You know that show you loved when you were a kid? Chances are this guy came up with it. The mastermind behind The A-Team, 21 Jump Street and The Rockford Files owned television in the '70s and '80s, ultimately having a hand in the creation of 40 TV shows and plus general involvement in many more. Known for his iconic typewriter-tapping logo (followed by a flourish of pulling out and tossing the page to form a "C") at the end of episodes, the writer and producer married his childhood sweetheart and had four children, though one child would die in a beach accident. Later in life, he turned to writing crime novels and saw several TV projects turned into feature films.
