Harry Tyson Moore (November 18, 1905 – December 25, 1951) was an African-American educator, a pioneer leader of the Civil Rights Movement, and founder of the first branch of the National Association for the Advancement of Colored People (NAACP) in Brevard County, Florida.
Harry T. Moore and his wife, Harriette Vyda Simms Moore, also an educator, were the victims of a bombing of their home in Mims, Florida on Christmas night 1951. He died in an ambulance on the way to a hospital in Seminole County while she died January 3, 1952 at the hospital in Sanford, Florida. Forensic work in 2005-6 resulted in the naming of the probable perpetrators as four Ku Klux Klan members, all long dead by the time of the investigation. The Moores were the first NAACP members to be murdered for civil rights activism; Moore has been called the first martyr of the early stage of the Civil Rights Movement.
