Abstract

To compile a comprehensive edition of the correspondence of the world-famous physicist, physiologist, philosopher, and pioneer historian of science, Ernst Mach is an urgent desideratum. An estimated 5000 letters to and from Mach are kept in public and private archives worldwide. The largest part of this correspondence was formerly kept in the Ernst Mach Institut für Kurzzeitdynamik der Fraunhofergesellschaft in Freiburg/Breisgau and is now archived at the Deutsches Museum in Munich. A smaller partial estate, based on collections by Ernst Mach’s son Ludwig has been transferred to the Staats- und Universitätsbibliothek Göttingen. Other major collections are kept in Konstanz, Vienna, Prague etc. Mach’s own letters are spread throughout Europe and North America in hundreds of archives hosting private papers or estates of his contacts.
