Civil rights legend Bob Moses has died at age 86.

The trailblazer was born in New York City in January 1935 and grew up in Harlem. In the late 1950s, he began working on the civil rights movement.

Moses was the architect of the 1964 Voter Registration Campaign, the Mississippi Freedom Summer Project, among several other civil rights projects. His family confirmed that he died Sunday morning in Hollywood, Florida.

Mayor Bill de Blasio quote tweeted, "Bob Moses was a son of Harlem, a Bronx educator, and a lifelong activist. He knew the right to vote is sacred and spent his life fighting the racist systems that hold our democracy back."
