title: [Boltzmann's principle and Einstein's first quantum theories].
abstract: The crucial role played by statistical mechanics in Einstein's work on quantum theory has been repeatedly stressed. Nevertheless, in this paper we argue that Einstein's attitude to Boltzmann's principle was more complex than is usually understood. In fact, there are significant differences and nuances that in our opinion have yet to be sufficiently considered, in the various interpretations and uses Einstein made of this principle in his work on quantum theory, more specifically between 1905 and the First Solvay Conference, in 1911.
