[46]Under the headline “Germany Disarms as Little as She Can” (“L’Allemagne désarme le moins
qu’elle peut”), the statement was allegedly written and delivered in person by Otto Lehmann-
Russbüldt to the special correspondent of Le Matin in Berlin. “[O]n behalf of the Bund ‘Neues Vater-
land,’” Lehmann-Russbüldt conveyed “information on the issue of the disarmament of the ‘Sipo’
Sicherheitspolizei [security police] and on the Einwohnerwehr [citizens’ guard].” The statement
accused Wilhelm Peters, the Reichs commissioner for the disarmament of the civilian population, of
willfully ignoring available information about the weapons caches of private citizens, and in effect
asked for France’s help to avert the threat of a future war: “To give up on the question of disarmament,
even to a small extent, would be to relinquish the republican and democratic Germany to the tyranny
of the exasperated ‘junkers’ and to leave an open field for the preparation for a new war to the propo-
nents of revenge. We hope that France will know to protect us against these two perils.” At the Allied-
German Conference in the Belgian town of Spa in July 1920, Germany had been ordered, and had
agreed, to dissolve the Sicherheitspolizei and to disarm the Einwohnerwehr (see International Year-
book 1921, p. 732).

as a future prototype of a communist front organization.

[54]The argument was later published in Einstein and Grommer 1923.
[55]A similar consideration can be found in two documents from late 1920, Einstein to Paul Ehren-
fest, ca. 9 December 1920 (Vol. 10, Doc. 227), and Vol. 10, Appendix.

[57]When finally completed in 1925, Michelson's novel experiment would once again confirm the
relativistic (or stationary ether) predictions. Michelson and Gale 1925.
[58]Hentschel 1993 sees St. John as still being a skeptic in 1921, and of “converting” only in 1923.

[61]In his proposal, presented to the Academy on 8 December (Vol. 7, Doc. 68), Einstein only men-
tions Hans Geiger as his experimentalist collaborator. There is evidence that as early as 7 December,
Walther Bothe was expressing interest in the details of the theory and the experimental design of the
project (Doc. 316).

[63]The paper was read by Paul Ehrenfest, since Bohr could not attend due to illness (see Bohr
