Early life Prosky, a Polish American, was born in the Manayunk neighborhood of Philadelphia, Pennsylvania, to Helen (Kuhn) and Joseph Porzuczek. His father was a grocer and butcher. He was raised in a working-class neighborhood and studied at the American Theatre Wing, later graduating from Temple University. He performed at Old Academy Players, a small theater in the East Falls section of Philadelphia, adjacent to Manayunk. He also served in the U.S. Air Force during the Korean War, but got a hardship discharge to help with the family store when his father died suddenly.
