Robert Wilson "Bob" Simmons (March 29, 1919 – September 26, 1954) was an American surfer and surfboard shaper, considered to be the father of the modern surfboard.
Simmons was born in Los Angeles, California. During his early teens, he developed a tumor on his left ankle which nearly caused his leg to be amputated. After beating the cancer, Bob was involved in a serious bicycle collision and, while staying in the hospital, he was advised to try surfing. He first got on a surfboard at age 20 at Newport Beach, California. In 1954, Simmons drowned while surfing at Windansea Beach in San Diego, California.
