Kentucky-born Louis Mason enjoyed a long stage and screen career playing a vast array of rustic characters. In films from 1933, Mason could often as not be found portraying feuding hillbillies, backwood preachers, moonshiners and other assorted rubes. When he was given a character name, it was usually along the lines of Elmo and Lem. An off-and-on member of John Fords stock company, Mason showed up in Ford's Judge Priest (1934), Steamboat Round the Bend (1935) and Young Mr. Lincoln (1939), among others. Louis Mason remained active at least until 1953.
