Black bottom pie is thought by some to be of Southern origin, the "black bottom" representing the dark, swampy lowlands along the Mississippi River; other sources have identified an origin in Louisiana or Oklahoma City in the early 1940s. Its invention has been claimed by Monroe Boston Strause of Los Angeles. Strause, who was known as the "Pie King", was the inventor of the chiffon pie and the graham cracker crust.
