Pièce 39-42 - 'R. Frisch Eigene Briefe bis Oct. 1933' folder

The letters are Frisch's carbons only, in date order; those from 22 January-27 October 1930 are sent from Berlin, those from 11 November - 7 August 1933 are from Hamburg, and there is one letter, 28 September 1933, from Copenhagen immediately before Frisch's departure for England.

The correspondence constitutes a record of all Frisch's affairs, including family letters, research and publications, personal friends, etc. The letters to Frisch's parents ('Schnumpunzel' and 'Bavitschkerl') and to Lise Meitner ('Tanterl') should be consulted in association with the incoming family correspondence in Series A.

Identifiable correspondents are indexed, but many are addressed either by a nickname or in formal terms such as 'Herr Professor', 'Herr Kollege'.
