Otto Meyer-Amden / Hermann Huber Fonds
In the early 1980s, the family of Hermann Huber (1888–1967) gave SIK-ISEA the correspondence between Otto Meyer-Amden (1885–1933) and Hermann Huber, which is of tremendous value to researchers. More than 300 letters from Meyer-Amden and over 60 letters from Huber have survived.
