Max Planck Society

The Max Planck Society for the Advancement of Science (German: Max-Planck-Gesellschaft zur Förderung der Wissenschaften e. V.; MPG) is a formally independent non-governmental and non-profit association of German research institutes. Founded in 1911 as the Kaiser Wilhelm Society, it was renamed to the Max Planck Society in 1948 in honor of its former president, theoretical physicist Max Planck. The society is funded by the federal and state governments of Germany.

According to its primary goal, the Max Planck Society supports fundamental research in the natural, life and social sciences, the arts and humanities in its 84 (as of January 2024) institutes and research facilities. As of 31 December 2023^[update], the society has a total staff of 24,655 permanent employees, including 6,688 contractually employed scientists, 3,444 doctoral candidates, and 3,203 guest scientists. 44.9% of all employees are female and 57.2% of the scientists are foreign nationals. The society's budget for 2023 was about €2.1 billion.

The Max Planck Society has a world-leading reputation as a science and technology research organization, with 39 Nobel Prizes awarded to their scientists, and is widely regarded as one of the foremost basic research organizations in the world. In 2020, the Nature Index placed the Max Planck Institutes third worldwide in terms of research published in Nature journals (after the Chinese Academy of Sciences and Harvard University). In terms of total research volume (unweighted by citations or impact), the Max Planck Society is only outranked by the Chinese Academy of Sciences, the Russian Academy of Sciences and Harvard University in the Times Higher Education institutional rankings. The Thomson Reuters-Science Watch website placed the Max Planck Society as the second leading research organization worldwide following Harvard University in terms of the impact of the produced research over science fields.

The Max Planck Society and its predecessor Kaiser Wilhelm Society hosted several renowned scientists in their fields, including Otto Hahn, Werner Heisenberg, and Albert Einstein.

The Max Planck Society also hosts the Cornell, Maryland, and Max Planck Pre-Doctoral Research School, an intense week of lectures, informal conversations with guest faculty and fellow students from all over the world, professional development panels with academic and industrial speakers, research poster sessions, and social events.

The organization was established in 1911 as the Kaiser Wilhelm Society, or Kaiser-Wilhelm-Gesellschaft (KWG), a non-governmental research organization named for the then German emperor. The KWG was one of the world's leading research organizations; its board of directors included scientists like Walther Bothe, Peter Debye, Albert Einstein, and Fritz Haber. In 1946, Otto Hahn assumed the position of president of KWG, and in 1948, the society was renamed the Max Planck Society (MPG) after its former president (1930–37) Max Planck, who died in 1947.

The Max Planck Society has a world-leading reputation as a science and technology research organization. In 2006, the Times Higher Education Supplement rankings of non-university research institutions (based on international peer review by academics) placed the Max Planck Society as No.1 in the world for science research, and No.3 in technology research (behind AT&T Corporation and the Argonne National Laboratory in the United States).
