Don Larsen, pitcher for the Yankees and the only man ever to pitch a perfect game in a World Series. ESPN.
Jack “Only A Bill” Sheldon. Mark Evanier has a nice tribute up at his blog, with two funny stories about the late Mr. Sheldon (who, in addition to his “Schoolhouse Rock” work, did several appearances on the late 60’s/early 70s “Dragnet”).
Martin West. He did bit parts on a lot of stuff, including “Ironside”, “The Invaders”, and “Hill Street Blues”.
(Hattip on all three of these to Lawrence.)
For the historical record: David Stern. ESPN. Field of Schemes.
