There, too, he found two terms: one caused by the interference of waves and one due to independent light quanta. [42]In 1963, De Broglie recounted that Einstein had obtained a copy of his dissertation (De Broglie 1924) in the summer of 1924 through Paul Langevin, who had asked De Broglie for a copy and sent it to Einstein (see Interview with Louis de Broglie, 7 January 1963, Niels Bohr Library, American Institute of Physics). [43]A detailed discussion of this paper is given in Pérez and Sauer 2010. [44]See Ehrenfest 1911, Ehrenfest and Kamerlingh Onnes 1915, and De Broglie 1922.

[49]The initiative was nevertheless adopted by the University of Buenos Aires which, in October 1922, decided in principle to invite Einstein to lecture at the university. However, this was not fol- lowed up with an actual invitation at the time. See Ortiz 1995, p. 81.
