Life
Born in Warsaw, Zygmund obtained his PhD from Warsaw University (1923) and became a professor at Stefan Batory University at Vilnius (1930–39). In 1940, during the World War II occupation of Poland, he emigrated to the United States and became a professor at Mount Holyoke College in South Hadley. From 1945 until 1947 he was a professor at the University of Pennsylvania, and from 1947 at the University of Chicago.
He was a member of several scientific societies. From 1930 until 1952 he was a member of the Polish Society of Friends of Science (TNW), from 1946 a member of the Polish Academy of Learning (PAU), from 1959 a member of the Polish Academy of Sciences (PAN), and from 1961 a member of the National Academy of Science in Washington, D.C.. In 1986 he received the National Medal of Science.
His main interest was harmonic analysis. He wrote a standard two-volume work Trigonometric Series. His students included Alberto Calderón, Paul Cohen, Nathan Fine and Elias Stein. He died in Chicago.
His work has had a pervasive influence in many fields of mathematics, particularly in mathematical analysis. He wrote over 6 books. Perhaps most important was his work with Calderón on singular integral operators.
