Antoni Zygmund (December 25, 1900 – May 30, 1992) was a Polish mathematician. He is considered one of the greatest analysts of the 20th century. His main area of interest was harmonic analysis.

Biography[edit]
Born in Warsaw, Zygmund obtained his Ph.D. from Warsaw University (1923) and became a professor at Stefan Batory University at Wilno (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 Warsaw Scientific Society (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 in Polish what soon became, in its English translation, the standard text in analysis, the two-volume Trigonometric Series. His students included Alberto Calderón, Paul Cohen, Nathan Fine, Józef Marcinkiewicz, Victor L. Shapiro, Guido Weiss, Elias Stein and Misha Cotlar. He died in Chicago.
His work has had a pervasive influence in many fields of mathematics, particularly in mathematical analysis. Perhaps most important was his work with Calderón on singular integral operators.[citation needed]
