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

1738 Died: Herman Boerhaave, Dutch botanist and physician (b. 1668)

Herman Boerhaave (31 December 1668 – 23 September 1738) was a Dutch botanist, chemist, Christian humanist, and physician of European fame. He is regarded as the founder of clinical teaching and of the modern academic hospital and is sometimes referred to as "the father of physiology," along with Venetian physician Santorio Santorio (1561–1636). Boerhaave introduced the quantitative approach into medicine, along with his pupil Albrecht von Haller (1708–1777) and is best known for demonstrating the relation of symptoms to lesions. He was the first to isolate the chemical urea from urine. He was the first physician to put thermometer measurements to clinical practice. His motto was Simplex sigillum veri: 'Simplicity is the sign of the truth'. He is often hailed as the "Dutch Hippocrates".

1913 – Roland Garros of France becomes the first to fly in an airplane across the Mediterranean (from St. Raphael in France to Bizerte, Tunisia).

Eugène Adrien Roland Georges Garros (6 October 1888 – 5 October 1918) was a French pioneering aviator and fighter pilot during World War I and early days of aviation. In 1928, the Roland Garros tennis stadium was named in his memory; the French Open tennis tournament takes the name of Roland-Garros from the stadium in which it is held.


On 23 September 1913 Roland Garros gained fame for making the first non-stop flight across the Mediterranean Sea from Fréjus-Saint Raphaël in the south of France to Bizerte in Tunisia in a Morane-Saulnier G. The flight commenced at 5:47 am and lasted nearly eight hours during which Garros had to solve two engine malfunctions. The following year, Garros joined the French army at the outbreak of World War I

1939 Died: Sigmund Freud, Austrian neurologist and psychiatrist (b. 1856)

Sigmund Freud (born Sigismund Schlomo Freud; 6 May 1856 – 23 September 1939) was an Austrian neurologist and the founder of psychoanalysis, a clinical method for treating psychopathology through dialogue between a patient and a psychoanalyst. 

Freud was born to Galician Jewish parents in the Moravian town of Freiberg, in the Austrian Empire. He qualified as a doctor of medicine in 1881 at the University of Vienna. Upon completing his habilitation in 1885, he was appointed a docent in neuropathology and became an affiliated professor in 1902. Freud lived and worked in Vienna, having set up his clinical practice there in 1886. In 1938, Freud left Austria to escape Nazi persecution. He died in exile in the United Kingdom in 1939.

In founding psychoanalysis, Freud developed therapeutic techniques such as the use of free association and discovered transference, establishing its central role in the analytic process. Freud's redefinition of sexuality to include its infantile forms led him to formulate the Oedipus complex as the central tenet of psychoanalytical theory. His analysis of dreams as wish-fulfillments provided him with models for the clinical analysis of symptom formation and the underlying mechanisms of repression. On this basis Freud elaborated his theory of the unconscious and went on to develop a model of psychic structure comprising id, ego and super-ego. Freud postulated the existence of libido, a sexualised energy with which mental processes and structures are invested and which generates erotic attachments, and a death drive, the source of compulsive repetition, hate, aggression and neurotic guilt. In his later works, Freud developed a wide-ranging interpretation and critique of religion and culture.

Though in overall decline as a diagnostic and clinical practice, psychoanalysis remains influential within psychology, psychiatry, and psychotherapy, and across the humanities. It thus continues to generate extensive and highly contested debate with regard to its therapeutic efficacy, its scientific status, and whether it advances or is detrimental to the feminist cause. Nonetheless, Freud's work has suffused contemporary Western thought and popular culture. W. H. Auden's 1940 poetic tribute to Freud describes him as having created "a whole climate of opinion / under whom we conduct our different lives."

August 31st in stamps de Bougainville, Baudelaire, Wilhelmina

Here are some events that happened on August 31st. It could be an event or a person that died or was born on that day

1811 Died: Louis Antoine de Bougainville, French admiral and explorer (b. 1729)

Louis-Antoine, Comte de Bougainville (12 November 1729 – 31 August 1811) was a French admiral and explorer. A contemporary of the British explorer James Cook, he took part in the Seven Years' War in North America and the American Revolutionary War against Britain. Bougainville later gained fame for his expeditions, including circumnavigation of the globe in a scientific expedition in 1763, the first recorded settlement on the Falkland Islands, and voyages into the Pacific Ocean. Bougainville Island of Papua New Guinea as well as the Bougainvillea flower were named after him.

In 1771, Bougainville published his travel log from the expedition under the title Le voyage autour du monde, par la frégate La Boudeuse, et la flûte L'Étoile (a.k.a. Voyage autour du monde and A Voyage Around the World). The book describes the geography, biology and anthropology of Argentina (then a Spanish colony), Patagonia, Tahiti and Indonesia (then a Dutch colony). The book was a sensation, especially the description of Tahitian society. Bougainville described it as an earthly paradise where men and women lived in blissful innocence, far from the corruption of civilization.

After an interval of several years, Bougainville again accepted a naval command and saw much active service between 1779 and 1782 during the American Revolutionary War, when France was as an ally of the rebels. He played a crucial part in the French victory at the Battle of the Chesapeake, which led to the eventual defeat of Great Britain.

Returning to Paris, he was one of the founding members of the Bureau des Longitudes. In 1799, the Consul Napoleon made him a senator. He died in Paris on 31 August 1811.

1867 Died: Charles Baudelaire, French poet and critic (b. 1821)

Charles Pierre Baudelaire (9 April 1821 – 31 August 1867) was a French poet who also produced notable work as an essayist, art critic, and pioneering translator of Edgar Allan Poe.

His most famous work, a book of lyric poetry titled Les Fleurs du mal (The Flowers of Evil), expresses the changing nature of beauty in the rapidly industrializing Paris during the mid-19th century. Baudelaire's highly original style of prose-poetry influenced a whole generation of poets including Paul Verlaine, Arthur Rimbaud and Stéphane Mallarmé, among many others. He is credited with coining the term "modernity" (modernité) to designate the fleeting, ephemeral experience of life in an urban metropolis, and the responsibility of artistic expression to capture that experience.

1880 Born: Wilhelmina, queen of the Netherlands (d. 1962)

Wilhelmina (Wilhelmina Helena Pauline Maria; 31 August 1880 – 28 November 1962) was Queen of the Netherlands from 1890 until her abdication in 1948. She reigned for nearly 58 years, longer than any other Dutch monarch. Her reign saw the First and the Second world wars, the Dutch economic crisis of 1933, and the decline of the Netherlands as a major colonial power.

Wilhelmina was the only child of King William III and his second wife, Emma of Waldeck and Pyrmont. On William's death in 1890, she ascended to the throne at the age of ten under the regency of her mother. In 1901, she married Duke Henry of Mecklenburg-Schwerin, with whom she had a daughter, Juliana. Wilhelmina was generally credited with maintaining Dutch neutrality during the First World War.

Following the German invasion of the Netherlands in 1940, Wilhelmina fled to Britain and took charge of the Dutch government-in-exile. She frequently spoke to the Dutch people over radio and came to be regarded as a symbol of the Dutch resistance. She returned to the Netherlands following its liberation in 1945.

Increasingly beset by poor health after the war, Wilhelmina abdicated in September 1948 in favour of Juliana. She retired to Het Loo Palace, where she died in 1962.

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

1635 Died: Lope de Vega, Spanish poet and playwright (b. 1562)

Lope Félix de Vega Carpio (25 November 1562 – 27 August 1635) was a Spanish playwright, poet, novelist and marine. He was one of the key figures in the Spanish Golden Age of Baroque literature. His reputation in the world of Spanish literature is second only to that of Miguel de Cervantes, while the sheer volume of his literary output is unequalled, making him one of the most prolific authors in the history of literature. He was nicknamed "The Phoenix of Wits" and "Monster of Nature" (in Spanish: Fénix de los Ingenios, Monstruo de la Naturaleza) by Cervantes because of his prolific nature.

Lope de Vega renewed the Spanish theatre at a time when it was starting to become a mass cultural phenomenon. He defined its key characteristics, and along with Pedro Calderón de la Barca and Tirso de Molina, took Spanish Baroque theatre to its greatest heights. Because of the insight, depth and ease of his plays, he is regarded as one of the greatest dramatists in Western literature, his plays still being produced worldwide. He was also considered one of the best lyric poets in the Spanish language, and wrote several novels. Although not well known in the English-speaking world, his plays were presented in England as late as the 1660s, when diarist Samuel Pepys recorded having attended some adaptations and translations of them, although he omits mentioning the author.

Some 3,000 sonnets, 3 novels, 4 novellas, 9 epic poems, and about 500 plays are attributed to him. Although he has been criticised for putting quantity ahead of quality, nevertheless at least 80 of his plays are considered masterpieces. He was a friend of the writer Francisco de Quevedo and an arch-enemy of the dramatist Juan Ruiz de Alarcón. The volume of his lifework made him envied by not only contemporary authors such as Cervantes and Luis de Góngora, but also by many others: for instance, Johann Wolfgang von Goethe once wished he had been able to produce such a vast and colourful oeuvre.

1908 Born: Lyndon B. Johnson, American commander and politician, 36th President of the United States (d. 1973)

Lyndon Baines Johnson (August 27, 1908 – January 22, 1973), often referred to by his initials LBJ, was an American politician who served as the 36th president of the United States from 1963 to 1969, and previously as 37th vice president from 1961 to 1963. He assumed the presidency following the assassination of President John F. Kennedy. A Democrat from Texas, Johnson also served as a United States Representative and as the Majority Leader in the United States Senate. Johnson is one of only four people who have served in all four federal elected positions. 

Born in a farmhouse in Stonewall, Texas, Johnson was a high school teacher and worked as a congressional aide before winning election to the US House of Representatives in 1937. Johnson won election to the United States Senate from Texas in 1948 after winning the Democratic Party's nomination by an incredibly narrow margin. He was appointed to the position of Senate Majority Whip in 1951. He became the Senate Minority Leader in 1953 and the Senate Majority Leader in 1955.

He became known for his domineering personality and the "Johnson treatment", his aggressive coercion of powerful politicians to advance legislation. Along with Speaker of the U.S. House of Representatives Sam Rayburn, Senate Majority Whip Earle Clements, and House Majority Whip Carl Albert, Johnson did not sign the 1956 Southern Manifesto drafted by Dixie South Democrats in the 84th U.S. Congress, despite all representing states where racial segregation of public schools had been legally required prior to the 1954 Brown v. Board of Education U.S. Supreme Court case. As Majority Leader, Johnson shepherded to passage the Civil Rights Acts of 1957 and 1960; the first civil rights bills passed by the U.S. Congress since the Reconstruction Era (1863–1877).

Johnson ran for the Democratic nomination in the 1960 presidential election. Although unsuccessful, he accepted the invitation of then-Senator John F. Kennedy of Massachusetts to be his running mate. They went on to win a close election over the Republican ticket of Richard Nixon and Henry Cabot Lodge Jr. On November 22, 1963, Kennedy was assassinated and Johnson succeeded him as president. The following year, Johnson won in a landslide, defeating Senator Barry Goldwater of Arizona. With 61.1 percent of the popular vote, Johnson won the largest share of the popular vote of any candidate since the largely uncontested 1820 election.

In domestic policy, Johnson designed the "Great Society" legislation to expand civil rights, public broadcasting, Medicare, Medicaid, aid to education, the arts, urban and rural development, public services and his "War on Poverty". Assisted in part by a growing economy, the War on Poverty helped millions of Americans rise above the poverty line during his administration. Civil rights bills that he signed into law banned racial discrimination in public facilities, interstate commerce, the workplace and housing; the Voting Rights Act prohibited certain requirements in southern states used to disenfranchise African Americans. With the passage of the Immigration and Nationality Act of 1965, the country's immigration system was reformed, encouraging greater immigration from regions other than Europe. Johnson's presidency marked the peak of modern liberalism after the New Deal era.

In foreign policy, Johnson escalated American involvement in the Vietnam War. In 1964, Congress passed the Gulf of Tonkin Resolution, which granted Johnson the power to use military force in Southeast Asia without having to ask for an official declaration of war. The number of American military personnel in Vietnam increased dramatically, from 16,000 advisors in non-combat roles in 1963 to 525,000 in 1967, many in combat roles. American casualties soared and the peace process stagnated. Growing unease with the war stimulated a large, angry anti-war movement based chiefly among draft-age students on university campuses.

Johnson faced further troubles when summer riots began in major cities in 1965 and crime rates soared, as his opponents raised demands for "law and order" policies. While Johnson began his presidency with widespread approval, support for him declined as the public became frustrated with both the war and the growing violence at home. In 1968, the Democratic Party factionalized as anti-war elements denounced Johnson; he ended his bid for renomination after a disappointing finish in the New Hampshire primary. Nixon was elected to succeed him, as the New Deal coalition that had dominated presidential politics for 36 years collapsed. After he left office in January 1969, Johnson returned to his Texas ranch, where he died of a heart attack at age 64, on January 22, 1973.

Johnson is ranked favorably by many historians because of his domestic policies and the passage of many major laws that affected civil rights, gun control, wilderness preservation, and Social Security, although he also drew substantial criticism for his escalation of the Vietnam War.

1965 Died:- Le Corbusier, Swiss-French architect and urban planner, designed the Philips Pavilion (b. 1887)

Charles-Édouard Jeanneret (6 October 1887 – 27 August 1965), known as Le Corbusier, was a Swiss-French architect, designer, painter, urban planner, writer, and one of the pioneers of what is now called modern architecture. He was born in Switzerland and became a French citizen in 1930. His career spanned five decades, and he designed buildings in Europe, Japan, India, and North and South America.

Dedicated to providing better living conditions for the residents of crowded cities, Le Corbusier was influential in urban planning, and was a founding member of the Congrès International d'Architecture Moderne (CIAM). Le Corbusier prepared the master plan for the city of Chandigarh in India, and contributed specific designs for several buildings there, specially the government buildings.

On 17 July 2016, seventeen projects by Le Corbusier in seven countries were inscribed in the list of UNESCO World Heritage Sites as The Architectural Work of Le Corbusier, an Outstanding Contribution to the Modern Movement.

Here are some events that happened on August 24th. It could be an event or a person that died or was born on that day

1540 Died: Parmigianino, Italian painter and etcher (b. 1503)

Girolamo Francesco Maria Mazzola (11 January 1503 – 24 August 1540), also known as Francesco Mazzola or, more commonly, as Parmigianino, was an Italian Mannerist painter and printmaker active in Florence, Rome, Bologna, and his native city of Parma. His work is characterized by a "refined sensuality" and often elongation of forms and includes Vision of Saint Jerome (1527) and the iconic if somewhat untypical Madonna with the Long Neck (1534), and he remains the best known artist of the first generation whose whole careers fall into the Mannerist period.

His prodigious and individual talent has always been recognized, but his career was disrupted by war, especially the Sack of Rome in 1527, three years after he moved there, and then ended by his death at only 37. He produced outstanding drawings, and was one of the first Italian painters to experiment with printmaking himself. While his portable works have always been keenly collected and are now in major museums in Italy and around the world, his two large projects in fresco are in a church in Parma and a palace in a small town nearby. This in conjunction with their lack of large main subjects has resulted in their being less well known than other works by similar artists. He painted a number of important portraits, leading a trend in Italy towards the three-quarters or full-length figure, previously mostly reserved for royalty.

1772 Born: William I of the Netherlands (d. 1840)

William I (Willem Frederik, Prince of Orange-Nassau; 24 August 1772 – 12 December 1843) was a Prince of Orange and the first King of the Netherlands and Grand Duke of Luxembourg.

He was the ruler of the Principality of Nassau-Orange-Fulda from 1803 until 1806 and of the Principality of Orange-Nassau in the year 1806 and from 1813 until 1815. In 1813 he proclaimed himself Sovereign Prince of the United Netherlands. He proclaimed himself King of the Netherlands and Duke of Luxembourg on 16 March 1815. In the same year on 9 June William I became also the Grand Duke of Luxembourg and after 1839 he was furthermore the Duke of Limburg. After his abdication in 1840 he styled himself King William Frederick, Count of Nassau.

1865 Born: Ferdinand I of Romania (d. 1927)

Ferdinand (Ferdinand Viktor Albert Meinrad; 24 August 1865 – 20 July 1927), nicknamed Întregitorul ("the Unifier"), was King of Romania from 1914 until 1927. Although a member of the Swabian branch of Germany's ruling House of Hohenzollern, Ferdinand sided against the Central Powers in World War I. Thus, at the war's end, Romania emerged as a much-enlarged kingdom, including Bessarabia, Bukovina and Transylvania, and Ferdinand was crowned king of "Greater Romania" in a grand ceremony in 1922. He died from cancer in 1927, succeeded by his grandson Michael under a regency.

Here are some events that happened on August 20th. It could be an event or a person that died or was born on that day

1901 Born: Salvatore Quasimodo, Italian novelist and poet, Nobel Prize laureate (d. 1968)

Salvatore Quasimodo (August 20, 1901 – June 14, 1968) was an Italian poet and translator.

In 1959 he won the Nobel Prize in Literature "for his lyrical poetry, which with classical fire expresses the tragic experience of life in our own times". Along with Giuseppe Ungaretti and Eugenio Montale, he is one of the foremost Italian poets of the 20th century.

Traditional literary critique divides Quasimodo's work into two major periods: the hermetic period until World War II and the post-hermetic era until his death. Although these periods are distinct, they are to be seen as a single poetical quest. This quest or exploration for a unique language took him through various stages and various modalities of expression.

As an intelligent and clever poet, Quasimodo used a hermetical, "closed" language to sketch recurring motifs like Sicily, religion and death. Subsequently, the translation of authors from Roman and Greek Antiquity enabled him to extend his linguistic toolkit. The disgust and sense of absurdity of World War II also had its impact on the poet's language. This bitterness, however, faded in his late writings, and was replaced by the mature voice of an old poet reflecting upon his world.

1912 Died: William Booth, English preacher, co-founded The Salvation Army (b. 1829)

William Booth (10 April 1829 – 20 August 1912) was an English Methodist preacher who, along with his wife, Catherine, founded The Salvation Army and became its first General (1878–1912). The Christian movement with a quasi-military structure and government founded in 1865 has spread from London, England, to many parts of the world and is known for being one of the largest distributors of humanitarian aid. In 2002, Booth was named among the 100 Greatest Britons in a BBC poll.

Having been founded as the East London Christian Mission in 1865, the name The Salvation Army developed from an incident in May 1878. William Booth was dictating a letter to his secretary George Scott Railton and said, "We are a volunteer army." Bramwell Booth heard his father and said, "Volunteer, I'm no volunteer, I'm a regular!" Railton was instructed to cross out the word "volunteer" and substitute the word "salvation". (The printer's proof copy of the Missions' report for 1878 declared "The Christian Mission Is A Volunteer Army", but the corrected proof read "The Christian Mission Is ... A Salvation Army") The Salvation Army was modelled after the military, with its own flag (or colours) and its own music, often with Christian words to popular and folkloric tunes sung in the pubs. Booth and the other soldiers in "God's Army" would wear the army's own uniform, 'putting on the armour,' for meetings and ministry work. He became the "General" and his other ministers were given appropriate ranks as "officers". Other members became "soldiers".

Though the early years were lean ones, with the need of money to help the needy an ever growing issue, Booth and The Salvation Army persevered. In the early 1880s, operations were extended to other countries, notably the United States, France, Switzerland, Sweden and others, including to most of the countries of the British Empire: Australia, Canada, India, Cape Colony, New Zealand, Jamaica, etc.

Often the beginnings in other countries occurred through "salvationist" activities by non-officers who had emigrated. With some initial success they would contact London to 'send officers.'

In other cases, like in Argentina, a non-salvationist told Booth that there were thousands of British people there who needed salvation. The four officers sent in 1890 found that those British were scattered all over the pampas. But the missionaries started ministry in the Spanish language and the work spread throughout the country – initially following the rail-road development, since the British in charge of building the rail-roads were usually sympathetic to the movement.

During his lifetime, William Booth established Army work in 58 countries and colonies, travelling extensively and holding, "salvation meetings."

1915 Died: Paul Ehrlich, German physician and academic, Nobel Prize laureate (b. 1854)

Paul Ehrlich (14 March 1854 – 20 August 1915) was a Nobel prize-winning German physician and scientist who worked in the fields of hematology, immunology, and antimicrobial chemotherapy. He is credited with finding a cure for syphilis in 1909. He invented the precursor technique to Gram staining bacteria. The methods he developed for staining tissue made it possible to distinguish between different types of blood cells, which led to the capability to diagnose numerous blood diseases.

His laboratory discovered arsphenamine (Salvarsan), the first effective medicinal treatment for syphilis, thereby initiating and also naming the concept of chemotherapy. Ehrlich popularized the concept of a magic bullet. He also made a decisive contribution to the development of an antiserum to combat diphtheria and conceived a method for standardizing therapeutic serums. 

In 1908, he received the Nobel Prize in Physiology or Medicine for his contributions to immunology. He was the founder and first director of what is now known as the Paul Ehrlich Institute.

1917 Died: Adolf von Baeyer, German chemist and academic, Nobel Prize laureate (b. 1835)

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

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

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

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

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

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

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

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

Here are some events that happened on August 19th. It could be an event or a person that died or was born on that day

1662 Died: Blaise Pascal, French mathematician, physicist, and philosopher (b. 1623)

Blaise Pascal (19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, writer and Catholic theologian. He was a child prodigy who was educated by his father, a tax collector in Rouen. Pascal's earliest work was in the natural and applied sciences, where he made important contributions to the study of fluids, and clarified the concepts of pressure and vacuum by generalising the work of Evangelista Torricelli. Pascal also wrote in defence of the scientific method.

In 1642, while still a teenager, he started some pioneering work on calculating machines. After three years of effort and 50 prototypes, he built 20 finished machines (called Pascal's calculators and later Pascalines) over the following 10 years, establishing him as one of the first two inventors of the mechanical calculator.

Pascal was an important mathematician, helping create two major new areas of research: he wrote a significant treatise on the subject of projective geometry at the age of 16, and later corresponded with Pierre de Fermat on probability theory, strongly influencing the development of modern economics and social science. Following Galileo Galilei and Torricelli, in 1647, he rebutted Aristotle's followers who insisted that nature abhors a vacuum. Pascal's results caused many disputes before being accepted.

In 1646, he and his sister Jacqueline identified with the religious movement within Catholicism known by its detractors as Jansenism. Following a religious experience in late 1654, he began writing influential works on philosophy and theology. His two most famous works date from this period: the Lettres provinciales and the Pensées, the former set in the conflict between Jansenists and Jesuits. In that year, he also wrote an important treatise on the arithmetical triangle. Between 1658 and 1659, he wrote on the cycloid and its use in calculating the volume of solids.

Throughout his life, Pascal was in frail health, especially after the age of 18; he died just two months after his 39th birthday.

1753 Died: Johann Balthasar Neumann, German engineer and architect, designed Basilica of the Fourteen Holy Helpers (b. 1687)

Johann Balthasar Neumann (27 January 1687 – 19 August 1753), usually known as Balthasar Neumann, was a German architect and military artillery engineer who developed a refined brand of Baroque architecture, fusing Austrian, Bohemian, Italian, and French elements to design some of the most impressive buildings of the period, including the Würzburg Residence and the Basilica of the Fourteen Holy Helpers (called Vierzehnheiligen in German).

The Würzburg Residence is considered one of the most beautiful and well proportioned palaces in Europe and the Basilica of the Fourteen Holy Helpers is considered by some as the crowning work of the period.

German stamps depicting Johann Balthasar Neumann

1871 Born: Orville Wright, American engineer and pilot, co-founded the Wright Company (d. 1948)

The Wright brothers—Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912)—were two American aviation pioneers generally credited with inventing, building, and flying the world's first successful motor-operated airplane. They made the first controlled, sustained flight of a powered, heavier-than-air aircraft with the Wright Flyer on December 17, 1903, 4 mi (6 km) south of Kitty Hawk, North Carolina. In 1904–05, the brothers developed their flying machine to make longer-running and more aerodynamic flights with the Wright Flyer II, followed by the first truly practical fixed-wing aircraft, the Wright Flyer III. The Wright brothers were also the first to invent aircraft controls that made fixed-wing powered flight possible.

The brothers' breakthrough was their creation of a three-axis control system, which enabled the pilot to steer the aircraft effectively and to maintain its equilibrium. This method remains standard on fixed-wing aircraft of all kinds.  From the beginning of their aeronautical work, the Wright brothers focused on developing a reliable method of pilot control as the key to solving "the flying problem". This approach differed significantly from other experimenters of the time who put more emphasis on developing powerful engines. Using a small home-built wind tunnel, the Wrights also collected more accurate data than any before, enabling them to design more efficient wings and propellers.  Their first U.S. patent did not claim invention of a flying machine, but a system of aerodynamic control that manipulated a flying machine's surfaces. 

The brothers gained the mechanical skills essential to their success by working for years in their Dayton, Ohio-based shop with printing presses, bicycles, motors, and other machinery. Their work with bicycles, in particular, influenced their belief that an unstable vehicle such as a flying machine could be controlled and balanced with practice. From 1900 until their first powered flights in late 1903, they conducted extensive glider tests that also developed their skills as pilots. Their shop employee Charlie Taylor became an important part of the team, building their first airplane engine in close collaboration with the brothers.

The Wright brothers' status as inventors of the airplane has been subject to counter-claims by various parties. Much controversy persists over the many competing claims of early aviators. Edward Roach, historian for the Dayton Aviation Heritage National Historical Park, argues that they were excellent self-taught engineers who could run a small company, but they did not have the business skills or temperament to dominate the growing aviation industry.

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

1769 Born: Napoleon, French general and emperor (d. 1821)

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".

1824 – The Marquis de Lafayette, the last surviving French general of the American Revolutionary War, arrives in New York and begins a tour of 24 states.

Marie-Joseph Paul Yves Roch Gilbert du Motier, Marquis de Lafayette (6 September 1757 – 20 May 1834), known in the United States simply as Lafayette, was a French aristocrat and military officer who fought in the American Revolutionary War, commanding American troops in several battles, including the Siege of Yorktown. After returning to France, he was a key figure in the French Revolution of 1789 and the July Revolution of 1830.

Lafayette was born into a wealthy land-owning family in Chavaniac in the province of Auvergne in south central France. He followed the family's martial tradition and was commissioned an officer at age 13. He became convinced that the American revolutionary cause was noble, and he traveled to the New World seeking glory in it. He was made a major general at age 19, but he was initially not given American troops to command. He was wounded during the Battle of Brandywine but still managed to organize an orderly retreat, and he served with distinction in the Battle of Rhode Island. In the middle of the war, he sailed for home to lobby for an increase in French support. He returned to America in 1780 and was given senior positions in the Continental Army. In 1781, troops under his command in Virginia blocked forces led by Cornwallis until other American and French forces could position themselves for the decisive Siege of Yorktown.

Lafayette returned to France and was appointed to the Assembly of Notables in 1787, convened in response to the fiscal crisis. He was elected a member of the Estates General of 1789, where representatives met from the three traditional orders of French society: the clergy, the nobility, and the commoners. After forming the National Constituent Assembly, he helped to write the Declaration of the Rights of Man and of the Citizen with Thomas Jefferson's assistance. This document was inspired by the United States Declaration of Independence and invoked natural law to establish basic principles of the democratic nation-state. He also advocated the end of slavery, in keeping with the philosophy of natural liberty. After the storming of the Bastille, he was appointed commander-in-chief of France's National Guard and tried to steer a middle course through the years of revolution. In August 1792, radical factions ordered his arrest, and he fled into the Austrian Netherlands. He was captured by Austrian troops and spent more than five years in prison.

Lafayette returned to France after Napoleon Bonaparte secured his release in 1797, though he refused to participate in Napoleon's government. After the Bourbon Restoration of 1814, he became a liberal member of the Chamber of Deputies, a position which he held for most of the remainder of his life. In 1824, President James Monroe invited him to the United States as the nation's guest, and he visited all 24 states in the union and met a rapturous reception. During France's July Revolution of 1830, he declined an offer to become the French dictator. Instead, he supported Louis-Philippe as king, but turned against him when the monarch became autocratic. He died on 20 May 1834 and is buried in Picpus Cemetery in Paris, under soil from Bunker Hill. He is sometimes known as "The Hero of the Two Worlds" for his accomplishments in the service of both France and the United States.

1883 Born: Ivan Meštrović, Croatian sculptor and architect (d. 1962)

Ivan Meštrović (15 August 1883 – 16 January 1962) was a renowned Yugoslavian and Croatian sculptor, architect and writer of the 20th century.

He was the most prominent sculptor of Croatian modern sculpture and a leading personality of artistic life in Zagreb. He studied at the Pavle Bilinić's Stone Workshop in Split and at the Academy of Fine Arts Vienna, where he was formed under the influence of the Secession. He traveled throughout Europe and studied the works of ancient and Renaissance masters, especially Michelangelo, and French sculptors A. Rodin, A. Bourdelle and A. Maillola. He was the initiator of the national-romantic group Medulić (he advocated the creation of art of national features inspired by the heroic folk songs). During the First World War, he lived in emigration. After the war, he returned to Croatia and began a long and fruitful period of sculpture and pedagogical work. In 1942 he emigrated to Italy, in 1943 to Switzerland and in 1947 to the United States. He was a professor of sculpture at the Syracuse University and from 1955 at the University of Notre Dame in South Bend, Indiana.

Most of his early works of symbolic themes were formed in the spirit of the Secession, some of which, like the Well of Life, show impressionist restless surfaces created under the influence of Rodin's naturalism, and the second, reviving national myth, become stylized monumental plastics (Kosovo cycle, 1908-1910). Before the First World War, he left pathetic epic stylization, expressing increasingly emotional states, as evidenced by the wooden reliefs of biblical themes made in a combination of Archaic, Gothic, Secessionist and Expressionist styles. During the 1920s and 1930s, the classical component prevailed in his works. In this period, he created a number of public monuments of strong plastic expression, pronounced and legible shapes (Grgur Ninski and Marko Marulić in Split, Andrija Medulić, Andrija Kačić-Miošić and Josip Juraj Strossmayer in Zagreb, The Bowman and The Spearman in Chicago). Portraits take a special place in his opus.

Meštrović achieved works of strong plastic value in the construction-sculptural monuments and projects, mostly with central layout (the Mausoleum of the Račić family in Cavtat, the Mausoleum of the Meštrović family in Otavice, the Meštrović Pavilion in Zagreb, Monument to the Unknown Hero in Belgrade). He also designed a memorial church of King Zvonimir in Biskupija near Knin inspired by old Croatian churches, a representative family palace, today the Ivan Meštrović Gallery, and reconstructed renaissance fortified mansion Crikvine-Kaštilac in Split.
