Martin Milner, who starred on TV on “Adam-12” with Kent McCord and, earlier, on “Route 66” with George Maharis, died Sunday night, Diana Downing, a representative for his fan page, confirmed. He was 83.

Milner was also known for his roles as a jazz guitarist in the brilliant 1957 film “Sweet Smell of Success” and in the 1967 camp classic “Valley of the Dolls.”

Milner began acting in movies while a teen, after his father got him an agent, first appearing in the 1947 classic “Life with Father.” The film starred William Powell and Irene Dunne, and thus Milner, along with his co-star Elizabeth Taylor, bridged the generations in Hollywood between the golden age and contemporary era.

He appeared as Officer Pete Molloy alongside Kent McCord’s Officer Jim Reed in NBC’s “Adam-12” from 1968-75. Molloy was the seasoned, savvy veteran bringing along Reed who was, at first, a rookie.

The innovative series had a more realistic quality than previous cop shows: The partners, on which the show narrowly focused, would patrol with no idea what they would encounter through the course of the day, and viewers got to witness the highs and lows in their lives.

After he stopped acting, he co-hosted a radio show in Southern California, “Let’s Talk HookUp,” about freshwater and saltwater fishing, for a number of years. In the early 1970s he bought a 24-acre avocado farm where he lived with his family.

Survivors include Milner’s wife, Judith Bess “Judy” Jones, a former singer and actress to whom he had been married since 1957; daughter Molly; and sons Stuart and Andrew. Daughter Amy, who appeared in an episode of “Adam-12,” died of acute myeloid leukemia in 2004.
