Sidney Alexander and his wife Fanny were natives of Sharkey County and rights activists. In addition to serving as an administrator for anti-poverty programs, Alexander was active in voter registration efforts and the Mississippi Freedom Democratic Party.
In 1967, Alexander was a co-plaintiff in the Willis v. Carson suit. Willis v. Carson challenged the state of Mississippi's systematic measures designed to prevent women and African-Americans from serving on juries.
