William (Vilim) Feller "né" Vilibald Srećko Feller (
July 7 1906– January 14 1970), was a Croatian-American mathematicianspecializing in probability theory.
Early life and education
Feller was born in
Zagrebto Ida Oemichen-Perc, a Croatian-Austrian Catholic, and Eugene Victor Feller, who was born to a Polish Jewnamed David Feller and an Austrian Catholic named Elsa Holzer. [ [http://www.croatianhistory.net/etf/feller.html#eugen William Feller's Origins] ] Eugen was a famous chemist and created "Elsa fluid" named after his mother. According to Gian-Carlo Rota, Feller's father's surname was a "Slavic tongue twister", which William changed at the age of twenty [cite book

Roman Catholicmother for the saint day of his birthday. [MacTutor Biography|id=Feller|title=William Feller] In his school documentation, the small municipality of Donja Stubicain Zagorjeis mentioned. This is the birthplace of his father, who was an apothecaryand owner of a company producing hygienic utensils and cosmetics.
William finished his elementary and middle education in Zagreb, as well as two years of his math study. From 1925, he continued his study in
Göttingen, Germanywhere he gained the doctoral degree in 1926under the supervision of Richard Courant, with his work "Über algebraisch rektifizierbare transzendente Kurven".
Feller held a
docentposition at the University of Kielbeginning in 1928. Because he refused to sign a Nazi oath, [cite web

Copenhagen, Denmarkin 1933. He also lectured in Sweden( Stockholmand Lund). Finally, in 1939 he arrived in the U.S. where he became a citizenin 1944 and was on the faculty at Brown and Cornell. In 1950 he became a professor at Princeton University.
The works of Feller are contained in 104 papers and two books on a variety of topics such as
mathematical analysis, theory of measurement, functional analysis, geometry, and differential equations.
He was among the foremost probabilists outside of
Russia. In the middle of the 20th century, probability was not generally viewed as a fruitful area of researchin mathematics except in Russia, where Kolmogorovand others were influential. Feller contributed to the study of the relationship between Markov chains and differential equations. He wrote a two-volume treatise on probability that has since been universally regarded as one of the most important treatments of that subject.
Numerous topics relating to probability are named after him, including the
Feller process, Feller's explosion test, Feller-Brown movement, Feller propertyand Lindberg-Feller theorem. Books written by him and published as textbooks are considered invaluable in the popularisation of the theory of probability and among the best written during the 20th century.
Despite the fact that he spent the better part of his life out of
Croatiawhere he was born and grew up, and where he started his education, he was in touch with his relatives there, and with his colleagues at University of Zagreb, whom he sometimes visited and lectured. He received numerous awards and was an honoured member of numerous educational institutions (in Boston, Zagreb, London, Copenhagen).
Feller initiated the publication of the now well-known review journal "
