HALL W.M. 01.03. 1860 Fayetteville TN/USA 25.11. 1951 Parkersburg WV/USA William McLaurine Hall graduated in 1881 from the US Military Academy, West Point NY. For a period he was then engineer and chief engineer of the New Croton Aqueduct for the water supply of New York City, and later he did construction work for railroad companies in New York, Pennsylvania and Virginia States. In 1893, he joined the US Engineers remaining there in federal employment until his retirement in 1932. On the Rough River in Kentucky, he built what was believed to be the first monolithic concrete river lock in the world. Among the notable innovations introduced by Hall during the construction of Lock and Dam No. 18 on the Ohio River were the use of a core drilling to locate the bed rock, the anchoring of concrete masonry to the bed rock, the design of a novel bear-trap weir for controlling the pool stage above the dam, and the effecting of a new type of lock power plant. These methods were a standard practice after World War II in the USA. Hall also had full field charge of building sixteen Ohio River locks and dams. By an act of Congress he was retained in service beyond retirement age and served as chairman of a commission whose report was enacted into a law under which various government appropriations were made for flood control. While he was a member of the Parkersburg Water Works Commission WV in 1907, the controversial experimental river bed sand infiltration system was built, on which he wrote the 1917 paper. For notable service in the engineering field, Hall received in 1947 the honorary degree of Doctor of Science from Marietta College, Marietta OH. He was member of the American Society of Civil Engineers ASCE from 1893, becoming Life member in 1928. Anonymous (1952). William M. Hall. Trans. ASCE 117: 1301-1302. Hall, W.M. (1902).

HALMOS 06.12. 1877 Kassa/H 01.02. 1959 Manhasset NY/USA Eugene (Jenö) Erwin Halmos graduated in 1899 as a civil engineer from the Royal Joseph Technical University, Budapest H. He moved in 1910 to the USA, starting as an engineering draftsman in New York NY. He was from 1912 to 1947 design engineer and associate of the New York engineering firm Parsons, Klapp, Brinkerhoff and Douglas and successors, thereby in charge as chief engineer of the Parklap Construction Corp., New York NY, from 1920 to 1932. He further was engaged on designs of the Sherman Island, Spier Falls, Salmon River and Feeder Dam hydro-electric plants, all in New York State, and of the Sutherland Power and Irrigation Project in Nebraska. Further projects during the 1920s and 1930s included twin graving docks of the Norfolk Navy Yard, or Bayboro Harbour at St. Petersburg FL. He was also in charge of the Cape Cod Canal hydraulic design, the Bayonne Ship Terminal, harbour developments at Ciudad Bolivar and Los Morcos in Venezuela. During World War II he acted as chief engineer of the naval dry docks at Portsmouth RI, Boston MA, and Brooklyn NY. After 1947 Halmos directed the preparation of a Rapid Transit Report for Sao Paulo BZ, he studied the transit situation of Zurich CH, he prepared a Port Program for Turkey, but was chiefly engaged on the design of the Seyhan, Hirfanli, Kemer, and Demirkopru hydro-electric plants in Turkey. He authored numerous papers and reports mainly in the Engineering News-Record, and the ASCE journals. He became widely known in the hydraulic community also by his translation of the book on water hammer by the Italian Lorenzo Allievi (1856-1940), who led the mathematical bases for the fundamental wave phenomena exerted in unsteady pipe flow. He thereby was a participant of the 1933 Symposium on Water Hammer, organized by the ASME Hydraulic Division, and the ASCE Power Division in New York. Abbett, W.A., Halmos, E.E. (1957).
