He was the Swiss Federal Councillor (Bundesrat) for Postal Affairs and Railroads, responsible for the Swiss Telegraph Administration in which Chavan was employed. See Doc. 271 for Forrer's involvement in the controversy at the Swiss Telegraph Administration. 261. To Conrad Habicht [Munich, 2 April 1911][1] Es ging gut. Heute kamen wir heiler Haut in München an.- Ich danke Ih- nen, auch im Namen meiner Frau herzlich für Ihre Gastfreundschaft[2] und dem braven und doch so schlauen Hofprediger für die vortrefflichen Zigarren. Mit den besten Grüssen Ihr A. Einstein [. . .][3] AKS (Walter Habicht, Rodersdorf, Switzerland). [12 470]. The postcard is addressed "Familie Habicht Fulacherstr. 18. Schaffhausen." The postmark is completely obscured.

[2]On their journey to Prague via Munich Mileva Einstein-Maric and Einstein may have passed through Schaffhausen, where Habicht's parents lived. [3]A postscript by Mileva Einstein-Maric is omitted.
