The University of Kiel, in Denmark, conferred upon him the degree of Ph.D. A new genus of plant was named Schweinitzia in his honor, and while a resident of Salem he was elected president of the University of North Carolina, which honor he declined because it involved relinquishing work in the Moravian church.
