Leonhard Euler
Leonhard Euler ( , ; 15 April 170718 September 1783) was a Swiss mathematician, physicist, astronomer, geographer, logician and engineer who founded the studies of graph theory and topology and made pioneering and influential discoveries in many other branches of mathematics such as analytic number theory, complex analysis, and infinitesimal calculus. He introduced much of modern mathematical terminology and notation, including the notion of a mathematical function. He is also known for his work in mechanics, fluid dynamics, optics, astronomy and music theory. Euler is held to be one of the greatest mathematicians in history and the greatest of the 18th century. A statement attributed to Pierre-Simon Laplace expresses Euler's influence on mathematics: "Read Euler, read Euler, he is the master of us all." Carl Friedrich Gauss remarked: "The study of Euler's works will remain the best school for the different fields of mathematics, and nothing else can replace it." Euler is a ...

Carl Euler
Carl Hieronymus Euler (1834–27 November 1901) was a Swiss farmer and ornithologist who worked in Brazil. Euler was born in Basel, Switzerland. In 1853 he travelled to Rio de Janeiro and married a widow, Madeleine Guerrini-Girrard (1822-1904), who owned a large farm near Cantagalo. He also became Swiss vice-consul, and in his spare time collected birds and studied their habits. His findings were published in the '' Journal für Ornithologie'' between 1867 and 1893. He sent his specimens to the Museum für Naturkunde in Berlin, where Jean Cabanis named Euler's flycatcher Euler's flycatcher (''Lathrotriccus euleri'') is a small passerine bird in the tyrant flycatcher family. It breeds in South America east of the Andes from Colombia and Venezuela south to Bolivia and Argentina, and on the islands of Trinidad and ... (''Lathrotriccus euleri'') after him, and to the National Museum of Brazil. He died in Rio de Janeiro on 27 November 1901. References * * Swiss ornithol ...

Hans Heinrich Euler
Hans Heinrich Euler (b. 6 October 1909 in Merano, d. 1941) was a German physicist. He received his PhD in 1935 at the University of Leipzig under Werner Heisenberg with a thesis ''Über die Streuung von Licht an Licht nach der Diracschen Theorie'' (On the scattering of light by light based on Dirac's theory). Euler was the first physicist who was able to show that Paul Dirac's introduction of the positron opens the possibility that photons in electron-positron pair production scatter with each other and calculated the cross section for this process in his PhD thesis. Based on the observations of Helmuth Kulenkampff, Euler and Heisenberg were able to calculate an improved figure for meson decay time. They also introduced the Euler–Heisenberg Lagrangian that laid the basis for the quantitative treatment of vacuum polarization. Euler died in a reconnaissance flight over the Sea of Azov, during World War II. He had joined the Luftwaffe a few months earlier. Publications by H ...

Johann Euler
Johann Albrecht Euler (27 November 1734 – 17 September 1800) was a Swiss-Russian astronomer and mathematician. Also known as ''Johann Albert Euler'' or ''John-Albert Euler'', he was the first child born to the great Swiss mathematician Leonhard Euler (1707–1783), who had emigrated or the first timeto Saint-Petersburg on 17 May 1727. His mother was Katharina Gsell (1707–1773) whose maternal grandmother was the famous scientific illustrator Maria Sibylla Merian (1647–1717) and whose father was the Swiss Baroque painter Georg Gsell (1673–1740) who had emigrated to Russia in 1716. Katharina married Leonhard Euler on 7 January 1734 and Johann Albert would be the eldest of their 13 children (only 5 of whom survived childhood). In 1754 he became a member of the Berlin Academy. In 1758, he served briefly as director of the Astronomical Calculation Institute (ARI). On Euler's return to St. Petersburg in 1765, he was appointed as the chair of physics at the St. Petersburg ...

Ulf Von Euler
Ulf Svante von Euler (7 February 1905 – 9 March 1983) was a Swedish physiologist and pharmacologist. He shared the Nobel Prize in Physiology or Medicine in 1970 for his work on neurotransmitters. Life Ulf Svante von Euler-Chelpin was born in Stockholm, the son of two noted scientists, Hans von Euler-Chelpin, a professor of chemistry, and Astrid Cleve, a professor of botany and geology. His father was German and the recipient of Nobel Prize for Chemistry in 1929, and his maternal grandfather was Per Teodor Cleve, Professor of Chemistry at the Uppsala University, and the discoverer of the chemical elements thulium and holmium. Enjoying such a privileged family environment in science, education and research, it is not surprising that young Ulf would become a scientist, too, so he went to study medicine at the Karolinska Institute in 1922. At Karolinska, he worked under Robin Fåhraeus in blood sedimentation and rheology and did research work on the pathophysiology of vasoconstr ...

Hans Von Euler-Chelpin
Hans Karl August Simon von Euler-Chelpin (15 February 1873 – 6 November 1964) was a German-born Swedish biochemist. He won the Nobel Prize in Chemistry in 1929 with Arthur Harden for their investigations on the fermentation of sugar and enzymes. He was a professor of general and organic chemistry at Stockholm University (1906–1941) and the director of its Institute for organic-chemical research (1938–1948). Euler-Chelpin was distantly related to Leonhard Euler. He married chemist Astrid Cleve, the daughter of the Uppsala chemist Per Teodor Cleve. In 1970, their son Ulf von Euler, was awarded the Nobel Prize in Physiology or Medicine. Personal life von Euler-Chelpin was born on 15 February 1873 at Augsburg, Germany to Rigas Georg Sebastian von Euler-Chelpin and Gabriele von Euler-Chelpin (née Furtner). His father was a captain in the Royal Bavarian Regiment, who was soon transferred to Munich. During his childhood, he spent most of his time with his grandmother at Wass ...
