Barney Martin, the man who played Jerry's dad on Seinfeld for all but one episode, died at age 82 earlier this week. Gothamist never knew that he was a former NYC detective, as we knew him mainly as a Florida retiree who would overreact at whatever his bachelor son in NYC would do. And who knew he originated the role of cuckolded Amos Hart in Chicago - the same production with Jerry Orbach?
A nice description of Morty Seinfeld's character on Stan the Caddy. Here's a list of all the Seinfeld episodes he was in. And Barney, Gothamist will de-belt our trench and goes beltless for you.
