The topic of the article is the correspondence of the pianist and composer Anna Teichmüller with Marta and Carl Hauptmann. The correspondence from the years 1900 – 1904 is in the collection of the Silesian Library in Katowice. As part of the legacy of Carl Hauptmann the correspondence was transferred to Katowice from the Storehouse of Secured Libraries after the war. On the basis of the preserved letters there was made an attempt to present the composer and the relations between her and the Hauptmann family (mainly Marta Hauptmann).
