Max Dehn (1878-1952) was a German mathematician known for his contributions to geometry, topology, group theory, and the history of mathematics. Born in Hamburg, Germany, he studied mathematics in Freiburg and Göttingen, where he earned his doctorate under the supervision of David Hilbert in 1900. In 1901, he solved Hilbert's third problem, posed at the International Congress of Mathematicians. Dehn began his teaching career at the University of Münster in 1901, and, after teaching at several institutions, he landed at Frankfurt University (1921-1935). In 1935, the Nazis forced him to leave his post; he and his wife fled Europe for the United States in 1941. After teaching in several universities, he found a permanent position at Black Mountain College in North Carolina in 1945. Dehn remained at the college until he retired in 1952.

The Max Dehn Papers document the career of Max Dehn (1878-1952) and relate chiefly to his research in geometry, topology, group theory, and the history of mathematics. Most of the papers are from Dehn's years at Frankfurt University and, after his immigration in 1940 to the United States, Black Mountain College in North Carolina. Included are correspondence, notebooks, manuscripts of publications, reprints, lecture and course notes by Dehn, remembrances written by his daughter, colleagues and students, and lecture notes by Ernst Hellinger. Correspondents include Emil Artin, Otto Blumenthal, Harald Bohr, Samson Breuer, Constantin Carathéodory, David Hilbert, Adolf Kneser, Emmy Noether, Moritz Pasch, Otto Toeplitz, and Ernst Zermelo. The majority of the materials are written in German, with some English and French.

Serial numbers were assigned to shipments that arrived at the HRC before the collection was transferred to the Briscoe Center in 1984. Although the material has been rearranged, the original serial numbers have been placed in brackets on the folders for the convenience of researchers who are familiar with the original inventory.
