SANGSTER

SANGSTER 09.12. 1925 Austin MN/USA 22.08. 2000 Atlanta GA/USA William McCoy Sangster was educated at the State University of Iowa, Iowa City IA, from where he obtained the BS degree in 1947, the MS degree in 1948, and the PhD in 1964. He was there assistant instructor in 1948, and from assistant professor to civil engineering professor until 1967 at University of Missouri, Columbia MO. From 1964 to 1967 he was in parallel associate dean of its College of Engineering, and associate director of its Engineering Experiment Station. From then he was professor of civil engineering at Georgia Institute of Technology, Atlanta GA. Later, he was there the director and Dean of the School of Engineering. He was closely related to the American Society of Civil Engineers ASCE, taking over as one of the youngest presidents in 1974. He also was a member of the American Society of Engineering Education. He was awarded a graduate fellowship to the State University of Iowa in 1954, and a National Science Foundation Science Faculty Fellowship for study there in 1962. He also served as chairman of the ASCE National Water Resources Meeting at Atlanta GA in 1972. He received the Linton E. Grinter Distinguished Service Award from the Accreditation Board for Engineering and Technology in 1991. Sangster had research interests in the hydrodynamic stability of stratified flows, orbital mechanics, and general hydraulics. His PhD thesis was concerned with the head losses of junction manholes as used in sewer hydraulics. However, the manhole geometry considered did not account for the current standard, because no benches were included. He also provided the design basis for better storm drainage facilities under highways. During his presidency, he emphasized progress in ASCE’s policing of the ethics of its members and its efforts to streamline administrative procedures. Anonymous (1964). Sangster, W.M.

SAPH 26.10. 1871 San Jose CA/USA 13.02. 1920 Berkeley CA/USA Augustus Valentine Saph graduated in 1894 from the College of Civil Engineering, the University of California, receiving there the MS degree in 1896, and then acted as an instructor there in drawing and mathematics until 1900. He continued his studies at Cornell University, Ithaca NY, receiving the PhD degree in 1902. From 1903 to 1905 he was engaged as a structural engineer at Reno NV for the US Reclamation Service, and then on the TruckeeCarson Project, designing the diversion dams and other structures. In 1906 he was employed by a structural engineer to design bridges and buildings. From 1908 to 1911 he acted as assistant engineer in the office of the City Engineer of San Francisco CA, designing the College Hill Viaduct, pumping stations and the Ashbury Heights Tank. From then to 1914, Saph was the assistant state engineer of California acting as chief engineer for the Board of State Harbor Commissioners at San Francisco CA, in charge of design and water front construction and maintenance. He became also engineer of the Spring Valley Water Company of San Francisco, in charge of the design of the water tower for the Calaveras Dam. He finally opened in 1914 his office at San Francisco, specializing in structural engineering. Saph suddenly passed away during an influenza epidemic. Saph’s name is known for a notable discussion submitted in collaboration with Ernest William Schoder (1879-1968) on the famous paper by Gardner Stewart Williams (18661931), C.W. Hubbell, and George Harrison Fenkell (1873-1949). Therein, the Pitot tube was used for discharge measurement in pipe flow, and its rating in a circular tank is discussed. The large number of discussers compared the current meter measurements with other recording methods. In 1903, the two discussers presented their own paper on pipe flow resistance based on a large experimental campaign. They first investigated the transition between laminar and turbulent flows, and then proposed an equation for the average velocity in terms of the hydraulic gradient and the hydraulic radius for a variety of pipe boundary material.
