Peter Mittelstaedt pseudonym Karl Rottmann (born November 24, 1929 in Leipzig - November 21, 2014 in Erftstadt), was a German physicist, philosopher, and scientific theorist.[1][2][3]
After studying physics at the universities of Jena, Bonn, and Göttingen, with a doctorate in theoretical physics in Göttingen in 1956 with Werner Heisenberg, Mittelstaedt had research stays at CERN in Geneva and at MIT in Cambridge, USA and at the then Max Planck Institute for Physics and Astrophysics in Munich, where he also completed his habilitation in 1961. In 1965, Mittelstaedt became a Professor of Theoretical Physics at the University of Cologne, his main areas of work were philosophy of natural science, philosophy of science, and logic as well as the basics of relativity and quantum theory. In 1968, and 1969 he was Dean of the Faculty of Mathematics and Natural Sciences, Rector of the University in 1970 and 1971, Vice-Rector from 1971 to 1973, and later Vice-Rector for Research in Cologne. Mittelstaedt retired in 1995. He was also chairman of the board of directors of the publishing house Bibliographisches Institut. Mittelstaedt died at the age of 84 and was buried in Erftstadt-Lechenich on November 29, 2014 after a memorial service.
He is known for monographs on physics philosophy, where he was influenced by Paul Lorenzen and his operationalism and pursued a justification of quantum mechanics via quantum logic, for which he tried to provide a physical interpretation in his later work.[4]
His total of 30 students,[5] who received their doctorate from 1966–1997 with him in Cologne, included Julian Barbour, Hubertus von Grünberg, Wolfgang Hillebrandt, Heinz-Erich Wichmann, Ernst-Walther Stachow,[6]Franz Josef Burghardt, Hans-Joachim Blome[7] and Paul Busch.[8]
His grandfather was the lawyer at the Imperial Court of Justice Johannes Mittelstaedt and his great-grandfather was the Imperial Judicial Councilor and journalist Otto Mittelstaedt (1834–1899).
