Born in
Silesia, Treutmann learned his trade from the Herbst family of organ builders in Magdeburg,
Duchy of Magdeburg. His teacher was
Heinrich Herbst the Younger, the son of
Heinrich Herbst the Elder. Herbst (the Younger) later built the cathedral organ in
Halberstadt between 1714 and 1718. Since Treutmann's works show stylistic similarities to the organs of the Hamburg organ builder
Arp Schnitger, it is assumed that Treutmann worked at least temporarily with the latter as a journeyman and possibly also participated in the construction of the "Arp Schnitger organ" (1689 to 1694) in the
St.-Johannis-Kirche in
Magdeburg. In 1695, Treutmann became self-employed and founded his own workshop around 1700. His first independent work is known to be the repair of the
Brunswick Cathedral in 1700. After that, the repair of an organ built by
Gottfried Fritzsche in 1637 in the
Dreieinigkeitskirche in
Allermöhe near Hamburg is attested. Further works are known from the year 1713 in the Magdeburg area. Between 1721 and 1723 Treutmann built the organs of the churches of St. Marien and St. Nikolai in
Gardelegen; subsequently he extended the organ of the in
Harbke near Helmstedt, also a work by Gottfried Fritzsche from 1621/22. In 1732, he worked again in Magdeburg and built an organ for the French Reformed congregation there. The
Kloster Grauhof near Goslar commissioned Treutmann in 1734 to build an organ with a total of 42 stops and 2500 pipes. It was completed in 1737 and is considered his most important work; it was restored from 1989 to 1992. In 1741, Treutmann was again commissioned to repair an organ by Arp Schnitger in the
St.-Jacobi-Kirche and reworked another of Schnitger's works in the
St.-Johannis-Kirche in Magdeburg between 1747 and 1750. Treutmann died in
Magdeburg. == Work (selection) ==
