Lorenz retired in 2000 as a Professor from the University of Magdeburg after serving on the faculty since 1970. In 2015, Lorenz received the Fakultaetspreis (faculty award) given by the Faculty of Informatics (Computer Science) at the University of Magdeburg in recognition of his outstanding performance as Founding Dean of Informatics (1990-1992) and as co-founder of the Institute of Simulation and Graphics (1993). He also founded a conference on simulation, held annually at the University of Magdeburg from 1982-2007. In the mid-1990s, Lorenz became a member of the management board of the German simulation society, ASIM. A 1979 German textbook, co-authored by Lorenz: Simulation Diskrete Prozesse, was used by several universities in East Germany. He authored The Science of Remote Visual Inspection (RVI): Technology Applications Equipment (1990). Among his numerous published papers are several about simulation and animation that appeared in Proceedings of the annual Winter Simulation Conferences.
