Charles Osgood (?-?) appears to have become active in the Christian Science movement in the late 1870s. Little is known about him, but records suggest he studied with a student of Mary Baker Eddy's and maintained a healing practice in Boston, Massachusetts. By the early 1880s, Osgood appears to have been actively teaching and healing in Chicago, Illinois. One of his students, Emily S. Coursen, expressed her dissatisfaction with his teaching and went on to study with Eddy.
