His parents were count Józef Wielhorski and Salomea Dembińska (daughter of Wolbromska).
When young Frédéric Chopin visited Rusinów, Józef swooned by listening to him playing piano.
According to Polish musician Jan Kleczyński, his own compositions, though being mostly bagatelles, valses and mazurkas,[2] bear little reminiscences to those of Chopin.
Kleczyński explained such a failure through their relative difficulty: Wielhorski asks for much larger hands than was typical in salon music.
His friend, the composer Aleksander Zarzycki performed some pieces by Wielhorski in concerts.
