A Dictionary of Music and Musicians/Weyrauch, August von
WEYRAUCH, August Heinrich von. A composer whose name must be mentioned because he is the author of a song 'Adieu,' or 'Lebe wohl,' often attributed to Schubert, and at one time very much sung. It was published by the author in 1824, under his own name, with the title of 'Nach Osten,' to words by Wetzel. Its attribution to Schubert is due to Paris, where it was published about 1840 as 'Adieu! Paroles françaises de M. Bélanger,' etc. A transcription of it as Schubert's by Döhler (op. 45, no. 3), appeared in Germany in 1843, and lastly it was published in Schubert's name by Schlesinger of Berlin as a song with German text, in 1845. Weyrauch is not mentioned in any Dictionary, nor even in Whistling's 'Handbuch,' and the above information is taken from Nottebohm's Thematic Catalogue of Schubert, p. 254.
Whistling (1828) mentions a Sophie von Weyrauch as the composer of an Overture (op. 3), and two books of Dances for PF.
