Russell Johnson, who played Professor Roy Hinkley on Gilligan's Island
, has passed away at age 89.
The actor died of kidney failure Thursday at his home in Washington, surrounded by his wife Constance Dane and daughter Kim Johnson.
"He died at home, peaceful, in his sleep at 5:21 a.m. today," Dane told ABC News
. "[He was] a very brave guy who knew what he wanted, and he wanted to be at home."
His death came quickly, says his agent Michael Eisentstadt.
"I spoke to him right before the holidays and he did an autograph job," says Eisentstadt. "He had just done that and he was fine."
Dawn Wells, who played Mary Ann on the show, posted a picture of herself, Johnson and Bob Denver, who played Gillian and died in 2005, to Facebook
to express her grief.
"My 2 favorite people are now gone. The Professor [passed] away this morning. My heart is broken."
