The eldest of seven children of a Brooklyn bank executive, Robert F. Logan was eight years old when his family moved to Los Angeles. During his high-school years, Logan aspired to a career in professional sports, but was habitually sidelined by injuries and poor grades. Eventually, however, he was awarded a baseball scholarship to the University of Arizona. His ball-playing career came to an abrupt end when he was spotted by a Warner Bros. talent agent. After his movie debut in Claudelle Inglish, Logan was cast as slang-slinging parking lot attendant J. R. Hale in the weekly TVer 77 Sunset Strip (he replaced "Kookie"--aka Edward Byrnes--who'd been promoted to private eye), remaining with the series until 1963. He went on to co-star as Jericho Jones during the 1965-66 season of TV's Daniel Boone. For several years thereafter, little was heard from Robert Logan; he reemerged in the 1970s as star of the Wilderness Family movie series, and as producer and writer of similar family-oriented films.
