Russell Johnson was an American actor and writer best known for playing the part of Professor Roy Hinkley on the iconic television series "Gilligan's Island" and its sequels. In fact, he became so famous for the role that the character followed him long after the series ended and rendered him typecast for years afterward.

His Hollywood acting career began in 1952, with the college fraternity hazing exposé film "For Men Only" and in "Loan Shark," also released in 1952 and starring George Raft.

After the death of Bob Denver, he was one of the three original surviving cast members of "Gilligan's Island," the other two being Tina Louise, who played the part of Ginger Grant, and Dawn Wells, who played Mary Ann. His acting roles were reduced to reprising the role of the Professor in two "Gilligan's Island" reuinion movies and Professor-like roles on "Alf," "Newhart" and "Roseanne."
