||Captain François Mingaud (born 4 January 1771) was an infantry officer in the French army and a carom billiards player. He is credited as the inventor of the leather tip for a billiards cue, a "possibly not original idea" that he perfected while imprisoned in Bicêtre (now Bicêtre Hospital) for political outspokenness. This revolutionized the game of billiards, allowing the cue ball to be finely manipulated by the application of spin. Pic. | |||
