We remember Prof. em. Dr.-Ing. Hartmut Weule, a distinguished engineering scientist who uniquely bridged academia and industry. Born on October 1, 1940, he studied mechanical engineering at the Technical University of Braunschweig, earning his doctorate with distinction in 1972. Following his early innovations at Daimler-Benz, he became a professor at the University of Karlsruhe, where he developed influential concepts in production engineering education. He then returned to Daimler-Benz as a board member of research and technology and played a key role in integrating major research divisions and pioneering fuel cell vehicle development. He later promoted the internationalization of the University of Karlsruhe through initiatives such as the International Department and the Hector programs, which support talented students and researchers. Honored with numerous awards, including the Federal Cross of Merit, he leaves behind a lasting legacy of excellence, vision, and quiet dedication.
