The story of the Salzburger Festspiele (Salzburg Festival) officially began on 22 August 1920 with a performance of "Jedermann" by Hugo von Hofmannsthal, staged by Max Reinhardt on the square of Salzburg Cathedral. The Café Tomaselli is said to have played a key role in its creation. In 1967, the magazine "Madame" wrote that Hermann Bahr, Hugo von Hofmannsthal and Max Reinhardt had come up with the idea for the festival at their regular table at the Tomaselli. Eminent figures such as Federal Chancellor Ignaz Seipel, governor Dr. Franz Rehrl, actor Hans Moser, opera singer Lilli Lehmann, festival conductor Bruno Walter and several members of the "Jedermann" ensemble such as Alexander Moissi and Helene Thimig also appeared in the Tomaselli guestbook from 1923 to 1928.
