Louis de Broglie (1892-1987)
Louis de Broglie is one of the speakers of the 1927 Conference. He takes part in the 1933 Conference, is invited to take part in the 1939 Conference (which never takes place) and is represented at the 1948 Conference by Marie-Antoinette Tonnelat.
Louis de Broglie wishes to attend the 1924 Conference as a listener, a request that is turned down given the strictly confidential nature of the Conferences on Physics. However, he will take part in the 1927 Conference, presenting his ‘pilot-wave theory’.
