Stefan Bergman

Stefan Bergman (5 May 1895 – 6 June 1977) was a Congress of Poland-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. Provided by Wikipedia
