STEWART J.T. 13.01. 1868 Loda IL/USA 09.06. 1928 St. Paul MN/USA John Truesdale Stewart obtained the BS degree from University of Illinois, Urbana IL, in 1893, and the civil engineering degree in 1909. He was from 1893 to 1897 engaged in general engineering practice in his State, and then was occupied with both drainage and railroad work. In 1899 he was appointed field assistant of the US Geological Survey USGS, and from 1904 he became drainage engineer within the US Department of Agriculture USDA, on drainage and irrigation work in South Dakota, North Dakota, Minnesota and Florida. Stewart was professor and chief of the Division of Agricultural Engineering at the University of Minnesota, Minneapolis MN, from 1908. During this era he conducted research on the drainage and development of peat lands, the durability of drain tiles, and the efficiency and maintenance of open ditches. Following his strong sense of loyalty and patriotism, he was active in the US Army, serving as lieutenant-colonel of Engineers in 1918. In 1922 he resumed his consulting practice as recognized authority on drainage and wetland development. He was member of the American Society of Civil Engineers ASCE, the Society of American Military Engineers, the Western Society of Engineers, and the American Society of Agricultural Engineers ASAE. Stewart prepared a number of technical papers and reports, several of which were published by the USDA. He was an authority in all matters relating to land drainage, the drainage of farms, including drainage legislation. He also developed an experimental drainage system at the University of Minnesota. He was in addition the senior author of the book Engineering on the farm, whose main chapters are 1. Introductory, 2. Materials of construction, 3. Building equipment, and 4. Mechanical equipment. He was described as an always courteous, friendly and interested person, who had many friends in and out of the engineering fraternity. He was fond of outdoor life, enjoying hunting and fishing.

STICKNEY 24.01. 1869 St. Paul MN/USA 27.01. 1929 Albany NY/USA George Fetter Stickney graduated in 1891 with the Ph.B. degree from the Sheffield Scientific School of Yale University, New Haven CT. He was an US assistant engineer on improvements of the rivers in Kentucky and of harbours in Northern New Jersey from 1893. He designed in 1901 a movable dam in Saint Mary’s River, Ontario, and in 1903 piers for a bridge at Selma AL, and the East Viaduct approach to the Mississippi Bridge, Thebes IL. Later, from 1905 to 1914, employed by the Department of the State Engineer and Surveyor of New York, he then designed and supervised the construction of a large part of the New York Barge Canal, and from 1915 to 1917 he made preliminary investigations for the proposed Lake Erie & Ohio River Canal. Stickney also served as captain during the Spanish-American War. He was a member of the American Society of Civil Engineers ASCE since 1906. As a consulting engineer, Stickney maintained an office at Albany NY from 1917 to 1928, thereby being in charge of hydraulic investigations for waterpower developments and river improvements. He was the inventor of the siphon spillway for discharging water through dams, and of an automatic movable crest for dams. These elements are described in the 1922 paper. The various types of siphons are detailed including their principles of operation. The major siphon spillways of the USA are described and their use is illustrated. Other articles deal with projects in which he was active during this period. Stickney was described as a person of keen intellect, who had the faculty of quickly sifting out the essential elements of a problem, and the ability to work out in detail an accurate solution. He was methodical and kept his records in precise and complete form. He was self-reliant, and on occasion was tenacious in holding to his views. Always he was a thorough gentleman, with an ever-present quiet dignity. He passed away due to stomach cancer. Anonymous (1922). Stickney, George F. Who’s who in engineering 1: 1209. Lewis: New York.
