When The Bob Newhart Show premiered on CBS in 1972, it quickly became one of the most innovative and most beloved sitcoms of the decade. The series followed psychologist Dr. Robert Hartley, played by Bob Newhart, as he balanced his work life and patients, friends, and life at home with his wife Emily (Suzanne Pleshette). With its sharp writing and hilarious cast, the show ran for six seasons and remains one of the most defining sitcoms of the ’70s. Since Newhart passed away last year, it begs the question …who from the original main cast is still with us? As it turns out, there is one star left.
