[86]Retired general Paul von Hindenburg (1847–1934) had been elected president of Germany on 26 April 1925 (see Berliner Tageblatt, 27 April 1925, EE). [87]The bay of Rio de Janeiro is studded with 130 islands. Félix d’Herelle, who had discovered bacteriophage in 1917, published a series of articles on phage therapy in 1921–1925, based on his experiments at the Institut Pasteur in Paris. See Summers 1999, chap. 8. [88]Einstein was greeted at the port by Rabbi Isaiah Raffalovich, Isidoro Kohn, and Daniel Hen- ninger Arthur Getúlio das Neves, Professor of Engineering at the Polytechnic School and deputy president of the Engineering Club Aloísio de Castro and several students. He was taken directly to the upscale Hotel Glória on the waterfront to rest for a while. In discussions with his reception com- mittee, it was decided that Einstein would give two lectures on the theory of relativity—one at the Engineering Club and one at the Polytechnic School—tour a number of scientific institutions, and reserve one evening for a reception with the Jewish community. His visit would also include an audi- ence with the president of Brazil, a rail journey to the city of Itatiaia in the mountains, and ample time to rest (see O Jornal, 5 May 1925, and Tolmasquim 2003, pp. 127–130). [89]Isidoro Kohn. Bavarian or Austrian slang for a braggadocio. Irma Kohn. Poldi Wettl. On their walk, Kohn suggested that they purchase a tailcoat for Einstein’s audience with the president of the Republic the next day (see Tolmasquim 2003, p. 130). [90]The German merchants invited Einstein to a meeting with representatives of the local German community. He also received an honorary doctorate of philosophy from Washington Garcia, dean of the School of Philosophy at the University of Rio de Janeiro (see Abs. 679 and diploma [65 038]). The group of professors who accompanied Einstein on his outing to Sugarloaf Mountain included Aloísio de Castro and Getúlio das Neves (see Jornal do Brasil, 6 May 1925, and Tolmasquim 2003, pp. 131 and 239). Isaiah Raffalovich. [91]Antônio da Silva Mello (1886–1973) was Professor of Clinical Medicine at the University of Rio de Janeiro and a reformer of the Brazilian medical system. They walked in the Santa Teresa neigh- borhood and had lunch at Restaurante do Minho (see Tolmasquim 2003, p. 132). [92]The president of the Republic was Artur Bernardes (1875–1955). The delegation to the presi- dent was headed by Getúlio das Neves. The meeting was primarily a courtesy visit. Toward the end of the audience, the president had to deal with suppressing a revolt by the younger generation of the Brazilian military. Einstein posed for photographs with the president and various cabinet ministers, including Minister of Justice Afonso Pena, Júnior. The Brazilian Ministry of Education was only established in 1931 (World Bank 2002, p. 65). The mayor of Rio de Janeiro was Alaor Prata Soares (1882–1964). Einstein’s first public lecture on relativity at the Engineering Club was attended by the American and Portuguese ambassadors, an admiral and several generals from the armed forces, representatives of the Ministers of Justice and Agriculture, the mayor of Rio de Janeiro, and prominent engineers and physicians. Many wives and children were also in attendance. Einstein was briefly introduced by Getúlio das Neves. He delivered the lecture in French. According to press reports, some members of the audience were seated so close to Einstein that he was pushed against the blackboard. Following his lecture, Einstein was presented with four bronze medals that commemorated the centenary of the Brazilian republic in 1922 (see O Imparcial, Jornal do Brasil, and O Jornal, 7 May 1925 Cafarelli 1979, pp. 13–14 and Tolmasquim 2003, pp. 132–135 for a translation of Einstein’s lecture into Por- tuguese, see Appendix L). [93]During his visit to the National Museum of Brazil, Einstein was greeted by the anthropologist Edgar Roquette-Pinto, since the director of the museum, Arthur Neiva, was in São Paulo at the time. Among the various objects shown to Einstein was the ten-ton Bendegó meteorite. Roquette-Pinto gave Einstein an Indian bracelet as a gift for his wife. Thereupon, Einstein allegedly asked for another one for Mileva (see O Paiz, 12 May 1925, and Glick 1999, pp. 109–110). The luncheon hosted by Aloísio de Castro was also attended by the physicians Miguel Couto and Silva Mello, Getúlio das Neves, and Daniel Henninger the Russian archeologist Alberto Childe
