Tim Donnelly

Who is Tim Donnelly?

Timothy David "Tim" Donnelly is an American actor and director, and is the younger brother of Jack Webb's stock director Dennis Donnelly. He had supporting roles in episodes of Webb-produced shows, such as Dragnet and Adam-12, before landing the role that made him famous, that of Firefighter Chester B. "Chet" Kelly, in the Mark VII television series Emergency!

Donnelly appeared in several other series outside of those by Mark VII. He starred in episodes of television series such as Vega$, Hawaii Five-O, The Virginian, B. J. and the Bear, Enos and The A-Team, and even had starring roles in films such as The Clonus Horror and The Toolbox Murders. He had an uncredited role as a 13-year-old Baby Face Nelson, in the 1957 movie of the same name. He left acting in 1984, but appears at Emergency! conventions. It was Donnelly's idea, in 1973, that his Emergency! character of Chet should grow a moustache, and therefore, Donnelly grew a very bushy moustache so that his character could stand out from the others; this soon became his character's trademark. He directed several episodes of Emergency! during its seven-year run.
