I was interested to read the discussion on him. Coincidentally, his Mazurka Italienne for piano recently appeared on IMSLP. It is a really attractive salon piece, which I have recorded on my YouTube channel https://youtu.be/154V1cBOlng - although I doubt if it is representative of the sort of work he would have triumphed over Bartok with in the 1905 Rubinstein competition!
