Wayman Crow McCreery (June 14, 1851 –1901) was a real estate agent, opera composer, and the internal revenue collector of St. Louis, Missouri. He is best known as the popularizer and possible inventor of three-cushion billiards. Playwright Augustus Thomas' wrote of him in 1922: The very first tournament at three-cushion billiards took place January 14–31, 1878, in C. E. Mussey's Room in St. Louis. McCreery played in the tourney, which was won by New Yorker Leon Magnus. The high run for the tournament was just 6 points, and the high average a .75.
