HIGHLIGHTS ADVANCED MATERIALS & PROCESSES | JULY/AUGUST 2024 70 IN MEMORIAM Joseph Chivinsky, 88, of Mechanicsburg, Pennsylvania, passed away on April 22. Born on July 18, 1935, he was a graduate of Mahanoy City High School. Chivinsky earned a bachelor’s degree from Penn State University, followed by a master’s from Lehigh University. He began working toward his Ph.D. at Carnegie Mellon University. Chivinsky honorably served his country in the United States Air Force. He then worked for the Bethlehem Steel Corp. as a member of the Loop Course, and later for Allegheny Ludlum Corp., where he made significant contributions as a metallurgical engineer until his retirement. Chivinsky continued to share his expertise as a consultant for the Performance Review Institute. His contributions to the field of hardness testing were recognized with ASTM’s prestigious Anthony DeBellis Award. He also held nine patents. Throughout his career, Chivinsky was an active member of ASTM, Society of Automotive Engineers, American Society of Mechanical Engineers, and ASM International. Charles Danne Graham, 94, an emeritus professor in the department of materials science and engineering at the University of Pennsylvania, died on March 18. He received a bachelor’s degree in metallurgical engineering with distinction from Cornell University and a Ph.D. in physical and theoretical metallurgy as a Fulbright Scholar at the University of Birmingham. He worked as a research metallurgist at the New York-based General Electric Research and Development Center, where he was named a John Simon Guggenheim Memorial Foundation Fellow in 1961. Graham first came to Penn as a visiting professor in 1969. He joined the faculty in 1970 as a professor in what was then named the department of metallurgy and materials science in Penn Engineering. He served as chair of the department from 1979 to 1984. Graham retired and took emeritus status in 1997. His research focused on magnetic materials and measurements, domain structure, amorphous alloys, and permanent magnets. He authored over 120 papers and book chapters and held several patents. Todd Allen Leonhardt of Cleveland died on May 29 at the age of 62. Born in New Castle, Pennsylvania, Leonhardt received degrees in metallurgical technology and chemistry from Pennsylvania State University and Baldwin Wallace University, respectively. He most recently served as director of research and development and chief metallurgist for Ohio-based Rhenium Alloys Inc. An expert on high-temperature refractory metals, Leonhardt spent more than 25 years working with rhenium and rhenium-containing alloys. Additionally, he worked for nearly four decades developing industrial and government research experience in the areas of materials characterization and process metallurgy of refractory metals. Leonhardt published over two dozen pieces of research, including a NASA technical memorandum, peer-reviewed journal articles, and conference proceedings. He was a past director and past president of the Refractory Metals Association, as well as an active member of the Metal Powder Industries Federation, the Minerals, Metals & Materials Society, and ASTM International technical organizations. He was a longtime member of ASM International and its Cleveland Chapter. I NI NMME EMMOORRI AI AMM Chivinsky Leonhardt
