See Humboldtmühle, "In 1693 the mill and the estate were separated, Elector Friedrich III. bought the mill and auctioned it off. There were several changes of ownership, in 1776 it came back into the possession of the manor, at that time Alexander Georg von Humboldt. When in 1810 the mill obligation was abolished in Prussia and the freedom of trade introduced, the economic situation of the Tegeler Mühle deteriorated due to the competitive situation, although it was one of the largest of the eleven water mills in the Niederbarnim until then. The consequence were further changes of ownership. In 1834 the buildings burned down and were rebuilt in the same place by the owner Treskow.
A new economic foundation received the mill after the purchase by the mill Johann Gottfried Thiessen and his partner Karl Friedrich Henning 1847. It was in 1848 with a 20 PS strong steam engine to steam mill and obtained in 1851 with the deepening of the little river, a navigable link to Lake Tegel.
"Humboldt-Mühle" from 1887 onwards, the entrepreneurs Cohn & Rosenberg expanded the facility into a large mill, which they called the “Humboldt Mill”, from 1893 on in the legal form of the Humboldtmühlen AG . The cutting mill was probably abandoned around 1910. A major fire destroyed many of the buildings in 1912, so in 1913 the mill building, which is still preserved today, was built over the Tegeler Fließ along Schlossstrasse (today: An der Mühle ). The mill house, built in 1906, was equipped with a 100 hp steam engine that increased the daily milling capacity to 180 tonsincreased. The Humboldtmühle was one of the medium-sized mills in Berlin. There was now a siding to the Tegel freight station, which had to be abandoned in 1978/1980. From 1924, Victoria-Mühlenwerke took part in Humboldtmühlen-AG and incorporated them into their company in 1930. They operated the mill until it ceased operations in 1988."
