Jacques François Mouret
Mouret often used a move now called the French Defense. He was one of the only players to use it and is one of the main reasons for it being called the French Defense. Mouret taught the move to players at the Café de la Régence. One of his students convinced the Paris team to use the defense in games played by letters against a London team. Following the victory of the French team, the opening quickly became known as the French Defense.
