A veteran television executive and philanthropist who had a hand in a string of hit TV series has died. Variety reports that Peter Grad, the former president of MTM Television, died Saturday of a heart attack while on vacation in Vail, Colo. He was 75.

Grad led MTM for five years, from 1987-1992, and also had a seven-year run as a development executive at 20th Century Fox. He was behind a number of high-profile series including “L.A. Law” and “The Fall Guy.”

“Grad was married for 47 years to Laurie Burrows Grad, daughter of famed playwright-director Abe Burrows. He was the father of Nick Grad, president of original programming and production at FX Networks,” Variety notes.

In recent years Grad, a New Jersey native, worked on behalf of the Alzheimer’s Association.

“As a tribute to his late father-in-law, Peter and Laurie Grad launched and co-chaired the Alzheimer’s Assn.’s annual A Night at Sardi’s fundraiser, which recognizes researchers, doctors, caregivers and families affected by the neurological disease,” the Variety report notes. “The event has generated $27 million in donations over the past 23 years and has garnered the support of a host of stage, TV and film stars who perform songs from Broadway musicals.”
