Tom Hayden was elected SDS president for the 1962–1963 academic year, but his wife Sandra Cason "Casey" Hayden left Ann Arbor, and left him, heeding the call to return to the Student Nonviolent Coordinating Committee (SNCC) in Atlanta. She later recalled that in contrast to the interminable debates she had witnessed in Ann Arbor, in SNCC discussions the focus was on action and women had a voice. The Haydens divorced in 1965. That year, with other SNCC women, Casey Hayden coauthored "Sex and Caste" since regarded as a founding document of second-wave feminism.
