Glen A. Larson, the television writer-producer behind TV hits Quincy M.E., Magnum, P.I., Battlestar Galactica, and Knight Rider, has died at age 77.
A singer in the 1950s straightedge pop group The Four Preps, Larson went on to produce a series of sci-fi influenced dramas following the early success of his The Six Million Dollar Man. His influence was most recently seen after his 1970s Battlestar Galactica, which starred Lorne Greene and Richard Hatch as leaders of a homeless fleet wandering through space, was re-imagined and rebooted as a series in 2004. That particular iteration of Galactica made TIME’s 100 top television shows of all-time.
Larson died of esophageal cancer, his son James told the Hollywood Reporter.
