3. James “Jimmy” Nederlander and James L. Nederlander, The Nederlander Organization
The father-son duo own and operate nine theaters in New York and 15 other venues around the world, which makes the organization the second-largest theater syndicate of Broadway theaters. Both have made their mark on Broadway and national theater: Jimmy has produced more than 100 shows, and the National High School Musical Theater Awards are named the Jimmy Awards after him. His son is active in the theater community; he serves on the Broadway League Board of Governors as well as the Actors Fund board of trustees.
