While still a student he began a series of experiments, chemical and mechanical, the main object of which was the utilization of waste products, especially the transformation of animal substances, like hide, horn, tortoise-shell, and leather. He developed processes for the treatment of waste leather which fitted it for the lining of petroleum-barrels and fire-proof safes, and for use, under the name of "tanite," as a substitute for jet and ebonite in the manufacture of jewelry and fancy articles, and as a. base for solid emery-wheels. He has taken a leading part in the development and extension of grinding processes, and has been president of the Tanite company at Stroudsburg, Pennsylvania, which manufactures emery-wheels, since its organization in 1867.
