Mathematician

Rene Frechet

Modern

Rene Maurice Frechet was a French mathematician, born on 2 September 1878 and died on 4 June 1973. He made major contributions to general topology and was the first to define metric spaces. He also made several important contributions to statistics and probability, as well as to calculus. His dissertation opened the entire field of functionals on metric spaces and introduced the notion of compactness. Independently of Riesz he discovered the representation theorem in the space of Lebesgue square integrable functions, and he is often called the founder of the theory of abstract spaces.
