April 1, 1946 (Monday) A tsunami, generated by an 8.6 magnitude earthquake near Alaska, killed 159 people in Hawaii. Waves high struck Hilo shortly after local time, and almost five hours after the Alaskan tremor. Bituminous coal miners walked off the job across the United States, as 400,000 UMWA members went on strike in 26 states. The miners returned to work after six weeks.

The United States Supreme Court declined to grant certiorari on an appeal from the 5th Circuit Court of Appeals in Chapman v. King, et al. 154 F.2d 460 (5th Cir. 1946), which held that African-Americans could not be barred from voting in primary elections in Georgia. At the time, the Democratic Party was the dominant political party in Georgia and other Southern states in the Fifth Circuit, and the winner of the Democratic primary was frequently unopposed in the general election. Primus E. King of Columbus, Georgia, had commenced the suit in 1944, to challenge the practice of allowing political parties to set their own rules concerning who would be allowed to vote in a nominating election. The decision paved the way for allowing Black Americans to vote in primary elections in other states.
