William Haydon Burns (March 17, 1912 – November 22, 1987) was the 35th Governor of Florida from 1965 to 1967. He was also Mayor of the city of Jacksonville, Florida from 1949 to 1965.
Born in Chicago, Illinois, Haydon Burns' family moved to Jacksonville in 1922, where he attended Andrew Jackson High School before going on to attend Babson College in Massachusetts. Before the outbreak of World War II he was an appliance salesman and a flight school operator. During the war, he joined the U.S. Navy and was posted as a technical officer in the office of the Secretary of the Navy. Following the war, he returned to Jacksonville and began a public relations and business consulting firm and worked selling appliances.
In 1949 Burns announced his intention to run for Mayor of Jacksonville against incumbent C. Frank Whitehead. He defeated Whitehead in the Democratic Party primary, and then faced Jacksonville businessman William Ashley, a Democrat running as a political independent, in the general election – an unusual occurrence, as Democrats had been dominant in city politics for decades. On June 21, 1949, Burns defeated Ashley to become the mayor of Jacksonville.
