An experiment on monochromatic light emission that appears similar to the earlier canal ray experiment and may be related to Einstein’s idea here is sketched in Doc. 182. [24]The large delegation that greeted Einstein at the port consisted of prominent members of the local Jewish community, including Rabbi Isaiah Raffalovich (1870–1956), spiritual leader of the Jewish community of Rio de Janeiro and director of ICA in Brazil, and Isidoro Elyseo Kohn (1877– 1965), an Austrian-born businessman and president of the Jewish community. The scientific welcom- ing committee was headed by the astronomer Henrique Morize and included the mathematicians Ignácio do Amaral and Roberto Marinho de Azevedo Paulo de Frontin, director of the Polytechnic School Aloísio de Castro (1881–1959), chairman of the Faculty of Medicine at the University of Rio de Janeiro and member of the International Committee on Intellectual Cooperation and the German- born chemist Daniel Henninger. Numerous journalists were also in attendance, including one from A Noite, who interviewed Einstein and asked him to write a note on a greeting card (see Abs. 669). The welcoming committee invited Einstein to tour the city by car. In the convoy of seven cars, Ein- stein was accompanied by Rabbi Raffalovich (see Tolmasquim 2003, pp. 70 and 232, and Glick 1999, pp. 104–105). [25]Einstein was greeted by the director of the Research Institute at the Botanical Gardens of Rio de Janeiro, Antonio Pacheco Leão, and entered a note in the visitors’ log (see Abs. 666). Following the tour of the gardens, Einstein lunched at the recently constructed Copacabana Palace Hotel, hosted by Assis Chateaubriand, owner of the newspaper O Jornal. Other guests included Eduardo Horovitz, secretary of the Zionist Federation Leon Schwartz, president of the Hebrew College and Emanuel Galano, president of the Bnei Herzl. Following lunch, Einstein went for a walk (see O Jornal, Paiz and A Noitre, 21 and 22 March 1925 and Glick 1999, p. 104). [26]Mauricio Nirenstein. A small group of Argentinian academics headed by Nirenstein came to greet Einstein upon his arrival in Montevideo and travel with him across the River Plate to Buenos Aires. The other prominent member of the group was the civil engineer Enrique Butty (Ortiz 1995, p. 99). [27]For a comprehensive list of the Jewish organizations represented at the harbor to greet Einstein, see Ortiz 1995, p. 107, note 125. A joint Jewish reception committee was established whose members were Sansón Raskowky, David Groisman, León Horischnik, L. Minuchin, and Luis Sverdlick (see Ortiz 1995, p. 108). [28]Bruno Wassermann (1874–1940) was a German-Jewish paper merchant. The Wassermanns’ house was located in the elegant neighborhood of Belgrano. [29]Leopoldo Lugones (see note 43) visited Einstein on his first day in Buenos Aires (see Ortiz 1995, p. 100). The German ambassador was Carl Gneist (1868–1939). [30]The rector was José Arce (1881–1968), Professor of Anatomy and Surgery and a politician. The dean of the faculty of exact, physical, and natural sciences was Eduardo Huergo (1873–1929), Pro- fessor of Civil Engineering. [31]Einstein gave extensive interviews to reporters of La Nación and Crítica. On his tour of the city, he visited the parks of the Palermo neighborhood and the fruit and vegetable market at the Abasto (Ortiz 1995, p. 100). [32]Julio R. Castiñeiras (1885–1944) and his wife, Delia O. Miguel de Castiñeiras. [33]Berlin dialect for “Nase voll.” [34]During his tour of the United States, Einstein had participated in numerous events hosted by Jewish organizations and had subsequently expressed some disenchantment with his fellow Jews (see Vol. 12, Introduction, pp. xxxii–xxxiv, and Einstein to Michele Besso, before 30 May 1921 [Vol. 12, Doc. 141]). [35]The reception and introductory public lecture were held on 27 March at the main auditorium of the Colegio Nacional de Buenos Aires, a prestigious high school affiliated with the university. The lecture lasted approximately half an hour and dealt with inertial reference systems, the physical exper- iments performed to verify the principle of relativity, and the problems raised by concepts of absolute space and ether. The lecture was delivered to a “wide and heterogeneous university audience” that included government ministers, foreign ambassadors, teachers, and students. At the podium were
