1951A bomb explodes at the home of Harry T. Moore and Harriette V. S. Moore, early leaders of the Civil Rights Movement, killing Harry instantly and fatally wounding Harriette.^[†]

Harry T. Moore and his wife, Harriette V. S. Moore, were pioneer activists and leaders of the early Civil Rights Movement in the United States and became the first martyrs of the movement. On the night of Christmas, December 25, 1951, a bomb that had been planted under the bedroom floor of the Moores' home in Mims, Florida, exploded. They had celebrated their 25th wedding anniversary earlier that day. Harry died in the ambulance in transit from the attack, and Harriette died from her injuries nine days later, on January 3, 1952. Their deaths were the first assassination of any activist to occur during the Civil Rights Movement and the only time that a husband and wife were killed during the history of the movement.
