he worked on pearlitic iron for surface hardening and with Upthegrove on the fracture tests for melt quality. In 1951 Professor Richard A. Flinn (City College of New York '36e [Ch.E.], Sc.D. Massachusetts Institute of Technology '41) replaced Rote. Flinn had an active interest in isothermal transformations of alloy iron and mechanisms of graphitization of gray and nodular irons.
Other research. — Associate Professor Lloyd Earl Brownell (Clarkson '37, Ph.D. Michigan '48) joined the staff in 1942. He has studied flow of fluids through porous media, has had an active interest in food technology and the effect of radiation on food and drug sterilization, and has contributed to the design of chemical engineering equipment. Sliepcevich has done valuable work on light scattering functions for the determination of particle sizes in fogs and sprays. Assistant Professor Edwin Harold Young (University of Detroit '42, M.S.E. Michigan '49), who came in 1947, has worked with Brownell on equipment design. Assistant Professor Lloyd Lute Kempe (Minnesota '32, Ph.D. ibid. '48) joined the staff on a half-time basis in 1952 while serving half-time with the Bacteriology Department of the Medical School. He is interested in the development of a program in bioengineering, paralleling Brownell's interest.
Staff activities and professional societies. — A. H. White was an early member of the American Institute of Chemical Engineers, becoming president in 1929-30. He was active in the establishment on the Michigan campus of the first student chapter of the American Institute of Chemical Engineers in 1922, and he was president of the American Society of Engineering Education in 1942. Brown likewise was active in the Institute. He was president in 1944, and over a period of years he has contributed to the work of the constitution and the education and accrediting committees. He served as director of research for the National Dairy Products, Inc., and as director of engineering for the United States Atomic Energy Commission. A. E. White was the first president of the American Society for Metals in 1920. Later, he was president of the American Society for Testing Materials.
Members of the staff have been authors of seventeen books and more than seven hundred publications. The text Unit Operations, prepared under the leadership of Brown, appeared in 1950 and was promptly adopted by 115 institutions, including almost all departments of chemical engineering in the country.
