A Mississippi native, Guyot (pronounced GHEE-ott) worked for the Student Nonviolent Coordinating Committee and served as director of the 1964 Freedom Summer Project, which brought thousands of young people to the state to register blacks to vote despite a history of violence and intimidation by authorities. He also chaired the Mississippi Freedom Democratic Party, which sought to have blacks included among the state's delegates to the 1964 Democratic National Convention. The bid was rejected, but another civil rights activist, Fannie Lou Hamer, addressed the convention during a nationally televised appearance. Guyot was severely beaten several times, including at the notorious Mississippi State Penitentiary known as Parchman Farm. He continued to speak on voting rights until his death, including encouraging people to cast ballots for President Barack Obama. Guyot was born in Pass Christian, Miss., on July 17, 1939. He became active in civil rights while attending Tougaloo College in Mississippi, and graduated in 1963. Guyot received a law degree in 1971 from Rutgers University, and then moved to Washington, where he worked to elect fellow Mississippian and civil rights activist Marion Barry as mayor in 1978.
