The Rotismühle (also Rotis-Mühle , E-Werk Aicher ) is a former castle mill in Rotis , a hamlet in the district of the large district town of Leutkirch in the Allgäu in the Ravensburg district , in Baden-Württemberg, which was first mentioned in a document in 1414 .
description
The Rotismühle was a grinding mill and sawmill operated by four water wheels until the 1920s . The then Rotismüller Anton Bertele installed two Francis turbines in 1924/25 instead of the water wheels that were conventional at the time . Between 300 and 800 seconds in the top of the liters of water Hofser Ach flow through the 150-meter engine channel in the power house of the Rotismühle. As early as the thirties of the last century, the electricity generated was also used for the miller's family's own consumption. Until 1994, however, the hydropower plant generated electricity for its own consumption as an island system . A general public power grid as we know it today did not exist back then. The next private network entrepreneur was the "Suiter Company" from Lautrach , which extended its network to the Rotis until the 1960s. This was then taken over by Lechwerke . In 1950 one of the Francis turbines was replaced by an Ossberger or cross- flow turbine . These turbines were also used in Schmidsfelden and the Emmerlander Mühle. The grinding operation of the Rotismühle was deregistered from the Bundesmühlenkontor in 1960, and the sawmill was shut down ten years later in 1970.

In 1971 the writer and member of the peace movement Inge Aicher-Scholl and the designer and co-founder of the Ulm School of Design, Otl Aicher, acquired the property. The “büro aicher” moved into the premises of the mill and the sawmill. Aicher, one of the pioneers of corporate design, called the font he developed "Rotis". From the “büro aicher” the “rotis office” later even became the “autonomous republic of rotis”. The hydroelectric power station was preserved. At the power house of the mill, Aicher had the brick north wall replaced by a glass wall with a metal frame in 1982 according to his plans. Instead of the sawmill, a residential building measuring 20 by 10 meters was built. The building with a gable roof and the return is in the left part of the house, the former grinding mill and on the right the miller's living quarters. From 1984 to 1991 the Rotis Institute for Analog Studies was located on the Rotismühle site, an international center for the design and visual representation of companies and institutions. After Otl Aicher's death, the second youngest son, Julian Aicher, took over the water mill in 2000. Already in the last decades of the last century, complex renovation work was carried out on the hydropower plant, especially in the area of the river, weirs, engine canals and turbines. This was also necessary because several heavy rain events in 2010, 2015 and 2016 led to major damage to the river structures, and in some cases electricity production came to a standstill for months or was severely impaired. Of the nine documented waterworks along the Hofser Ach during the wedding, seven were still in operation in 2015.
