Alfred Wotquenne (French: [wɔtkɛn]; 25 January 1867 – 25 September 1939) was a Belgian musical bibliographer, best known for his catalogues of the works of Carl Philipp Emanuel Bach and Christoph Willibald Gluck.
He studied at Brussels' Conservatoire Royal, where his teachers included Louis Brassin (piano), Alphonse Mailly [fr] (organ), and François-Auguste Gevaert (theory).
The best known of Wotquenne's achievements is his 1905 bibliographical study of Carl Philipp Emanuel Bach, but he also performed similar services for other composers: Baldassare Galuppi (1900), Christoph Willibald Gluck (1905), and Luigi Rossi (1909).
[3][better source needed] By royal decree he lost the Order of Leopold and his position as chief librarian on 9 August 1919.
From 1921 Wotquenne lived in France, working in Antibes as a choir master and organ teacher.
