The appointment of Charles Ezra Greene, Harvard, '62, Mass. Inst. Technology, '68, in 1872 marks a definite period in the history of this department. He found himself associated with two other men who had been instructors for a short period under Professor Wood, J.B. Davis, '68_e_, Assistant Professor of Civil Engineering, who became Professor of Geodesy and Surveying in 1891, and Charles S. Denison, Vermont, '70, who was to be in later years Professor of Stereotomy, Mechanism, and Drawing. These men saw the Department grow almost to its present proportions, and, as the first Faculty, formed a most harmonious combination of unusually varied elements. Professor Greene was a scholar and scientist who had a wide reputation as an engineer and an author; Professor Davis, on the contrary, was a practical man, a genius, whose love of the outdoors and fatherly care of his "boys" even extended to their "rubbers" on wet days, while his homely and wise sayings endeared him to every student. Professor Denison was a bachelor, small and very particular in personal appearance, who was long known by the students as "Little Lord Chesterfield," but an able teacher who was loved for his big heart and his very mannerisms. A course in mechanical engineering was again inaugurated in 1881 when Mortimer E. Cooley, Annapolis, '78, Assistant Engineer, U.S.N., was detailed to the University by the Navy Department and became the first Professor of Mechanical Engineering. In 1885 he resigned from the Navy and definitely cast his lot with the University, becoming Dean of the College of Engineering in February, 1904, after the death of Professor Greene in October, 1903. At the same time Professor Davis became Associate Dean and maintained an intimate and paternal care over the students until his retirement in 1910. The Department of Electrical Engineering was organized in 1889, under the charge of Henry S. Carhart, Wesleyan, '69, Professor of Physics, and one instructor, George W. Patterson, Yale, '84, who became the first Professor of Electrical Engineering in May, 1905. In 1899 a course in Naval Architecture and Marine Engineering was created with Herbert C. Sadler, Glasgow, '93, as the first Professor. The following year the first degree was conferred in a new Department of Chemical Engineering, and in 1902 Edward DeMille Campbell, '86, became head of the new division as Professor of Chemical Engineering and Analytical Chemistry.
