WASHINGTON – Lawrence Guyot, a civil rights leader who survived jailhouse beatings in the Deep South in the 1960s and went on to encourage generations to get involved, has died. He was 73.

Guyot had a history of heart problems and suffered from diabetes, and died at home in Mount Rainier, Md., his daughter Julie Guyot-Diangone said late Saturday. She said he died sometime Thursday night; other media reported he passed away Friday.

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.
