DELAPP 18.07. 1912 Kansas City KS/USA 03.06. 2002 Frazee MN/USA Warren William DeLapp obtained the BS degree in civil engineering from Kansas State University, Manhattan KS, in 1935. He then joined the United Fruit Co. as a hydraulic engineer and designed and constructed irrigation schemes in Guatemala. In the early 1940s he obtained the MS degree from State University of Iowa, Iowa City IA, and then accepted a teaching position at the University of Minnesota, Minneapolis MN, and there instructed mathematics and mechanics, ultimately receiving the PhD degree. He accepted in 1947 a position at the Department of Civil Engineering of Colorado State University, Fort Collins CO, from where he took a leave of absence from 1959 to 1961 to Peshawar, Pakistan, helping to develop a hydraulic laboratory at the university. He then returned to Colorado, where he worked until his retirement from the University in 1970. He then was engaged by a consulting engineer at Denver CO, and worked on complicated water drainage and water right problems for years. He permanently returned to Minnesota in 1986, where he enjoyed several years of lakeside retirement life. DeLapp made few but interesting publications during his stay in academia. The 1940 Report is his MS thesis, dealing with sediment transport in upward flow, as is typically observed with wave run-up in the coastal environment. The 1947 PhD thesis deals with a then novel problem of air entrainment in open channel flow. During the following decade, the University of Minnesota in general, and its St. Anthony Falls Hydraulic Laboratory in particular, were heavily involved in this task, culminating in benchmark papers of Lorenz G. Straub (1901-1963) and his colleagues. Anonymous (1960). De Lapp, Warren W. American men of science 10: 908. Cattell: Tempe AZ. DeLapp, J.R. (1995). Stories from my early years: Warren W.

DEMING 21.02. 1817 Berlin CT/USA 10.01. 1894 Salem OH/USA John Deming established in the 1830s with his elder brother William a general store at New Lyme OH. Before moving to Salem OH, John was involved in wholesale and retail businesses with his father-inlaw. Around 1856, he there opened a grocery store, thereby becoming interested in the great success of manufacturers of labor-saving tools for carriagemakers and blacksmiths. He saw how the market for the firm’s products continued to grow throughout the country. Deming Pumps including the old ‘Pitcher Spout Pump’, on display at the Salem Historical Society Museum, symbolizes the Deming Co. This is the type of pump that could be found in the kitchens of many old farm houses. Also called ‘Cistern Pump’, it was used most commonly in houses for pumping cistern or well water. Because the cylinder was in the stock of the pump, it was limited in its capacity to withdraw water from a depth of no more than 7 m. When Deming rode into Salem on horseback in 1862, carrying his only possessions in a money belt, it hardly was an auspicious beginning for what today is an internationally-known name in the pump business. He eventually joined the manufacturing business of Dole and Silver, which became the Dole, Silver & Deming Co., and later the Silver & Deming Mfg. Co. It began manufacturing hand and windmill pumps in 1880. In 1890 the firm divided into two separate entities, with Deming specializing in pumps and hydraulic machinery. Up to 1894, the line of pumps manufactured included house force pumps, well pumps, rotary pumps, hydraulic rams, and a small line of spray pumps. The firm grew rapidly, expanding to produce pumps in sizes and capacities from the smallest to the large triplex and deep-well power pumps for use in mines, factories and waterworks. Deming products were sold throughout the world. Its pumps earned the reputation of being the world’s best. One of the company’s most memorable pumps was built in 1905. It was one of the largest ever manufactured in the USA. The giant pump, shipped to southern California for irrigation purposes, had a capacity of five million gallons a day. In 2006, the Deming Co. closed its doors and left Salem. Anonymous (1894). John Deming. Iron Age 53: 166. Shaffer, D.E. (2002). Salem: A Quaker city history.
