Gene began his long and illustrious career at Cincinnati Milling Company in 1936. After the retirement of Hans Ernst, Gene became the Director of Physical Research, where he created a world-class research laboratory to investigate various manufacturing processes. Later on in the early 1960s, as Milacron's Principal Scientist for Manufacturing Research, Gene took a visionary role of integrating computers with manufacturing and design with manufacturing, at a time when computers were in their infancy and software development was extremely difficult. In 1983, at age 70, Gene retired from Milacron and joined Metcut Research Associates. From 1990, Gene joined TechSolve (formerly the Institute of Advanced Manufacturing Sciences (IAMS), a non-profit, manufacturing consulting firm in Cincinnati) as a senior consultant, a role he played until the very end. In the following, five of Gene's pioneering contributions, namely, to tribology, to the basic mechanics of metal cutting, to computer integrated manufacturing (CIM), to the globalization of manufacturing, and to the environmental and human aspects of manufacturing, will be briefly summarized.
