In 1875 she appealed to the Women’s Education Association of Boston for help in establishing a laboratory at MIT for the instruction of women in chemistry. The Women’s Laboratory opened in 1876 with Professor John M. Ordway in charge, assisted by Richards. She held the position of instructor in chemistry and mineralogy in the Women’s Laboratory until it closed in 1883. From 1884 to her death in 1911, Richards was instructor in sanitary chemistry at MIT.
