Hochstetter published an article in "Musikalisches Wochenblatt" in Leipzig on 24 Jan 1901 giving a positive critique of a concert given in Budapest by Count Géza Zichy of Hungary who suffered a riding accident in his teens and lost his right arm.
Hochstetter also corresponded with Josef Rheinberger, a notable composer, organist and pianist from Vaduz, Liechtenstein who composed "Piano studies for one hand and for two hands, Op.113".
