He was initially educated in Warsaw. In 1919, he went to Kharkov, Ukraine and spent one year as a student of the Russian mathematician Bernstein. In 1920, he emigrated to France and settled in Paris. In subsequent years, he attended the seminars of Hadamard, Lebesgue, Picard, and others. In 1923, he received a doctorate from Paris-Sorbonne University on the theory of analytic continuation of Taylor series. His Ph.D. Advisor was Hadamard. In 1924, he was awarded a Rockefeller Fellowship and spent almost two years in the United States. In 1926, he received the French nationality. In 1926-27, he spent one year as Assistant Professor at Rice Institute (now Rice University) in Houston, Texas.

One of them, his nephew Benoit Mandelbrot, was to discover the Mandelbrot set and coin the name fractal in the 1970s. In 1938, he succeeded Hadamard at Collège de France and took up the Chair of Analytical Mechanics and Celestial Mechanics.〔(Professeurs disparus ) at Collège de France.〕 In 1939, he fought for France when the country was invaded by the Nazis. In 1940, as many scientists helped by Louis Rapkine and the Rockefeller Foundation, he relocated to the United States and took up a position at Rice Institute.
