This series contains correspondence, memoranda, and reports pertaining to Paul Quattlebaum's nine year tenure in the South Carolina Senate. Paul Quattlebaum entered the Senate in the summer of 1935 to fill out the unexpired term of deceased Horry Senator H. Kemper Cooke. Quattlebaum successfully stood for re-election for a full four-year term in 1936 and was subsequently returned to the Senate in 1940. He worked untiringly to enhance the Horry County highway network and took an active interest in agricultural affairs, the Medical College of South Carolina, the Santee-Cooper hydroelectric project, and the State Historical Commission. Conway attorney Frank A. Thompson defeated Quattlebaum in his third bid for re-election in the summer of 1944.
