Rosen and his family moved to Miami, FL when he was three years old due to his asthma. He grew up in the southwest section of Miami, which is now the heart of Little Havana. He attended the University of Florida in the September session of 1941–42, where he played third base for the Gators. Rosen also attended Florida Military Academy in St. Petersburg, FL.
