Stefan Bergman


Stefan Bergman (5 May 1895 – 6 June 1977) was a Polish-born American mathematician whose primary work was in complex analysis. His name is also written Bergmann; he dropped the second "n" when he came to the U. S. He is best known for the kernel function he discovered while at Berlin University in 1922. This function is known today as the Bergman kernel. Bergman taught for many years at Stanford University, and served as an advisor to several students.

Born in , Congress Poland, Russian Empire, Bergman received his Ph.D. at Berlin University in 1921 for a dissertation on Fourier analysis. His advisor, Richard von Mises, had a strong influence on him, lasting for the rest of his career. In 1933, Bergman was forced to leave his post at the Berlin University because he was a Jew. He fled first to Russia, where he stayed until 1939, and then to Paris. In 1939, he emigrated to the United States, where he would remain for the rest of life. He was elected a Fellow of the American Academy of Arts and Sciences in 1951. He was a professor at Stanford University from 1952 until his retirement in 1972. He was an invited speaker at the International Congress of Mathematicians in 1950 in Cambridge, Massachusetts and in 1962 in (On meromorphic functions of several complex variables). He died in Palo Alto, California, aged 82.
