MARS G. FONTANA received a bachelor's degree in Chemical Engineering in June 1931 and his master's, September 1932, and Ph.D., January 1935, in Metallurgical Engineering, all from the University of Michigan. He was a research assistant in the Department of Engineering Research 1929-1934. From October 1934 through October 1945, he was a metallurgical engineer and supervisor, Engineering Department, E. I. duPont de Nemours and Co., Wilmington, Del. In addition to corrosion and other metallurgical problems, he pioneered industrial uses of nylon, teflon, and other nonmetallics, and while associated with DuPont, he developed patents on corrosion indicating, recording and testing devices. He joined the staff at Ohio State in November 1945. In addition to his position as Chairman of the Department of Metallurgical Engineering he was named Ohio Regent's Professor in 1967, Duriron Professor in 1970, and is Director of the Corrosion Center which is the largest university effort in corrosion in the country. He was president of the National Association of Corrosion Engineers in 1952 and N.A.C.E. presented him with the Frank Newman Speller Award in Corrosion Engineering in 1956. He is editor of the journal CORROSION since it started its new format in 1962. He was chairman of the Corrosion Division of the Electrochemical Society in 1948. He received the Distinguished Engineering Alumnus Citation in 1953 and the Sesquicentennial Award in 1967 from the University of Michigan. He was elected to the National Academy of Engineering in 1967. In 1969 he received honorary membership to the American Society for Metals. METALLURGICAL TRANSACT|ONS
