Dr. Jules C. Stein was an American musician, physician, and business leader who built a band booking agency with $1,000 of capital into MCA Inc., a billion-dollar force in the world of mass entertainment. Stein's creation, MCA Inc. calls itself the world's largest producer of film entertainment. It produces and distributes television programs, distributes motion pictures, and produces and publishes works of music.
Stein was born in South Bend, Indiana and received degrees from the University of Chicago and Rush Medical College. He founded
the Music Corporation of America in 1924.
While attending college, Stein played the violin and saxophone to help finance his studies, and his success in arranging band dates led to his move from medicine to show business. He arranged one-night stands, instead of having bands seek engagements for whole seasons which was innovative and led to signing up Guy Lombardo and other top bands of the day. Next, he started package deals for complete shows for hotels and radio broadcasting.
