Born Norman Adelberg in 1924, he served in the Army during World War II. At the end of the conflict he had the opportunity to benefit from the GI Bill program meant to help returning soldiers to start or resume studying. That is how, while attending Texas Christian University, he discovered on the boards of on-campus theater that he had a talent for acting. This was the beginning of a long, long career. Though most of the time in small or even bit parts, Alden, worked for such big names as Howard Hawks, Jerry Lewis, Walt Disney, Woody Allen and Tim Burton. He might have become a major star himself after Richard C. Sarafian chose him for the title role of Andy (1965). The director must have been very pleased with Alden for, as Andy Chadakis - the retarded son of elderly Greek immigrants - he showed remarkable acting ability . Unfortunately, the film was little seen and the gifted actor landed no other parts of such importance and quality afterward.
