HIGHLIGHTS ADVANCED MATERIALS & PROCESSES | APRIL 2025 64 IN MEMORIAM IN MEMORIAM William Warren Gerberich, FASM, P.E., professor emeritus of chemical engineering and materials science at the University of Minnesota, passed away on October 11, 2024. He was born in Wooster, Ohio, in 1935, and was educated at the Case Institute of Technology (B.S.), Syracuse University (M.S.), and the University of California, Berkeley (Ph.D.). He began his career in 1959 at the Jet Propulsion Laboratory in Pasadena, California, where he worked on NASArelated research, including application of materials for moon explorations. This was followed by experiences at Ford Aeronutronic in Newport Beach, California, and Aerojet General Corp. in Sacramento, California. Following completion of his doctoral degree, Gerberich accepted a faculty position at the University of Minnesota in 1971. This led to a distinguished 44-year academic career, resulting in over 500 publications associated with his extensive research program. Later consulting work led to many interesting materials integrity investigations, including projects such as the World Trade Center during its construction, pipeline failures, and investigations at the national laboratories. Gerberich was a member of the ASM Minnesota Chapter. Richard “Dick” E. Haimbaugh, age 89, of The Villages, Florida, formerly of Grayslake, Illinois, passed away on February 13. He was born and raised in Rochester, Indiana, and later moved to Elmhurst, Illinois, where he attended York Community High School. He went on to pursue higher education, earning his bachelors of science in metallurgical engineering in 1953 from the University of Illinois. After completing his degree, Haimbaugh began his career in the Allison Division of General Motors before serving in the U.S. Army where he worked as a mechanical engineer in the Army Rocket Guided Missile section at Redstone Arsenal. Upon leaving the Army, he attended The University of Chicago and earned an MBA degree. Eventually his career led him to teach a course on practical induction heat treating at ASM’s headquarters. In addition, he authored the ASM book, Practical Induction Heat Treating, Second Edition. In 2008, ASM held the “Richard E. Haimbaugh Symposium” honoring him for his years of service to the ASM Heat Treating Society. Haimbaugh was also a lifetime member of ASM International as well as a member of the ASM Failure Analysis Society and the ASM Chicago Chapter. Paul Martin Machmeier, FASM, of Racine, Wisconsin, died on December 18, 2024, at the age of 87. He was born in Milwaukee on May 23, 1937. Machmeier graduated from Wisconsin Lutheran High School in 1955, then attended the University of Missouri–Rolla where he earned an engineering degree. He went on to earn a Ph.D. in metallurgical engineering from Lehigh University. Machmeier developed and patented AF1410, a high-alloy, low-carbon steel known for its high strength, toughness, and stress corrosion resistance, and often used in aerospace applications. He developed AF1410 while working at the General Dynamics Fort Worth Division. He went on to work at Snap-on Tools in Kenosha, Wisconsin, where he was the manager of materials and process engineering. Machmeier was a member of the ASM Failure Analysis Society. Robert Hall Wagoner II, FASM, of Powell, Ohio, and Sarasota, Florida, died on January 28 in Cusco, Peru. Born on January 8, 1952, in Columbus, Ohio, Wagoner studied metallurgy at The Ohio State University, receiving his Ph.D. in metallurgical engineering in 1976. He then began his career at General Motors in Warren, Michigan. In 1983, Wagoner became an Ohio State faculty member in the department of materials science and engineering. He was named the George R. Smith Chair in Engineering in 2001 for his contributions to engineering education and research, a title he held until 2012. He remained an emeritus faculty member after retiring in 2013. Wagoner was inducted into the National Academy of Engineering in 1995. Haimbaugh Gerberich Machmeier Wagoner
