Russell Johnson, the actor who played Professor Roy Hinkley on "Gilligan’s Island," has died of natural causes, The Wrap reports. He was 89.
Johnson, whose genius professor character was always one coconut away from inventing a way off the island, got his Hollywood start in '50s science fiction classics "This Island Earth" and "It Came From Outer Space." He also scored two appearances on "The Twilight Zone" and once acted opposite Ronald Reagan in the 1953 western film "Law and Order."
Prior to acting, Johnson served in the Army Air Corps during World War II. He earned a Purple Heart when his plane was shot down over the Philippines in 1945.
Johnson was married three times, most recently to actress Constance Dane.
Following news of his death, former co-star Dawn Wells, who played MaryAnn on "Gilligan's Island," took to Facebook to express her sadness.
