Gorshin's wife of 48 years, Christina, was at his side when he died Tuesday at Providence Saint Joseph Medical Center, his agent and longtime friend, Fred Wostbrock, said Wednesday.
"He put up a valiant fight with lung cancer, emphysema and pneumonia," Mrs. Gorshin said in a statement.
Despite dozens of television and movie credits — he worked steadily from the mid-1950s until just before his death, with two films listed as in production now — Gorshin will be forever remembered for his role as The Riddler, Adam West's villainous foil in the question mark-pocked green suit and bowler hat on "Batman" from 1966-69.
"It really was a catalyst for me," Gorshin recalled in a 2002 Associated Press interview. "I was nobody. I had done some guest shots here and there. But after I did that, I became a headliner in Vegas, so I can't put it down."
West said the death of his longtime friend was a big loss.
