Robert Culp Dies, I Spy's Other Secret Agent Man

Actor who played Bill Cosby's partner on the 1960s series and the U.S. president in the Pelican Brief had a heart attack

Long before Phylicia Rashad came into the picture, it was Robert Culp who played Bill Cosby's other half.

Culp, who teamed with Cosby in the 1965-68 secret-agent series I Spy, died Wednesday after suffering a heart attack while on a walk near his Hollywood home. He was 79.

After finishing his run as tennis-playing lawman Kelly Robinson, the veteran character actor then starred in the adultery-run-amok dramedy Bob & Carol & Ted & Alice in 1969.

Though he's known to younger audiences today as Patricia Heaton's dad on Everybody Loves Raymond, but he made his mark on the small screen in a number of cop and crime-themed series, from I Spy to The Man From U.N.C.L.E. to Columbo to The Greatest American Hero, racking up four Emmy nominations and a Golden Globe nod along the way.

Culp is also a member of the club of actors who have played the president of the United States on the silver screen, having occupied the Oval Office in The Pelican Brief.
