Marty Feldman
From Muppet Wiki
Marty Feldman (1933-1982), best remembered as Igor in Young Frankenstein, was the guest star on The Muppet Show episode 518.
When Meredith Vieira assembled a puppet from the Muppet Whatnot Workshop incorrectly on The Today Show, with eyes pointing outwards, Kermit described it as "a Marty Feldman Whatnot".
Feldman died on December 2, 1982 in Mexico City of a massive heart attack following food poisoning from eating shellfish while filming the movie Yellowbeard. Ironically, he was in the midst of filming a scene in which his character was supposed to die. (A stand-in completed the scene.)
