Russell Johnson, who played Professor Roy Hinkley on the beloved '60s comedy series "Gilligan's Island," has died at 89.
The actor's wife, Constance, confirms that he died of kidney failure early this morning.
His agent, Michael Eisentstadt, also confirmed the actor's death and said he was surprised by Russell's passing because he had been in good health recently.
The TV star served in World War II before pursing an acting career. He's appeared on such shows as "The Adventures of Superman," "Alfred Hitchcock Presents" and "The Twilight Zone."
But his most famous role by far was the Professor, which he played over the show's 3 seasons.
"I've had people in the ensuing years say 'if they did 'Gilligan's Island' today you'd all be living in the same tent,'" Johnson said about how television has changed over the years. "It's true. That innocence was kept and it worked."
The actor's former co-star Dawn Wells, who played Mary Ann on the show, posted a picture on Facebook of herself, Johnson, and Bob Denver, who played Gilligan, with the caption:
"My 2 favorite people are now gone. The Professor [passed] away this morning. My heart is broken."
Denver passed away from cancer in 2005. Wells and the actress who played Ginger, Tina Louise, are now the only surviving original cast members.
A few hours before the announcement of Johnson's death, TV Land announced that they would be airing a "12-Hour-Tour" marathon of the hit series, 10 years after the show took a hiatus from the network.
Johnson is survived by his wife and daughter Kim.
