Henry Arthur Callis

Henry Arthur Callis became a practicing physician, Howard University Professor of Medicine and a prolific contributor to medical journals. Often regarded as the "philosopher of the founders," and a moving force in the Fraternity's development, he was the only one of the "Cornell Seven" to become a General President. Prior to moving to Washington, D.C., he was a medical consultant to the Veterans Hospital in Tuskegee, Alabama. Upon his death in 1974, at age 87, the Fraternity entered a time without any living Jewels. His papers were donated to Howard's Moorland-Spingarn Research Center.
