Marcel Riesz (Hungarian: Riesz Marcell, pronounced [ˈriːs ˈmɒrt͡sɛlː]; 16 November 1886 – 4 September 1969) was a Hungarian-born mathematician, known for work on summation methods, potential theory, and other parts of analysis, as well as number theory, partial differential equations, and Clifford algebras. He spent most of his career in Lund (Sweden).
Marcel Riesz was born in Győr, Hungary (Austria-Hungary); he was the younger brother of the mathematician Frigyes Riesz. He obtained his PhD at Eötvös Loránd University under the supervision of Lipót Fejér. In 1911, he moved to Sweden upon the invitation of Gösta Mittag-Leffler. From 1911 to 1925 he taught at Stockholms högskola (now ). From 1926 to 1952 he was professor at Lund University. After retiring, he spent 10 years at universities in the United States. He returned to Lund in 1962, and died there in 1969.
Riesz was elected a member of the Royal Swedish Academy of Sciences in 1936.
The work of Riesz as a student of Fejér in Budapest was devoted to trigonometric series:
