D O C . 3 7 9 T R A V E L D I A R Y 5 8 7 At 12:30 P.M., Einstein visited the Alumni Association of Engineers and Architects, which was the alumni association of the Catholic Institute of Arts and Industries. Einstein gave a brief address in French on the finite nature of the universe (see ABC and El Noticiero, 9 March 1923, and Glick 1988, pp. 141–142). His talk was attended by the deputy Spanish minister for economic development. Ein- stein was elected an honorary member of the association (for the diploma, see Abs. 532). At 6 P.M., Einstein’s fourth lecture was held at the Madrid Athenaeum, a literary-scientific club and national university. Its topic was the philosophical consequences of relativity. The event was pre- sided over by the endocrinologist Gregorio Marañon. Einstein was introduced by the marine biologist Odón de Buen, who suggested that their guest lead a joint Spanish-Mexican scientific expedition to observe the upcoming solar eclipse in Mexico (see La Voz, 9 March 1923, and Glick 1988, pp. 142– 143). For Einstein’s speech see ABC and El Heraldo de Madrid, 9 March 1923, and Glick 1988, pp. 143–144. The director of the Madrid Conservatory was Antonio Fernandez Bordas (1870–1950). [267]The Einsteins toured the historical royal palace and monastery El Escorial, approximately 45 kilometers northwest of Madrid, and the Castle of the Mendoza in the town of Manzanares el Real, approximately 60 kilometers northwest of Madrid. At 6 P.M., Einstein attended a public tribute in his honor at the Residencia de Estudiantes, a resi- dential college at the Universidad Central. In his remarks, Ortega y Gasset expounded on Einstein’s role within the context of science in Western culture and compared him to Newton and Galileo. He also stated that he viewed relativity as the seed of a new culture (see El Sol, 10 March 1923 Glick 1988, pp. 144 and 161–163 and Sánchez Ron and Romero de Pablos 2005, p. 53). In his reply, Ein- stein tried to play down the significance of his theoretical innovations, stating that he was “more of a traditionalist than an innovator” (“soy más un tradicionalista que un innovador”). He also allegedly stated that “relativity had not changed anything but had reconciled facts that were irreconcilable by the usual methods” (“La relatividad no ha cambiado nada. Ha reconciliado hechos que eran irrecon- ciliables por métodos habituales” El Sol, 10 March 1923). [268]Diego Velázquez (1599–1660). El Greco (1541–1614). Wilhelm Ullmann, director of the Deutsche Bank in Madrid, and Thyra Ullmann-Ekwall (1881–1982), a Swedish-born painter. For the invitation to lunch with Langwerth von Simmern, see Abs. 530. [269]Francisco Goya (1746–1828), Raffaello Santi (1483–1520), and Fra Angelico (c. 1395–1455). [270]At 3 P.M., Einstein was met at the station in Zaragoza by a delegation headed by University of Zaragoza physicist Jerónimo Vecino, who had initiated the visit. Also in attendance were the univer- sity’s rector, Ricardo Royo-Villanova, the university’s secretary-general, Inocencio Jimenez the chemist Antonio de Gregorio-Rocasolano y Turmo and professors of the faculty of medicine the Ger- man consul, Gustav Freudenthal, and his daughter Mayor Basilio Ferrandez Milagro and the chief of public works, Miguel Mantecón. Upon his arrival, he was driven in the mayor’s car to the Hotel Universo-Cuatro Naciones (see Sánchez Ron and Romero de Pablos 2005, p. 119). Einstein gave two lectures in Zaragoza. Both were held in French in the auditorium of the Faculty of Medicine and Sciences. The first lecture, on special relativity, was held on 12 March at 6 P.M. The hall was filled to capacity. Following the lecture, Rocasolano expressed his admiration for Einstein and for the research being carried out in Zaragoza based on Einstein’s work. Lorenzo Pardo, secretary of the Zaragoza Academy of Exact Sciences, then awarded him the title of corresponding member. For the diploma, see Abs. 544. In the evening, a dinner was held in Einstein’s honor at the German consulate. On 13 March, Einstein had originally planned to give his second lecture in Zaragoza at 11:30 A.M. He then planned to travel to Bilbao to lecture at the Society for Basque Studies. However, the lecture in Bilbao was canceled, and the second Zaragoza lecture was rescheduled for 6 P.M. In the morning of 13 March, Einstein therefore had time to tour Zaragoza. He visited the Basilica-Cathedral of our Lady of the Pillar, the La Seo Cathedral, the Lonja, the medieval commercial exchange, and the Al- jafería Palace in the morning. Lunch was held at 1 P.M. at the Centro Mercantile to which a distin- guished group of university professors was invited by the Academy of Sciences. The philologist Domingo Miral hosted the event and gave a brief speech in which he praised Einstein. In his reply, Einstein remarked that “up to the present moment, he had perceived the throb of the Spanish soul only in Zaragoza” (“hasta el momento actual, solo en Zaragoza había percibido las palpitaciones del alma
