He seems to be the typical one-piece-composer. If you have heard of him at all then you have heard the Horn Concerto in A Minor in a recording by Zbigniew Zuk.

This is the only 'substantial' source of information I found by googling.
Does any of you know more about him, perhaps even heard other works?
It's tantalising to read that he composed 'a wide range of works including songs, cantatas, organ pieces, and a violin concerto.'
hrm. as I gather it says in notes to that recording or in other writings by the soloist (which VIAF is using as source), Swiss composer of Corsican descent, born 1893, died 1977. Also wrote a Nativity Cantata.
