Frank Randolph Cady (September 8, 1915 – June 8, 2012) was an American actor best known for his recurring and popular role as storekeeper Sam Drucker in three American television series during the 1960s – "Petticoat Junction", "Green Acres", and "The Beverly Hillbillies" – and his earlier role as "Doc Williams" on "The Adventures of Ozzie and Harriet".
Frank Cady made his name in American television during the middle years of his life. 
The wording of the statement was intentionally vague using the two phrases "Made his name" and "middle years of his life". These two phrases require social context to understand. He lived to nearly 95 and if the height of his fame came during the 1960s this would be the "middle years". It is vague but not incorrect.
