Breaking new ground on television in the 1970s and '80s by tackling timely social issues of the day, this Emmy-nominated medical drama routinely placed intrepid Los Angeles coroner Dr. Quincy (Jack Klugman) in the midst of seemingly unsolvable cases. The show's roster of celebrity guest stars over the years grew to include -- among others -- Jamie Lee Curtis, Dabney Coleman, Kim Cattrall, Buddy Hackett, June Lockhart and Joan Van Ark.
