Franklin Lyle (Frank) Bettger (1888-1981) was a salesman and self-help author. He was the father of longtime actor Lyle Bettger. He played Major League baseball with the St. Louis Cardinals in 1910 under the name Frank Betcher.

After his brief baseball career, Bettger returned to his native Philadelphia, where he started collecting accounts for a furniture store on a bike. He then started selling insurance, but was not successful and considered quitting after 10 months. Finally, Bettger succeeded and later became the author of the best-selling books How I Raised Myself from Failure to Success in Selling[1] and How I Multiplied My Income and Happiness in Selling.
