The Fraunhofer-Gesellschaft, commonly known in English as the Fraunhofer Society, is a German organization dedicated to applied research. It includes 75 institutes and research units, each focusing on different research fields. With some 32,000 employees, mainly scientists and engineers, and an annual research budget of approximately , it is one of the world's leading organizations for applied research. The organization, headquartered in Munich, is named after Joseph von Fraunhofer, who, as a scientist, engineer and entrepreneur, is said to have superbly exemplified the goals of Fraunhofer. Since the 1990s the organization has also internationalized, establishing various centers and representative offices in Europe, the United States, Asia and South America.
Fraunhofer model Under the Fraunhofer model, which was approved in 1973, the Fraunhofer-Gesellschaft earns about two thirds of its income through contracts with industry or specific government projects. The remaining third of the budget is sourced in the proportion 9:1 from federal and state government grants and is used to support pre-competitive research.
Thus the size of Fraunhofer's budget depends largely on its success in maximizing revenue from contract research.
The institutes are not legally independent units. However, the Fraunhofer model grants a very high degree of independence to the institutes in terms of project results and scientific impact and above all for their own funding. On the one hand, this results in a high degree of independence in terms of technical focus, distribution of resources, project acquisition and project management. On the other hand, this also generates a certain economic pressure and a compulsion to customer and market orientation. In this sense, the institutes and their employees act in an entrepreneurial manner and ideally combine research, innovation and entrepreneurship.
Numerous innovations are the result of research and development work at the Fraunhofer institutes. The institutes work on practically all application-relevant technology fields, including microelectronics, information and communications technology, life sciences, materials science, energy technology or medical technology. One of the best known Fraunhofer developments is the MP3 audio data compression process. In 2024, the Fraunhofer-Gesellschaft reported 507 new inventions. Of these, 439 patent applications claiming rights of priority were filed. The number of active patent families amounted to 7,081. Studies in 2023 have shown that the presence of a Fraunhofer center can boost the patent output of local firms and inventors by at least 13%.

Notable projects The MP3 compression algorithm, which was invented and patented by the Fraunhofer Institute for Integrated Circuits IIS. Its license revenues generated about 100 million euros in revenue for Fraunhofer in 2005. The H.264/MPEG-4 AVC video compression standard, to which the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute, HHI was a significant contributor. The technology was recognized with two Emmy awards in 2008 and 2009. This includes the Fraunhofer FDK AAC library. A metamorphic triple-junction solar cell developed by the Fraunhofer Institute for Solar Energy Systems ISE. As of May 2010, it holds the world record for solar energy conversion efficiency with 41.1%, nearly twice that of a standard silicon-based cell. E-puzzler, a pattern-recognition machine to digitally put back together even the most finely shredded papers. It uses a computerized conveyor belt that runs shards of shredded and torn paper through a digital scanner, automatically reconstructing original documents. It was hoped in 2013 that the machine would be able to reconstruct 16,000 bags of torn-up documents, but by 2014 only 23 bags had been reconstructed and the project stalled. In 2024 faster technology was being sought to prepare the vast number of fragments for scanning. OpenIMS, an open source implementation of IMS Call Session Control Functions (CSCFs) and a lightweight Home Subscriber Server (HSS), which together form the core elements of all IMS/NGN architectures as specified today within 3GPP, 3GPP2, ETSI TISPAN and the PacketCable initiative.

History
Fraunhofer was founded in Munich on March 26, 1949, by representatives of industry and academia and the governments of Bavaria, Hesse and Württemberg. In 1952, the German Federal Ministry for Economic Affairs declared the Fraunhofer-Gesellschaft to be the third part of the non-university German research landscape (alongside the German Research Foundation and the Max Planck institutes). From 1954, Fraunhofer's first institutes were established. By 1956, it was also providing administrative assistance in the area of defence research in collaboration with the German Federal Ministry of Defense. In 1959, the Fraunhofer-Gesellschaft comprised nine institutes with 135 employees and a budget of .
In 1968, Fraunhofer became the target of public criticism for its role in military research. By 1969, Fraunhofer had more than 1,200 employees in 19 institutes, with a budget of . At this time, a commission for the promotion of the development of the Fraunhofer-Gesellschaft planned the further development of the Fraunhofer-Gesellschaft. In 1972, it proposed a financing model that would make Fraunhofer dependent on its commercial success. This would later come to be known as the Fraunhofer model. The model was agreed to by the federal cabinet and the Joint Commission of the Federal and States Governments (Bund-Länder-Komission) in 1973. In the same year, the executive board and central administration moved into joint accommodation at Leonrodstrasse 54 in Munich.
In 1977, a general agreement on research promotion came into force stipulating that the political ownership of Fraunhofer would be shared by the German Federal Ministries of Defense and Research. In 1984, Fraunhofer had 3,500 employees in 33 institutes and a research budget of . Five years later, in 1989, the number of employees had increased to nearly 6,400, with Fraunhofer operating 37 institutes with a total budget of . In 1991, Fraunhofer faced the challenge of integrating numerous research establishments in former East Germany. By 1993, Fraunhofer's total budget exceeded . In 1994, Fraunhofer USA, Inc., was founded to manage the activities of the Fraunhofer-Gesellschaft in the U.S.
