History of Louisenthal

Louisenthal, Gmund am Tegernsee (Bavaria)

Louisenthal’s history begins in 1818 with the founding of Jakob Deisenrieder’s watchmaker’s shop.
Mechanic Johann Mannhardt (born in Puerstling, Gmund) takes over the business together with merchant Niggl of Toelz, merchants Erich and Rueddorfer, and mechanic Drossbach.
Workshop is expanded and converted into a machine factory and hammer mill. The massive cast iron roof structure of the Walhalla building near Regensburg comes from this factory. A mechanical flax spinning mill is added. The tower clock in Louisenthal hails from this period. Owing to poor infrastructures, the company runs at a loss and is sold.
Stegmayer of Munich produces wire nails – widely known as  “Gmunder Stifte” – until 1859.
Coffeehouse owner Probst of Munich buys the buildings and sets up a Kneipp hydrotherapy institute.
The estate is put up for auction and purchased by the Schultes from Switzerland. Conversion to a cotton mill.
Schultes receives permission from King Max II to name the factory “Louisenthal”. The name “Louisenthal” (Louise Valley) refers to Duchess Ludovika (French: Louise), daughter of King Max I Joseph von Baiern, wife of Duke Max in Baiern and mother of Empress Elisabeth of Austria (Sissi).
The factory is sold to Carl Haug, co-owner of the paper mill Mueller am Baum.

Building of the pulp mill Muehltal.
Building of the canal bridge over the Mangfall and an electric power station. This is the site of the first electric power transmission in Germany.
Severe damage due to flooding of the Mangfall, causing the whole business to be closed down temporarily.
Building of the pulp mill Rainmuehle and installation of a second paper machine. Since the previous owners almost all failed due to the unfavorable transport conditions, Haug pushes for the construction of a local railway from Schaftlach to Gmund. After the opening of the railroad in 1883 transport by horse-drawn vehicles to Schaftlach becames unnecessary.
