although not for Einstein himself, but in support of the planned the Hebrew
University of
Jerusalem.[44]

[13]“Professor Einstein ist gerade im gegenwärtigen Augenblick für Deutschland ein Kulturfaktor
ersten Ranges, da Einsteins Name in weitesten Kreisen bekannt ist. Wir sollten einen solchen Mann,
mit dem wir wirkliche Kulturpropaganda treiben können, nicht aus Deutschland vertreiben.”

[14]Prominent among these was the murder of Hans Paasche, a former naval officer turned pacifist,
in May 1920. Friedrich Wilhelm Förster, of the ethics faculty at the University of Munich, and Georg
Friedrich Nicolai, of the medical faculty at the University of Berlin, were both fired. For Einstein’s
public statement in defense of Nicolai, see Vol. 7, Doc. 32.
[15]The votes for the Weimar coalition dropped to 11 million from 19 million in the previous elec-
tions, held in January 1919. Votes for parties on the right increased from 5.6 to 9.1 million, and for
parties on the left from 2.1 to 5.3 million. On 4 August 1920, amnesty was granted to the participants
in the Kapp Putsch who were not instigators or leaders. On 11 August 1920, when the Disarmament
Law came into force, the Bavarian government refused to disarm the Bavarian Home Guards. See
