The lecture will present recent additions to the newly discovered correspondence of Antonín Dvořák in the collection of the National Museum — Antonín Dvořák Museum. The museum’s current collection of the composer’s correspondence includes over 3,100 items, but new unknown letters are constantly appearing on the market, adding to the picture of the composer’s contacts at home and abroad. Dvořák corresponded with important publishers, conductors, and performers, but he also maintained private and family correspondence. The lecture will focus on Dvořák’s unpublished letters, which have been acquired in recent years for the collection of the Antonín Dvořák Museum. Attention will also be paid to the entire museum’s collection of the composer’s correspondence, its content, the current state of its processing, and its accessibility to the public.
