Howard Rothberg, formerly an agent and personal manager for Mel Brooks and Larry Gelbart, among others, died of cancer in Los Angeles on Jan. 17. He was 72.

Rothberg was an associate producer on “The Smothers Brothers Comedy Hour” in the late 1960s, and then became an agent at ICM (formerly CMA), where he worked in the motion picture department with mentor David Begelman.

In the mid-1970s he founded his own personal management business, handling Brooks, Gelbart, Dom DeLuise and Anne Bancroft; he also developed feature film projects with Sid Caesar.

Rothberg ultimately changed direction to pursue ventures in the emerging personal computer industry.

The Chicago native graduated from the U. of Illinois with degrees in finance and marketing. He served in the Air Force Reserve and worked as a stockbroker before relocating to Los Angeles in 1969.

Rothberg is survived by life partner Dina Gribben; a son and a daughter; a sister; and ex-wife Darryle Pollack. A memorial site has been created on Legacy.com, and a tribute to Howard’s life is planned by family and friends to take place this spring.
