The purposes of the Fritz Hüttinger Stiftung, which is legally dependent on the Berthold Leibinger Stiftung, include the advancement of science and research, especially of innovative technologies in the field of electrical energies, the promotion and nurture of community organizations and charity.

About Fritz Hüttinger

Fritz Hüttinger (1897–1963) was born in June 1897 in Appetshofen near Nördlingen, Germany. He completed an apprenticeship as an electrician and in 1919, after his service in WWI, he began his studies in the field of electro technology at the University of Engineering in Konstanz, Germany. In 1921, the young engineer arrived in Freiburg im Breisgau, where he founded a company for electrical appliances in 1922. In 1925, he expanded operations to include a factory for electronic medical devices in which the first diathermic and surgical devices were mass produced in 1926. A new building for the company’s 30 employees followed in 1933. In 1936, production began in the company’s own glass blowing of the “Hüttinger High-Vacuum Amplifier Valve” for electro-medical devices. Up until the beginning of the war in 1939, about 90 percent of production was exported.

In November 1944, all of the company’s buildings were bombed in an air raid. Fritz Hüttinger began rebuilding the company in 1946 together with several employees. As early as 1949-50, he began producing new electro-medical devices, in particular high frequency generators for inductive and capacitative heating for industrial uses. He also advanced the development of medium-frequency generators. Yet in 1963, Fritz Hüttinger died at the age of 65. His widow took on the challenge of running the company. Since 1993, 90 percent of the shares in the present Trumpf Hüttinger GmbH + Co. KG have been owned by Trumpf and 10 percent by the Ruf/Hüttinger family.

The Fritz Hüttinger Foundation is sponsoring a new endowed chair at the Institute for Sustainable Systems Engineering

One Million Euros for Energy-Efficient Radio-Frequency Electronics

The Fritz Hüttinger Foundation and the University of Freiburg have signed an endowment agreement establishing the Fritz Hüttinger Professorship for Energy-Efficient Radio-Frequency Electronics at the Institute for Sustainable Systems Engineering (INATECH). The Foundation is donating a total of one million Euros over a period of ten years for the endowed chair. The goal of the new professorship is to advance the University of Freiburg’s development of innovative technologies in the field of efficiency of electronics.


“We are deeply grateful to the donors Mrs. Gerda Ruf and Dr. Fritz Ruf for the many years of generous support of our research and teaching,” said Rector Prof. Dr. Hans-Jochen Schiewer, adding:  “We regard the Foundation’s decision to remain a close partner by funding another endowed professorship as an extraordinary sign of trust.” The University of Freiburg also granted the Rufs the titles of Honorary Senators in 2018 as a token of gratitude for their special contribution to the continued advancement of the Faculty of Engineering.


The Fritz Hüttinger Professorship will focus on engineering aspects of the energy efficiency of micro- and nano-electronic building blocks and circuits, especially those based on compound semiconductors. “The goal of research and development is to understand and optimize the efficiency and robustness of electrical components and systems in applications in fields such as energy technologies, communications technologies, security technologies, and sensor technologies,” says associate professor Dr. Rüdiger Quay from the Department of Microsystems Engineering (IMTEK) at the University of Freiburg and the Fraunhofer Institute of Applied Solid State Physics IAF, who accepted the offer of the professorship.

This thematic focus is primarily based on such emerging fields of research as fourth industrial revolution and 5G, the fifth generation technology for cellular networks that will enable a completely new level of communication and connectivity among humans, machines, and production. The scientists researching in the lab of this new professorship will thus be researching and testing sustainable electronic microsystems and intelligent materials for the Internet of Things.

Fritz-Hüttinger-Chair of Microelectronics

The Albert-Ludwigs-Universität Freiburg has named the chair of professor Yiannos Manoli for microelectronics at the Department of Microsystems Engineering “Fritz-Hüttinger-Chair of Microelectronics.” Thereby the university pays tribute to the great entrepreneurial personality of Fritz Hüttinger, the founder of Hüttinger Elekronik GmbH. The foundation will support the professorship for a period of ten years with an annual endowment of 100,000 euros.

Students and doctoral candidates at the IMTEK profit from prizes and grants, which are given to excellent young scientists in the field of electrical engineering and power electronics. Internships and field trips are also being offered.

The foundation also sponsors activities to win pupils for technical and scientific subjects. These are e.g. taster weeks at universities, partner events with schools, and workshops that help understand science and research in public reception.

NEWS: Sculpture inaugurated in Freiburg, Germany

Donated by Gerda Ruf, née Hüttinger, and her husband Dr. Fritz Ruf

Since November 2017, a sculpture of the artist Wolfgang Jakob, situated on the Robert-Grumbach-Platz in the Southern German town of Freiburg, commemorates the location of the former Hüttinger production site where frequency generators had been produced in the past. Gerda Ruf, née Hüttinger, and her husband Dr. Fritz Ruf donated the sculpture made of stainless steel and granite. It represents an inductor, resembling the ones formerly produced by the company Hüttinger and is placed on a base with the company’s milestones engraved on it.
