Everett Verner Stonequist (October 5, 1901 – March 26, 1979) was an American Sociologist perhaps best known for his 1937 book, The Marginal Man "The marginal person is poised in the psychological uncertainty between two (or more) social worlds; reflecting in his soul the discords and harmonies, repulsions and attractions of these worlds...within which membership is implicitly if not explicitly based upon birth or ancestry...and where exclusion removes the individual from a system of group relations."
Stonequist spent most of his academic life teaching at Skidmore College, Saratoga Springs, NY, where he was a well-known figure as a leader on the city's planning commission and housing authority.
His book, The Marginal Man, called attention to the problems experienced by people making transitions between different cultures, and specifically to pressures felt by minority and ethnic group members in American society.
This work was continued and developed further by Howard S. Becker and others most notably J M Billson, L H Bowker, F M Cox, A F Buono, J B Kamm, J Golden, Mark A Grey, and R A Stebbins.
"One of Park's students [at Chicago], Everett Stonequist, was writing The Marginal Man--A Study in Personality and Culture Conflict (1937).
