Robert Culp, the actor best known for his role in the TV series I Spy, died Wednesday after collapsing outside his Hollywood home. He was 79.

Culp became a star when he teamed with Bill Cosby in the racially groundbreaking I Spy from 1965 to 1968. He then went on to star in several movies, including Bob & Carol & Ted & Alice, The Castaway Cowboy, Golden Girl, Turk 182! and Big Bad Mama II.

Culp’s character in a 1964 episode of The Outer Limits, titled "Demon with a Glass Hand", inspired The Terminator.

Culp also starred on The Greatest American Hero as an FBI agent.  Bob’s more recent acting creds include a role on Everybody Loves Raymond.

Culp was married five times, to Nancy Ashe, Elayne Wilner, France Nuyen, Sheila Sullivan and Candace Culp. He had four children with Ashe and one with Candace Culp.
