Frank Simmons Leavitt (June 30, 1891 – May 29, 1953) was an American professional wrestler of the early 1900s, known by the ring name Man Mountain Dean.

Although he played guard and center for the New York Brickley Giants of the National Football League (NFL) in 1921,[2] he concentrated most of his efforts on professional wrestling.

He competed in the ring for a time under the name "Hell's Kitchen Bill-Bill" (a "hillbilly" reference which was suggested to him by the writer Damon Runyon) but eventually settled on the moniker of "Stone Mountain".

[1] After a successful wrestling tour of Germany which had been booked by his wife, Doris Dean, he was invited to take a job in the UK as stunt-double for Charles Laughton in the movie The Private Life of Henry VIII.

Meanwhile, he continued a successful wrestling career, participating altogether in 504 professional bouts[4]; he commanded fees of upwards of $1,500 for each match.

Dean and his life story was featured in the June 2022 edition of Sports Illustrated under the title "The Classified Case of the Pro Wrestler Who Helped Beat the Nazis" and primarily examined his time as a trainer at Camp Ritchie.
