Maurice Fréchet

Born on September 2, 1878, in Maligny, France, Maurice Fréchet became one of the mathematicians who helped open the door to modern abstract mathematics. He is especially known for being the first to define metric spaces, a basic idea that became central to topology and analysis.

He studied at the École Normale Supérieure and later taught at several universities, including the University of Strasbourg. Alongside his work in topology and functional analysis, he also contributed to probability and statistics, showing an unusual range across different parts of mathematics.

Fréchet lived a long life and remained an important figure in French mathematics across much of the twentieth century. He died on June 4, 1973, and is remembered for ideas that still sit near the foundations of higher mathematics.
