Berthold Leibinger (26 November 1930 – 16 October 2018) was a German engineer, entrepreneur and philanthropist best known for his long association with the machine tool and laser company TRUMPF. Under his leadership the firm expanded from a regional machine-builder into a recognized global supplier of industrial lasers and automated metalworking systems. He combined technical expertise with strategic management and remained an influential figure in German industry.
Career and technical influence
Trained as an engineer, Leibinger played a central role in adapting laser technology for industrial manufacturing processes, including cutting and welding. He emphasised applied research and close cooperation between engineering teams and production, which helped translate laboratory developments into robust commercial systems. His approach stressed reliability, automation and practical integration rather than experimental prototype work alone.
Leadership and roles
As head of TRUMPF, Leibinger guided business expansion, export growth and product diversification. He served on supervisory and advisory boards in industry and was widely consulted for his experience in technology-driven entrepreneurship. The University of Stuttgart recognised his contributions to engineering and business with an honorary doctorate.
Philanthropy and the Berthold Leibinger Stiftung
Beyond business, Leibinger established the Berthold Leibinger Stiftung, a non-profit foundation dedicated to promoting science, culture and education. The foundation supports research projects, awards prizes in applied laser technology and fosters cultural initiatives. His philanthropic activities reflected a commitment to transferring technological advances into societal benefit.
Legacy, distinctions and notable facts
- Instrumental in making laser-based metalworking an industrial standard rather than a niche research topic.
- Combined engineering leadership with active business strategy to scale manufacturing technologies globally.
- Recognised with academic honours and invited to advise other enterprises across sectors.
Leibinger remained engaged with scientific and civic causes until his final years. He died in Stuttgart of complications related to Alzheimer’s disease on 16 October 2018 at the age of 87. For contemporary responses and remembrances see contemporary accounts and local reporting from Stuttgart.
His life is often cited as an example of how sustained investment in applied engineering and close ties between research and manufacturing can create enduring industrial capability while also enabling philanthropic support for science and culture.
