Bob Denver, whose portrayal of goofy first mate Gilligan on the 1960s television show "Gilligan's Island," made him an iconic figure to generations of TV viewers, has died, his agent confirmed Tuesday. He was 70.

Denver died Friday at Wake Forest University Baptist Hospital in North Carolina of complications from treatment he was receiving for cancer, his agent, Mike Eisenstadt, told The Associated Press.

He'd also undergone quadruple bypass surgery this year.
