HARLEMAN

HARLEMAN 05.12. 1922 Palmerton PA/USA 28.09. 2005 Nantucket MA/USA Donald Robert Fergusson Harleman obtained his MS degree from MIT in 1947, and the degree DSc. there in 1950, when he was a research assistant at the MIT Hydrodynamics Laboratory. From 1950 to 1956 he was assistant professor, then until 1962 an associate professor, and from then until retirement in 1991 professor of civil engineering first, later Ford Professor of Engineering. In parallel Harleman was from 1972 to 1983 head of the Water Resources & Environmental Engineering Division. He was from 1968 to 1969 senior visitor at Cambridge UK, and in 1977 visiting scientist of the International Institute of Applied Systems Analysis, Vienna, Austria. He was a member of the Water Pollution Control Federation WPCF, and of the International Association of Hydraulic Research IAHR. He was named in 1979 an outstanding alumnus of the Engineering College, Pennsylvania State University. He was awarded the 1960 ASCE Research Prize, the 1971 ASCE Karl Hilgard Hydraulic Prize, the 1973 ASCE J.C. Stevens Award, and ASCE’s 1983 W.W. Horner Award. Harleman was elected to ASCE Honorary Member in 1989. The D.R.F. Harleman Lecture was established in 2001. Harleman was a recognized international engineer, scientist and educator, whose research and innovations were directed toward improving water quality and making wastewater treatment available and affordable to all. He brought his expertise and enthusiasm to the next generation through leadership at the Institute. His is further known by the book Fluid dynamics, co-authored by James W. Daily (1913-1991). It may be compared with works of the calibre of Boundary layer theory by Hermann Schlichting (1907-1982). Anonymous (1966). D.R.F. Harleman. Civil Engineering 36(6): 52. P Anonymous (1982).

HARPER J.L. 21.09. 1873 Harpersfield NY/USA 28.11. 1924 Niagara Falls NY/USA John Lyell Harper graduated in 1897 from Cornell University, Ithaca NY, as mechanical engineer. In 1898 he became operating and construction engineer of the Twin City Rapid Transit Company, where he learned experimentation with electric and hydraulic machinery. From 1899 he was in charge of a project on the hydro-electric power plant of the St. Croix Power Company, Appleriver WI. In 1902 he moved to Buffalo NY, accepting a position with the Niagara Falls Hydraulic Power & Manufacturing Company as assistant to chief engineer Wallace C. Johnson (1859-1906). It was there where his principal work started, and the story of his life was intimately associated with the history of development of water power until his death. This Company started in 1881 with the construction of power house Station 1. In 1902, when Harper joined the Company, it had a capacity of 2,000 HP, and power house Station 2 had partly been constructed, with a capacity of 20,000 HP, to be completed in 1904, so that Station 1 was abandoned but the construction of Station 3 was initiated for a capacity of 130,000 HP. However, in 1909, the Governments of Canada and the USA set a limit to the water discharge to be diverted to hydro-electric power production. In World War 1, the Company and the Cliff Electrical Distribution Company were merged under the name The Niagara Falls Power Company, owning all developments on the American side and controlling the Canadian Niagara Power Company on the other side. The combined plants had a total capacity of 350,000 HP, which was a fitting tribute to Harper’s vision and ability, who was appointed vice-president in 1919 in addition to chief engineer. Harper was thereby especially interested to preserve the scenic beauty of the Falls. He built a model of the Niagara Falls and Rapids on a scale large enough to determine the effect of diversion and published the results of these studies. He was a man of high ideals and integrity, a loyal friend and was devoted to his family. Anonymous (1925). John L. Harper. Cornell Alumni News 27(14): 174. P Anonymous (1926). John L. Harper. Trans.
