In the beginning, he made giraffe pianos with bassoon and Janissary registers that quickly gained recognition.

[3] In the 1830s, together with his son Julian, he custom-built a piano with a silencer lift that was divided into a lower and upper register.

A frequent guest of the home art salon and a factory store was Frédéric Chopin, who bought Buchholtz's piano,[4] which was later burned during the January uprising.

[3] It was said that every time more than two guests came to hear Chopin play, the company was moved to the Buchholtz workshop.

From his marriage (1819) with Emilia Boratynski,[5] he had 15 children, including Julian, Alojzy (born 1822) and Matylda Dobrowolska (1825—1910).
