Fans of Peyton Place and Buck Rogers in the 25th Century remember Tim O'Connor best for his prominent roles on both of those shows, but in the 20-year span between those parts, he also featured in all of our favorite classic shows.

As a character actor, he made a mark with recurring guest roles on long-running series like M*A*S*H, Hawaii Five-O and Columbo. Some of our favorite appearances include early parts on Gunsmoke and The Outer Limits in the 1960s. His dark features gave him the distinct look of a leading man, which made him the perfect choice for a range of characters, from cowboys to aliens.
