Charles Atlas was a long-time resident of the Point who gained fame for his body-building business.

Wikipedia describes his career:

Charles Atlas, born Angelo Siciliano (October 30, 1892[1], Acri, Italy – December 23, 1972, Long Beach, New York[2]) was the developer of a bodybuilding method and its associated exercise program, most well-known for a landmark advertising campaign featuring his name and likeness, which has been described as one of the most lasting and memorable ad campaigns of all time.[3]

According to Atlas, he trained himself to develop his body from that of a "scrawny weakling", eventually becoming the most popular muscleman of his day. He took the name "Charles Atlas" after a friend told him he resembled the statue of Atlas on top of a hotel in Coney Island, and legally changed his name in 1922. His company, Charles Atlas Ltd., was founded in 1929 and, as of 2009, continues marketing a fitness program for the "97-pound weakling."

..."The Insult that Made a Man out of Mac"
In this, the full-length version, the protagonist, "Mac," is accosted on the beach by a sand-kicking bully while his date watches. Humiliated, the young man goes home and, after kicking a chair and gambling a ten-cent stamp, subscribes to Atlas's "Dynamic-Tension" program. Later, the now muscular protagonist goes back to the beach and beats up the bully, becoming the "hero of the beach." His girl returns, while other females marvel at how big his muscles are. (An earlier but otherwise almost identical version, "How Joe's Body Brought Him Fame Instead of Shame," debuted in the 1940s.
