. Johann Heytz (Heitz), Berlin (1672 – 1737),
mark: Fleurs-de-lis/ I.HEYTZ /or crown/ I HEYTZ / stylised flower

Born in Herrenhof, Sachsen-Gotha, he was active as a wood turner and woodwind instrument maker in Berlin from 1700. From 1710 he was referred to in documents as ‘Royal Court and ornamental turner, also musical instrument maker’. Most of his instruments are covered with tortoiseshell and furnished richly with ivory rings. Kirnberger and Krickeberg presume that Heytz followed his apprenticeship France.
Through Pierre Naust the court in München acquired two of his recorders.
A relationship with French wood-wind-making seems obviously: Tortoiseshell work is a speciality of the south of France (Marseille).
Schmidt supposed that the instruments, marked with the ‘Fleurs-de-lis’, were produced for the French market. He is almost certainly right, which means that Heytz made recorders for the French Court.
Because of the close relations with the court in Berlin, we believe, that the court at Köthen obtained two of his recorders around 1720. This is the time when J.S. Bach was active there. The Brandenburg Concertos’ were written and Bach acquired a harpsichord from Mietke (Berlin) for the court in Köthen. It is certain, that the Brandenburg Concertos, except for the first one, were drafted for the chapel at Köthen and were performed in low pitch at a=400!
