Maurice Fréchet (September 2, 1878 – June 4, 1973) was a French mathematician.
In 1906, he introduced the concept of metric space, and was one of the founders of functional analysis. He also coined the term compact space. He was a student of Jacques Hadamard at École Normale Supérieure.
The Fréchet Distance is a metric function upon an infinite cartesian product of metric spaces <X1,d1>,<X2,d2>..., defined by:
