D O C . 1 9 R E S I G N A T I O N F R O M I C I C 4 5 Published in Die Friedens-Warte 23 (1923): 186. An English version was published in the New York Times, 28 June 1923. Dated by the reference in the document to Lorentz’s appointment to the Inter- national Committee on Intellectual Cooperation (see note 4). In March, Einstein had informed Pierre Comert, the League of Nations’ press chief, of his wish to be struck from the list of members of the International Committee on Intellectual Cooperation (ICIC) (see Einstein to Pierre Comert, 21 March 1923 [Vol. 13, Doc. 447]). A veiled reference to the French and Belgian occupation of the Ruhr region, which Einstein sim- ilarly implied had led to his resignation from the ICIC two months earlier (see Doc. 10). Hendrik A. Lorentz had been appointed a member of the committee on 23 April 1923 (see League Yearbook 1924, p. 134).
