was often in trouble with the authorities, and spent a period in prison. Intellectuals and political leaders paid attention to his fresh ideas and sometimes consulted with him.

Defoe was a prolific and versatile writer, producing more than three hundred works—books, pamphlets, and journals—on diverse topics, including politics, crime, religion, marriage, psychology, and the supernatural. He was also a pioneer of business journalism and economic journalism.

1843 Born: Charles Albert Gobat, Swiss lawyer and politician, Nobel Prize laureate (d. 1914)

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

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

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

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

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

1844 Born: Henri Rousseau, French painter (d. 1910)

Henri Julien Félix Rousseau (21 May 1844 – 2 September 1910) was a French post-impressionist painter in the Naïve or Primitive manner. He was also known as Le Douanier (the customs officer), a humorous description of his occupation as a toll and tax collector. He started painting seriously in his early forties; by age 49, he retired from his job to work on his art full-time.

Ridiculed during his lifetime by critics, he came to be recognized as a self-taught genius whose works are of high artistic quality.[5][6] Rousseau's work exerted an extensive influence on several generations of avant-garde artists

At his funeral, seven friends stood at his grave: the painters Paul Signac and Manuel Ortiz de Zárate, the artist couple Robert Delaunay and Sonia Terk, the sculptor Brâncuși, Rousseau's landlord Armand Queval, and Guillaume Apollinaire who wrote the epitaph Brâncuși put on the tombstone:

We salute you Gentle Rousseau you can hear us.
Delaunay, his wife, Monsieur Queval and myself.
Let our luggage pass duty free through the gates of heaven.
We will bring you brushes paints and canvas.
That you may spend your sacred leisure in the
light and Truth of Painting.
As you once did my portrait facing the stars, lion and the gypsy.

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.

Napoleon Bonaparte (15 August 1769 – 5 May 1821), born Napoleone di Buonaparte, was a French statesman and military leader who became famous as an artillery commander during the French Revolution. He led many successful campaigns during the French Revolutionary Wars and was Emperor of the French as Napoleon I from 1804 until 1814 and again briefly in 1815 during the Hundred Days. Napoleon dominated European and global affairs for more than a decade while leading France against a series of coalitions during the Napoleonic Wars. He won many of these wars and a vast majority of his battles, building a large empire that ruled over much of continental Europe before its final collapse in 1815. He is considered one of the greatest commanders in history, and his wars and campaigns are studied at military schools worldwide. Napoleon's political and cultural legacy has made him one of the most celebrated and controversial leaders in human history.  

Napoleon's influence on the modern world brought liberal reforms to the numerous territories that he conquered and controlled, such as the Low Countries, Switzerland, and large parts of modern Italy and Germany. He implemented fundamental liberal policies in France and throughout Western Europe. His Napoleonic Code has influenced the legal systems of more than 70 nations around the world. British historian Andrew Roberts states: "The ideas that underpin our modern world—meritocracy, equality before the law, property rights, religious toleration, modern secular education, sound finances, and so on—were championed, consolidated, codified and geographically extended by Napoleon. To them he added a rational and efficient local administration, an end to rural banditry, the encouragement of science and the arts, the abolition of feudalism and the greatest codification of laws since the fall of the Roman Empire".

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)

Nicholas II or Nikolai II Alexandrovich Romanov (18 May  1868 – 17 July 1918), known in the Russian Orthodox Church as Saint Nicholas the Passion-Bearer, was the last Tsar of Russia, ruling from 1 November 1894 until his forced abdication on 15 March 1917. His reign saw the fall of the Russian Empire from one of the foremost great powers of the world to economic and military collapse. His memory was reviled by Soviet historians as a weak and incompetent leader whose decisions led to military defeats and the deaths of millions of his subjects. By contrast Anglo-Russian historian Nikolai Tolstoy, leader of the International Monarchist League, says, "There were many bad things about the Tsar's regime, but he inherited an autocracy and his acts are now being seen in perspective and in comparison to the terrible crimes committed by the Soviets."

As Emperor, Nicholas gave limited support to the economic and political reforms promoted by top aides Sergei Witte and Pyotr Stolypin, but they faced too much aristocratic opposition to be fully effective. He supported modernization based on foreign loans and close ties with France, but resisted giving the new parliament (the Duma) major roles. He was criticised for the Khodynka Tragedy, antisemitic pogroms, Bloody Sunday, the violent suppression of the 1905 Russian Revolution, the repression of political opponents, and his perceived responsibility for defeat in the Russo-Japanese War (1904–1905), which saw the annihilation of the Russian Baltic Fleet at the Battle of Tsushima, the loss of Russian influence over Manchuria and Korea, and the Japanese annexation of the north of South Sakhalin Island.

Nicholas signed the Anglo-Russian Entente of 1907, which was designed to counter Germany's attempts to gain influence in the Middle East; it ended the Great Game of confrontation between Russia and the British Empire. He supported Serbia and approved the mobilization of the Russian Army on 30 July 1914. In response, Germany declared war on Russia on 1 August 1914 and its ally France on 3 August 1914, starting the First World War. The aristocracy was alarmed at the powerful influence of the despised peasant priest Grigori Rasputin over the tsar. The severe military losses led to a collapse of morale at the front and at home, leading to the fall of the House of Romanov in the February Revolution of 1917. Nicholas abdicated on behalf of himself and his son. With his family he was imprisoned by the Bolsheviks and executed in July 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.

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.

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".
