How Paul Lévy saw Jean Ville and martingales.
We present the letters sent by Wolfgang Doeblin to Bohuslav Hostinský between 1936 and 1938. They concern some aspects of the general theory of Markov chains and the solutions of the Chapman-Kolmogorov equation that Doeblin was then establishing for his PhD thesis.
This paper concerns the emergence of modern mathematical statistics in France after the First World War. Emile Borel’s achievements are presented, and especially his creation of two institutions where mathematical statistics was developed: the , (ISUP) in 1922 and above all the (IHP) in 1928. At the IHP, a new journal was created in 1931. We discuss the first papers in that journal dealing with mathematical statistics.
