In the biographical sketch about Rita Strohl (https://www.youtube.com/watch?v=PxGZZ2p1gQo) that I mentioned in another thread, the name Adrien Barthe is mentioned. Barthe gave her composition lessons every Sunday for six years. Barthe has not been mentioned here before. He left quite a substantial legacy, though, and may be of interest to some here. The Sibley Music Library has this finding aid (https://www.esm.rochester.edu/sibley/specialcollections/findingaids/barthe/).
One of the few pieces that can be heard online is the Passacaille for wind quintet, here (https://www.youtube.com/watch?v=2AjhE6iMLLQ) in the arrangement by Georges Waln.
