http://nj.essortment.com/maryelizamahon_rzuc.htm. Mary Eliza Mahoney was the first black professional nurse in America, and an active organizer among African American nurses. She was born in Boston, on May 7, 1845, the oldest of three children.
In 1878, when she was thirty-three years old, Mahoney began nurses' training at the New England Hospital. The nursing program was established by Dr. Marie Zakrzewska, one of the first women doctors in the United States. The courses were very difficult and the schedule was strenuous.
