HATHAWAY 11.10. 1895 Menomonie WI/USA 01.10. 1979 Washington DC/USA Gail Abner Hathaway received a BS degree in civil engineering from Oregon State College in 1922, and the honorary D.Eng. degree from Drexel Institute of Technology, Philadelphia PA, in 1951. He started his career as a construction engineer in 1919, joining in 1928 the US Corps of Engineers until retirement in 1957. He was engaged with field assignments until 1937, was then chief of reservoir regulation and the hydrology section at the Office Chief of Engineers, Washington DC, until 1945, from when he was the special assistant to the chief of engineers, Dept. of Army, on flood control, river and harbour project planning and construction programs. After retirement, he was an engineering consultant for the World Bank. Hathaway was recognized internationally for his work in hydrological engineering, and problems relating to the planning, design and operation of flood control, navigation and multi-purpose projects. He was particularly concerned with hydraulic matters on an international scale. He was in 1946 the engineering consultant to President Truman’s Cabinet Committee on Palestine during meetings in London, and in 1947 consultant to the Venezuelan government on flood control and water resources development. Later he was involved in large hydropower schemes on Indus River in Pakistan, and the High Aswan Dam in Egypt. He served in 1951 as ASCE president, and from 1952 to 1958 as president of the International Commission of Large Dams ICOLD. Anonymous (1957). Gail A. Hathaway. Power Engineering 61(1): 4.

HATTON 11.08. 1860 Avondale PA/USA 11.11. 1933 Milwaukee WI/USA Thomas Chalkley Hatton was educated in public schools. He began his career in 1878 with railway companies, and in 1882 was a hydrographer in the Department of Public Works, Canada. From 1883 he was employed as assistant city engineer, Wilmington DE, and from 1900 was engineer of the Street and Sewer Department, in charge of the extension of the sewerage system. He was also private consultant for similar works in the Southeast, engaged on the construction of filtration plants and distribution systems for Ashbury Park NJ, or Austin PA. In 1914 he went to Milwaukee WI, as chief engineer of the then recently created Sewerage Commission, serving until 1927. From then until his death he was engaged in private practice, and appointed in 1930 consulting engineer to the Milwaukee Sewerage Commission. His death was caused by a car accident. Hutton supervised as chief engineer of the Sewerage Commission the development of the activated sludge system in the USA. This work consisted of the design, construction, and operation of the intercepting sewerage system and the sewage treatment plant for the Metropolitan District of the County of Milwaukee. He was initiative and had the energy to advance the activated sludge practice of sewage disposal, which from 1915 was developed from its early experimental stages into a practical and efficient process, currently used extensively all over the world. He was in addition connected with the Great Lakes Water Diversion, involving the Sanitary District of Chicago IL. He further was engaged on the design of an activated sludge sewage treatment plant for East Chicago IL. He was president of the American Society of Municipal Engineers, member of the Institute of Consulting Engineers, the Institution of Civil Engineers ICE, London UK, and of the American Society of Civil Engineers ASCE. The Pennsylvania Military College, Chester PA, conferred upon him the Master Degree in civil engineering in recognition of his outstanding work in connection with the activated sludge process.
