Hennesey (1959)

Jackie Cooper played Hennesey, a Navy doctor in an onshore office. Abby Dalton, very young and beautiful then, played his blonde yeoman/secretary/nurse. She had a crush on Hennesey but he maintained his professional dignity. Much of the series was about his gradually warming up to her interest. Neither a drama nor a comedy, it was mostly a character study. The third regular character was a beefy Navy seaman who aspired to become an astronaut until Hennesey found he had an inner-ear defect & was ineligible.
