Fryderyk Buchholtz
After he finished studying piano making in Vienna in 1815, Buchholtz came back to Warsaw and founded a piano factory at 1352 Mazowiecka street. One of his pianos was owned by Chopin's family. The composer was also a frequent guest of Bucholtz's home art salon and a factory store. Buchholtz died in 1837, but his wife and later their son Julian continued with the business. Only a small number of pianos made by Buchholtz factory survived until XXI century. In 2017 there was made a replica of a Buchholtz piano, which was later used in the first International Chopin Competition on Period Instruments in 2018.
