John Jowdy (1920-2013) was an American ten pin bowling coach and author[1] famous for developing the free armswing.
Before Jowdy started coaching, he ran several business ventures including the Tiffany Lounge in Houston Street, San Antonio.
[9] Jowdy made many contributions to the sport of bowling during his career of over 70 years, but the most notable was the free armswing used by the majority of contemporary professional bowlers.
In his book Bowling Execution, he emphasized the importance of synchronizing the pushback, swing and hand rotation with the four or five steps to the line.
Jowdy died in San Antonio on August 1, 2013 and was survived by his second wife Brenda, five children, 10 grandchildren, and five great-grandchildren.
