Jason Robards, Sr.
Jason Nelson Robards, Sr. was an American stage and screen actor, and the father of Oscarwinning actor Jason Robards, Jr. Robards appeared in many films, initially as a leading man, then in character roles and occasional bits.
Robards was born Jason Nelson Robards on a farm in Hillsdale, Michigan, the son of Elizabeth , a schoolteacher, and Frank P. Robards, Sr., a farmer and post office inspector who managed Theodore Roosevelts 1912 Presidential campaign in Michigan. He was raised in Chicago, Illinois. He trained at the American Academy of Dramatic Arts. He was consistently billed as Jason Robards, as his more famous son, also named Jason Robards, did not come into prominence until the end of the elder Robards career. He is only referred to as Jason Robards, Sr. in retrospect. He died in 1963, having lived to see his namesake son and grandson carry on the family acting tradition.
