Charles Émile Picard was a French mathematician who worked in algebraic geometry as well as elasticity, heat and electricity. He was born in Paris on 24 July 1856 and died there on 11 December 1941. His father, the manager of a silk factory, died during the siege of Paris in 1870, and his mother, the daughter of a medical doctor, had to find employment to support her two sons through their education. He studied at the Lycée Napoléon, later called the Lycée Henri IV, where he was a brilliant pupil in almost every subject, especially in translating Greek and Latin poetry, though he disliked mathematics at first.

The theorem was first established by Picard and Goursat using an iterative scheme: the basic idea is to prove a fixed point theorem using the contraction mapping theorem.
