Johann Friedrich Heintzmann (born August 24, 1716 in Clausthal , † July 11, 1764 in Hattingen ) was a master builder from Wernigerode , who was assigned an important role as a miner in the reform of the Ruhr mining industry .

In February 1755, the Prussian King Friedrich II sent the Privy Finance Councilor Ludwig Philipp Freiherr vom Hagen to the County of Mark to investigate the conditions in the Brandenburg coal mining and the possibilities there to increase state revenues. Vom Hagen commissioned the miner Heintzmann from Wernigerode with the elaboration of new mining regulations and the miners' union regulations. His appointment to the mountain ridge in County Mark took place on March 30, 1756.

On April 29, 1766, Frederick II issued the "Revised Mining Regulations for the Duchy of Cleve, the Principality of Meurs and the County of Mark" in order to direct mining in a mercantilist manner. The ordinance was finally supplemented by a "general privilege" for miners in Kleve , Moers and Mark from May 16, 1767. These provisions regulate the development of mineral resources, the supervision by the mining authority of salaries, coal prices and working hours as well as jurisdiction over the miners, as well as the establishment of miners' funds in the event of illness of the miners.

On April 28, 1744 he married Dorothea Magdalena Mühlhahn from Clausthal. The sons Julius Philipp Heintzmann , royal Prussian Bergrat, and Heinrich Christian Heintzmann , royal Prussian Ruhrschifffahrt director, emerged from this marriage.
