Oakland was born in Brooklyn, New York,[2] the eldest of the three sons of immigrant Jewish parents, Jacob Weiss and Ethel Oaklander, born in Romania and the Russian Empire respectively.[3][4] His father was a plasterer and builder.[5] While he later claimed in media interviews to have been born in 1922[5][6] (a date repeated in his New York Times obituary),[1][7] Social Security and vital records indicate he was born Simon Weiss in 1915; his stage name was derived from his mother's maiden name, Oaklander.[8][9][10][Note 1]

He began his performing career as a musician (he was a violinist,[12] an avocation he pursued during his entire career as an actor). Oakland began his acting career in the late 1940s. He enjoyed a series of Broadway hits, including Light Up the Sky, The Shrike, and Inherit the Wind, and theater was one of his lasting passions. He was a concert violinist until the 1940s.[citation needed]
