Aaron Manasses McMillan (November 3, 1895 – June 1, 1980) was a medical missionary to Angola and a civic leader and legislator in Nebraska.
He then was invited by the American Board of Commissioners for Foreign Missions and the Black Congregational Church to serve as a medical missionary in Galangue, Portuguese West Africa, where he worked from 1931 to 1948.
[5] McMillan was a last-minute addition to the 1928 primary ballot for the ninth district of the Nebraska House of Representatives, where he defeated dentist John Andrew Singleton.
[5] While Willena had no formal medical training, she also worked in hospital and in particular supervised an infant care clinic.
[5] The couple spoke Portuguese and learned the local language of Umbundu, and they were very well liked and respected by the communities they served.
[5] While in the United States, the couple met white doctor Willis F. Pierce of Clarinda, Iowa, who promised a large donation in support of the hospital.
[4] Further donations by the Women's Association of the Middle Atlantic Conference of the Congregational and Christian Churches allowed the construction of a surgery unit.
[4] Over the years, the hospital's expansions covered 4 acres (1.6 ha) containing 45 buildings, the two-story brick hospital, 130 beds, up-to-date equipment (including a new sterilizer), a chapel dedicated to Aaron's father, Reverend Henry R. McMillan, and training facilities for medical and business staff.
[5] People's Hospital closed after five years, and McMillan continued to work as a doctor in an office he had built for himself at that location.
