Legall de Kermeur

Legall de Kermeur (1702 – 1792) was a French chess player.

Along with other famous players, he played in Paris's Café de la Régence, and is considered to have been possibly the strongest player in the world around the 1730s. He taught chess to François-André Philidor.

Legall is the eponym of Legall's mate, a mating pattern found in his only extant game, Legall-St Brie, Paris, 1750.
