Bob Denver, 1935-2005
From his Associated Press obituary:
Denver's signature role was Gilligan. But he was already known to TV audiences for another iconic character, that of Maynard G. Krebs, the bearded beatnik friend of Dwayne Hickman's Dobie in the The Many Loves of Dobie Gillis, which aired from 1959 to 1963.
Gilligan's Island lasted on CBS from 1964 to 1967, and it was revived in later seasons with three high-rated TV movies. It was a Robinson Crusoe story about seven disparate travellers who are marooned on a deserted Pacific Island after their small boat was wrecked in a storm.
TV critics hooted at Gilligan's Island as gag-ridden corn. Audiences adored its far-out comedy. Writer-creator Sherwood Schwartz insisted that the show had social meaning along with the laughs: "I knew that by assembling seven different people and forcing them to live together, the show would have great philosophical implications."
