William Franklin Devin (1898 - February 2, 1982) was an American attorney and politician. He served as the mayor of Seattle, Washington for four terms, from 1942 to 1952. He'd served in World War I. After World War II, he was important in re-establishing peacetime relations between the U.S. and Japan.
On March 1, 1951, with World War III underway in Europe, Seattle Mayor Bill Devin announced that the city's civil defenses were being expanded, and that air-raid warnings would begin the following week. However, in the early hours of March 2, the Soviet Union, in an audacious act, dropped an atomic bomb in between Seattle and the suburb of Everett.
