MILLIKAN

MILLIKAN 23.08. 1903 Chicago IL/USA 02.01. 1966 Pasadena CA/USA Clark Blanchard Millikan graduated in 1924 from Yale College, earning in 1928 his PhD in physics at Caltech under Harry Bateman (1882-1946). He then joined the faculty, becoming in 1940 full professor, succeeding Theodor von Karman (1881-1963) in 1948 as director of the Guggenheim Aeronautical Laboratory at Caltech. Among the first Fellows of the Institute of Aeronautical Sciences IAS, he served as president in 1937, and delivered the third Wright Brothers Lecture at Columbia University, New York NY in 1939. He presented the 1957 Wilbur Wright Lecture at the Royal Aeronautical Society, London. During his early career at CalTech, Pasadena CA, Millikan became one of the most outstanding experts in wind-tunnel experimentation. He directed design, construction, and operation of the CalTech Cooperative Wind Tunnel, supervising many scientific experiments that helped bring about greatly improved performance and efficiency of military and commercial aircraft. This activity earned him the Presidential Medal and the King’s Medal of Great Britain. During Word War II and the following years, Millikan’s interest turned to guided missiles and rockets. Both his theoretical and experimental work led to improvements in reaction propulsion and in the flight at supersonic speeds. Around 1950 he was chairman of the Guided Missiles Committee. He also served as chairman of the Space Systems Division Advisory Group of the Air Force Scientific Advisory Board, and was a member of the Army Ballistic Research Laboratory’s Scientific Advisory Committee.

MILLS 01.11. 1836 Bangor ME/USA 04.10. 1921 Hingham MA/USA Hiram Francis Mills graduated as a civil engineer from the Rensselaer Polytechnic Institute, Troy NY. During the next twelve years he was engaged with tunnel construction and dam erection on Deerfield River and Penobscot River. He conducted studies relating to water-power developments. In 1868 he opened his own office at Boston MA, soon attaining a high place in his profession. Although his principal work was done in Massachusetts, he was also a consultant in the USA and Mexico. He for instance was chief engineer of Essex Company, Lawrence, and of the Locks and Canals Company, Lowell MA. At Lowell, Mills undertook a series of experiments on the water flow in natural and artificial channels, which led to the perfection of the piezometer and also advanced the knowledge on turbines. Due to lack of time, he had to abandon these activities, however, and his conclusions were only systematized posthumously in the 1923 book. As consultant to the Boston Metropolitan Water and Sewerage Board, he was responsible for the design of water supply, drainage, and sewer systems. When the Massachusetts State Board of Health was organized in 1886, he accepted the committee chair, a position which he held almost to his death. Much of the success of the Board was due to his efforts, because he not only standardized methods of sampling and analysis but also initiated tests on the purification of water and sewage. From these activities emerged the great Lawrence Experiment Station, which has long been recognized as the foremost in America. Mills also designed the slow-sand filter which marked the beginning of an new era in municipal engineering. He was a successful man of business, director and president, and accumulated a fortune which he used to found educational institutions. Anonymous (1921). Hiram F. Mills dead.
