On May 8, 2020, Professor Emeritus Stefanos A. Paipetis passed away at the age of 82 after a short fight with heart illness. He served the University of Patras from many positions, as a member of the Rectorate Board, the Chairman of the Mechanical Engineering and Aeronautics Department Faculty Board and many other Committees. Prof Paipetis broad research reached across disciplines and captivated both students and faculty with his insight and enthusiasm. His immense and rich work has influenced the research of many of us and has shaped several generations of researchers worldwide, not only in Greece. He was a distinguished member of IFToMM Greece and his contribution in Mechanics, mechanics of materials, fracture mechanics, Vibration, and the History of Technology is highly esteemed. He is the author of numerous papers and books on a vast area of research issues in engineering, along with a wealth of works on history, poetry, and art. A keen interest in the origins of technology in the ancient world, and the contribution of ancient inventions in the progress of human society can be traced in the books and Conference Proceedings that Prof Paipetis has edited during his lifelong career of service and leadership at the University of Patras. We are all immeasurably grateful for all he has given to us through his lifetime in the IFToMM federation since its very beginning, both institutionally and scientifically, as well as personally. He is survived by his wife Potoula, philologist, daughter Alexandra, and two sons Alkis, Professor at the University of Ioannina, Greece, Makis, a grandson, and a granddaughter.
