Jacob "Jack" Isaacson was a sergeant in the New York City Police Department (NYPD) and Dolly was a homemaker. He was raised in The Bronx, where he attended DeWitt Clinton High School and was classmates with Judd Hirsch and Garry Marshall. By his mid-teens, due to his mother's influential personality, Isaacson had decided he wanted to be in show business.
Context: After leaving college, Isaacson formed a double act with his best friend Manny Glasser called "Donny and the Duke". The duo worked in local New York nightclubs for a few months before Isaacson was drafted into the US Army at age 21. He was commissioned as an officer and served in the artillery. While in the army he formed a double act with fellow soldier Murray Levine, Isaacson usually playing the comic while his partner was the straight man. The double act went on to win the All-Army entertainment contest and earned them an appearance on The Ed Sullivan Show in 1955.
