Died. W. Lee ("Pappy") O'Daniel, 79, Texas Governor (1939-41) and U.S. Senator (1941-49) whose raucous hillbilly campaigns amused a generation of Texans; in Dallas. A flour salesman and radio singer, O'Daniel entered politics in 1938 by running for Governor on a platform that included the Ten Commandments and mother love; he stumped the state singing his theme song, "Pass the Biscuits, Pappy" and won by a landslide. Though he was inept as Governor, Texans gave him a second term, then sent him to the Senate after a primary battle in which he defeated Congressman Lyndon B. Johnson.
