Personal Sketches of Marine Men Herbert C. Sadler, Dr. Sc., Professor of Naval Architecture, University of Michigan By A. H. Jansson N JUNE, 10, Prof. Herbert C. Sadler, head of the department of naval architecture and marine engineering at the University of Michigan, will sail, with Mrs. Sadler from Montreal, for Glas- gow where the degree of doctor of laws will be conferred upon him by the University of Glasgow. This honor coming from the first university to establish a civilian school of naval architecture and marine engi- neering is a significant recognition of the wide scope and high quality of the work done by Doctor Sadler. When the University of Michigan in the fall of 1900 decided to establish a regular course in naval architec- ture and marine engineering, Herbert C. Sadler, then 28 years of age, was chosen to take charge, a position he holds today with the added responsibility of being acting head of the course in aeronautical engineering. He was so youthful in appearance when he arrived at Ann Arbor, so the story goes, that a group of sophomores in one of their raids mistook him for a freshman. His appearance however belied his experience. Born in London, Aug. 27, 1872, he was educated at Dulwich college, London, and at the University of Glas- gow where he received the degree of bachelor of science in 1893 and the degree of doctor of science in 1902, two years after his appointment at Michigan. Right here it may be well to emphasize the fact that Professor Sadler is not merely a bookish academic student of his profession. His practical experience began 37 years ago in the summer of 1890, the year he entered the University of Glasgow when he enrolled as an appren- tice in the firm of A. & J. Inglis, engineers and ship- builders. Until his graduation he spent the winters and summers alternately in practical work as a shipwright S DIRECTOR of the school of nav- al architecture and marine engi- neering at the University of Michigan since its inception 27 years ago, he has made an important contribution to bet- ter ship design. IS close contact with conditions in actual service through consulting work has given direct practical appli- cation to much of the work in testing models and to the theoretical studies carried out at the university. EK BELIEVES that the naval architect should go beyond the at- tempt to obtain mechanical efficiency and that he should study the economics of the entire operation with the view of making that operation profitable. and in all branches of steel, ship structural fabrication and erection and at his studies at the university. After graduation he completed his apprenticeship in the drafting room and was employed in that capacity until 1896. He was then appointed as assistant to Sir John Harvard Biles, then professor of naval architec- ture at the university, and was lecturer in marine engi- neering. He was also associated with Professor Biles in his private work as consultant to many steamship lines, Shortly after he went to Michigan, it was decided to build a model testing tank, and the design of this tank and the accompanying equipment was placed in Professor Sadler’s charge. Hig research work has been largely in connection with questions relating to the resistance of ships, the results of which have been published in many papers read before various technical societies devoted to naval architecture and marine engineering, and appear also in most of the leading textbooks dealing with this subject. He has also contributed many other papers relating to the design and construction of ships, both to technical societies and the technical press. Since his appointment as professor of naval architec- ture at the University of Michigan, he has also engaged in a general consulting practice, both in the United States and in Canada. He has acted as appraiser of vessel property for the state of Michigan, and consultant to many of the steamship lines, among which may be men- tioned the Detroit and Cleveland Navigation Co.; the Huron Transportation Co.; the White Star line; the Hudson River line; the Canada Steamship lines; the Northern Navigation Co.; the Bradley Transportation Co., and the Goodrich Transit line.
