Was one of only three co-stars of Petticoat Junction (1963) who remained with the series for its entire seven-year run, the others being Linda Henning and Frank Cady.
Edgar Buchanan's grandfather, Bramentus L. Buchanan (1840-1904), was a private in Company A, 6th Missouri Cavalry (Union) as well as the Dade County, MO Home Guard (Union) during the American Civil War (1861-1865).
Was originally a dentist with his own practice. At age 38, he turned the practice over to his wife and began his acting career.
His friend of many years, Glenn Ford, once told a story of when Edgar was preparing to do some painful dental work on him. The anesthesia consisted of others passing by and allowing the patient, Glenn, to take swallows of whiskey to help ease the pain of the process. About every third drink Glenn took, Edgar took one as well.
Father of Buck Buchanan.
