Matt Holzman, who produced shows including “The Business” and “The Document” for Los Angeles-area public radio station KCRW, died Sunday of lung cancer. He was 56.

Holzman was widely respected as a tireless booster of KCRW, a mentor and generous co-worker. A KCRW spokesperson said he died of stage 4 metastatic cancer, which was diagnosed at stage 4.

Born in Long Beach, Calif., he studied computer science at UC Santa Barbara and started out as a consultant before landing at the public radio powerhouse when it was a much smaller operation.

He launched the underwriting department that raised money for the station, presiding over the pledge drives with enthusiasm and humor. But he also wanted to tell stories, so he left the fundraising side.

As KCRW president Jennifer Ferro wrote on the KCRW website, “I remember when Matt fired himself from that job. He wanted to be a radio producer. So he quit and after a few days was rehired, at a much lower salary, to become an audio storyteller.”

In one of his early broadcast stories, Holzman talked about receiving a kidney transplant, which gave him a new lease on life and allowed him to travel.

A passionate movie lover, he was the first producer of “The Business,” KCRW’s weekly show about the entertainment industry. He also created the Matt’s Movies film screening series at which he interviewed directors and producers onstage.

Holzman was the founding producer of “Press Play” with Madeleine Brand, who remembered him in a tweet, saying, “He embodied the spirit of KCRW.”

A longtime lover of documentaries, Holzman created “The Document” podcast, interviewing prominent documentarians, and then turned the podcast into a documentary screening series.

Writer-producer and friend Jenni Konner remembered him on Instagram, saying, “Matt Holzman was one of the top humans. People climbed over each other to get the chair next to Matt at a dinner party. Matt was the most curious person I have met. He was warm. He was kind. He was so smart. If you’ve ever listened to KCRW, you’ve heard his voice asking you for money. He was so f—ing funny.”

“Matt loved life in a way few people do. He loved food and movies and LA and KCRW, and most of all, his large circle of friends. If he saw a movie he liked, he was relentless in getting people to see it. Same for a restaurant. Or an artist. Or a person. The people who knew and loved him are enriched by having had him in their lives. He was a joyous human being,” said his close friend and filmmaker Richard Shepard.

He is survived by sisters Stefanie, Janet and Lisa, and his partner Adria Kloke, who said, “He died peacefully and painlessly at home surrounded by love.”
