After college, he entered eight AAU tournaments – and won all of them. In an era where many people inflate their numbers, Wittenberg legitimately won over 300 straight matches. He won a Gold medal at the 1948 London Olympics and came back to win Silver in 1952 at Helsinki. He doesn’t have any World Championships to his credit because his employer, The New York Police Department, would not allow him the time off.
One of the notable things about Wittenberg is that he was one of the few athletes at the time who actively lifted weights. His coaches at the time forbade him to do so, but Wittenberg understood how important it was and would not hear of it. They gave in and allowed him to keep lifting weights so as long as he didn’t let it be known.
Later on, he wrote this book on Isometrics which has gone through five printings.
