Arthur Chopin Watson (December 15, 1909 – November 15, 1984) was an attorney, state legislator, civic leader, philanthropist, and chairman of the Democratic Party of Louisiana from 1968 to 1976. He was afflicted with polio in infancy and lost the use of both legs, and his mother died when he was only seven. However, his zest for living gave rise to his nickname "Speedy."
