Square Piano attr Caspar Katholnik (Katholnig)

This unsigned piano is attributed to the Viennese maker Caspar Kaholnik because of its similarities to an instrument by that maker located in the Hungarian National Museum in Budapest. Katholnik was born in Villach (Beljak), Carinthia, Austria, and moved to Vienna where he received a license to make instruments in 1801, becoming a citizen of the city a year later. In addition to square pianos, he advertised upright pianos, but none is known to survive.  Credit: Met Museum
