About Mary Hinkson
Mary De Haven Hinkson was an African American dancer and choreographer known for breaking racial boundaries throughout her dance career in both modern and ballet techniques. She is best known for her work as a member of the Martha Graham Dance Company. Thankfully, the university was one of the first to have a real dance major which Hinkson abandoned all of her previous credits to join. During her first performance with them in Orpheus and Eurydice, a local afro-american paper cited her and Matt Turney, who became lifelong friends, as being the first African American members.
