Ralston Burdett Hemsley (June 24, 1907 – July 31, 1972) was a professional baseball catcher. Born in Syracuse, Ohio, he played 19 seasons in Major League Baseball. He was nicknamed “Rollicking Rollie”.
Hemsley was known for having a drinking problem, one which caused him to be kicked off four separate clubs. Hemsley would later attend Alcoholics Anonymous meetings to help himself sober up. He revealed his membership to the press in 1940, becoming the first AA member to break their anonymity on a national level. Hemsley’s anonymity break was one of the first developments to raise questions and concern about personal anonymity in the organization.
