At FederWERK there are no invented themes.
At Hotel FederWERK in St. Georgen, each of the 51 rooms is dedicated to a real person, a company or a product that shaped the industrial and innovation history of the Black Forest. A large-format wall motif and the accompanying story make every room a chapter of its own – from a wooden-geared clock made in 1730 to today’s XR learning software.
The rooms tell of real people, companies and products from St. Georgen and the region: of clockmakers and tinkerers, of factory founders and families of inventors, of clock movements, gramophones, motors and machines.
The rooms are deliberately different, because the paths they tell of were never uniform either. Technology is not explained here; it works through design, objects and atmosphere. You do not need to know anything in order to sleep well. But you may well become curious.
By the way: the room categories recall the factory too. They are named after the stages of a company’s work – Development, Production and Sales.

How to discover your room story
Room 323
The wooden-geared clock from the early days
Andreas Müller (1684–1745) is considered the first clockmaker in St. Georgen. According to the 1859 chronicle by the pastor Eduard Christian Martini, he taught himself the craft „simply by watching and imitating“. His original wooden-geared clock of 1730 has wheels and shafts made of wood, a verge escapement with a balance beam and an alarm mechanism striking a glass bell.
Room 330
Serial number 1
In 1907 the brothers Christian and Josef Steidinger began manufacturing together. The gramophone drive with serial number 1 dates from that year: spring drive, hand winding by crank and a centrifugal governor for 78 revolutions per minute. A year later the drives caused a stir at the Leipzig spring fair – the beginning of a story that led to DUAL.
Room 125
The clock for carrier pigeons
A clock that measures flight times: the pigeon timing clock by Tobias Baeuerle & Söhne was started at the moment of release. At the destination the arrival times were stopped, the pigeons’ rings were locked into a rotating magazine and the time was printed on a paper strip. It was built in the company in whose factory building you are staying today.
Room 121
The anaesthesia stopwatch
Otto Rapp, who began his clockmaking apprenticeship at Tobias Baeuerle in 1912, designed an anaesthesia monitoring clock for the Dräger works in Lübeck in 1952. The anaesthetist counted 15 pulse beats or five breaths and read off pulse and respiration on the scale. Around 40,000 units were made over more than 40 years, with dials in nine languages.
Room 121
The anaesthesia stopwatch
Room 327 – The world’s first quartz alarm clock
In 1971 Staiger presented the CHROMETRON QUARTZ in St. Georgen – the world’s first battery-powered quartz alarm clock. A 1.5-volt battery and a quartz crystal running at 16.384 kilohertz provided precise one-second steps.
The anaesthesia stopwatch
Room 416 – Looking ahead
The line of innovation does not end in the past. In 2004 Martin Zimmermann founded the first virtual reality cluster in the Black Forest in St. Georgen; his company imsimity develops the XR learning software CyberClassroom, which makes the invisible visible and tangible in the classroom. Anyone staying here wakes up in the future.
The origin of time: Black Forest clocks & craft
c. 1680–1850 · craft, regionality, origin
At the beginning there are clockmakers in the side valleys of St. Georgen: farmers, craftsmen and traders who built the first Black Forest clocks out of wood, brass and a great deal of patience.
Andreas Müller (1684–1745)
Andreas Müller is considered the first clockmaker in St. Georgen. The pastor and chronicler Eduard Christian Martini wrote in 1859 that he had „probably acquired the craft simply by watching and imitating“. In the „Nest“, a small house in Brigach, he ran a workshop with his son and son-in-law. In 1725, together with Jerg Weißer, he repaired the tower clock of the Lorenzkirche, for 12 guilders plus food and drink.
- Room 323 – the original wooden-geared clock of 1730: a clock from the early days of Black Forest clockmaking. The wheels and shafts are made of wood, with a verge escapement with balance beam and an alarm mechanism striking a glass bell.
Philipp Haas (1802–1874)
Philipp Haas grew up in a family of clockmakers in the Stockwald, worked as a shepherd boy as a child and took over the clock trade in Bavarian Franconia at the age of 17. In 1831 he founded a clock trading company at the Gasthaus Hirsch. His sons turned it into Philipp Haas & Söhne, which from 1867 built metal clock movements on the „American principle“ – by their own account the first in Baden to do so. Around 1913 some 350 people worked there. In 1948 Hermann Papst moved into the company’s former buildings with his Papst motors.
- Room 110 – Black Forest clock of 1885: a wooden movement in „Schotten“ size with brass wheels, iron shafts and a quarter-hour striking mechanism.
Andreas Maier (1828–1900)
Andreas Maier, the son of poor parents, learned the painting of wooden clock dials and in 1852 founded the only factory of its kind in the Black Forest in St. Georgen. It worked with lithography. His descendants turned it into an internationally known maker of clock hands with the motto „Our hands, please note, are our strength“. It survives today as A. Maier Präzision.
- Room 220 – Black Forest clock of 1890: a nursery clock with a carved and painted dial. The cast weights are shaped like gnomes.
Mathias Bäuerle (1839–1916)
Mathias Bäuerle grew up in a clockmaking family in the Stockwald and founded his own clockmaking business in 1863. At first he made Schotten clocks with spring drives, later regulators. In 1888 he built a factory in St. Georgen and made a name for himself with precise movements and complex striking mechanisms. His brother Tobias founded the company in whose building FederWERK stands today.
- Room 221 – living-room clock of 1895: a fine wall clock for the Austro-Hungarian market, with a hardwood case, spring drive and a striking mechanism on a gong spring.
- Room 332 – the folding machine: after clocks and calculating machines, the company concentrated on folding machines from 1963. It still builds paper-processing machines today.
Mechanics & precision: precision engineering
c. 1850–today · accuracy, engineering thinking
Clockmaking becomes precision engineering. Counting, measuring, switching, clamping: anyone who can measure time can also control machines.
Tobias Baeuerle (1841–1914)
Tobias Baeuerle opened his own clockmaking workshop in Brigach in 1864 and in 1875 built a large factory and residential building on Bahnhofstraße in St. Georgen. From 1888 he made precise regulator pendulum clocks with cases from his own joinery. In 1903 his sons became partners and the company was renamed Tobias Baeuerle & Söhne. In 1964 it celebrated its centenary with 650 employees; its history ended in 1994. Hotel FederWERK now occupies its former factory building.
- Room 125 – clocks and technical movements: what made Tobias Baeuerle & Söhne great.
- Room 214 – meter for liquids: a measuring gear calibrated in „imperial gallons“, probably from the 1920s. It was presumably intended for fuel pumps or water meters and has an enamel dial.
- Room 225 – printing mechanism for recording devices: precision engineering for instruments that record measurements.
- Room 324 – high-precision signal clock: a clock with a signal generator for beacons on moored lightships near the coast, built for Pintsch Bamag in Berlin.
Tobias Bäuerle, son of Mathias (1869–1933)
To become less dependent on the fiercely competitive clockmaking trade, in 1903 Tobias Bäuerle began building mechanical calculating machines under the PEERLESS brand. In 1905 they were awarded a gold medal at the World Exhibition in Liège. Around 1904 the company was also making some 6,000 clocks a month.
- Room 116 – mechanical calculating machine, from 1913: a machine with a stepped drum and hand crank for all four basic arithmetic operations.
Christoph Jäckle (1894–1982)
Christoph Jäckle was the classic Black Forest tinkerer. He trained at Philipp Haas & Söhne and worked for more than four decades as a design engineer at Tobias Baeuerle on technical movements and measuring instruments. He also sat on the town council and led the Protestant brass ensemble in St. Georgen for decades.
- Room 120 – astronomical art clock of 1971: he put eight years and more than 5,000 working hours into this calendar clock. It shows sidereal time, moon phases, sunrise and moonrise and calculates the coming date of Easter every New Year’s Eve. He turned down offers: the clock was not for sale.
Dieter Grässlin (1926–1976)
Dieter Grässlin learned the clockmaking trade at Tobias Baeuerle, studied at the clockmaking school in Furtwangen and founded his own company in 1956. His time switches were patented worldwide.
- Room 012 – mechanical time switch of 1963: the world’s first time switch in the standard 72 × 72 mm housing size, modular in design for electrical installations and heating control.
- Room 222 – electronic digital time switch of 1980: the first of its kind with 127 switching commands.

Johann Friedrich Schlenker started out with a wood-turning workshop. His son and grandson turned it into a precision engineering business in Peterzell, now in its fourth generation.
- Room 212 – hydraulic clamping mandrel: a thin steel membrane expands under pressure and holds the workpiece, with a concentricity accuracy of under 0.005 millimetres.
Peter Sterman (b. 1959)
Peter Sterman started out in 2000 with a design office in the family cellar. In 2002 the company moved with eight employees into the renovated design offices of the old Baeuerle building – that is, into exactly the building in which you are staying today. Today it is a technology leader in bespoke clamping systems.
- Room 111 – clamping system for an eight-speed gearbox: it clamps a gearbox shift wheel firmly and still leaves the bore free of distortion. The tolerance is under 0.004 millimetres.
Ewald Granacher (1923–2016)
Ewald Granacher founded his precision engineering company in St. Georgen in 1968. Today it supplies highly complex parts for aerospace, motorsport and medical technology.
- Room 333 – clamping ring: a component made of bronze alloy with a fine thread, produced in very small batches to strict standards.

Friedrich Schunk founded a mechanical workshop in a garage in Lauffen am Neckar in 1945. Under his son Heinz-Dieter it became a world market leader in clamping technology and gripping systems.
- Room 210 – PGN-plus parallel gripper: since 2000 a dependable gripper for almost all handling tasks in production.
Sound & tone: the phono industry
c. 1900–1980 · emotion, culture, innovation
With the gramophone and the record player, technology became emotional. St. Georgen produced drives and turntables that reached millions of people.
Christian (1873–1937) and Josef Steidinger (1876–1925)
The Steidingers were clockmakers in the „Grumpenloch“, a side valley of the Stockwald. In 1907 the brothers founded Gebrüder Steidinger, and in 1908 they showed their gramophone drives at the Leipzig fair. In 1911 Josef set up on his own with Perpetuum, later Perpetuum-Ebner (PE). From 1935 all products made by the Steidinger brothers carried the name DUAL. By 1975 DUAL employed more than 3,500 people in eleven plants.

c. 1920–today · progress, efficiency, dynamism
The guiding figure of the house: no name appears at FederWERK as often as Papst.
Hermann Papst (1902–1981)
Hermann Papst is considered one of the most universally gifted German inventors of the 20th century: around 1,000 technical concepts, more than 200 German and some 400 foreign patents. He came to St. Georgen in 1928. In 1932 he patented the rotating-field motor with an external cage, the basis of the world-famous „Papst motor“. His engineering office became Papst Motoren KG in 1950. In 1979 he received the Federal Cross of Merit.
- Room 014 – fan electronics: Papst integrated the control electronics directly into the hub of brushless DC motors early on, for fans with variable speed control.

- Room 331 – Multidrive cassette mechanism: motors and control magnets sit in one compact drive block, with no gears to wear out, for hi-fi recorders.
Georg F. Papst (1935–2012)
After Papst Motoren was sold, Georg F. Papst founded PAPST LICENSING in 1992 and took over the historic patent portfolio. Licence partners included major manufacturers of hard disks and digital cameras. In 2002 the company moved to St. Georgen.
- Room 216 – hard disk: a magnetic storage drive. The platters spin in a dust-free clean room, driven by a brushless DC motor.
- Room 320 – 24-coil stepper motor: a synchronous motor that turns step by step with a controlled magnetic field.
Gerhard Sturm / ebm-papst
Gerhard Sturm (b. 1934) founded ebm with Heinz Ziehl in 1963. In 1992 it took over Papst Motoren in St. Georgen, and since 2003 the site has been called ebm-papst St. Georgen. With „GreenTech“ ebm-papst focuses on energy efficiency and sustainability and won the German Sustainability Award in 2013.
- Room 127 – ECI motor: a small electric motor that maintains oil pressure in automatic transmissions, in start-stop, hybrid or coasting operation.
Machines & production: industry as the foundation
c. 1850–today · stability, capability
Without machine tools there are no clocks and no motors. These companies built the machines with which the Black Forest produced.
Johann Georg Weisser (1840–1886)
Johann Georg Weisser built small lathes in his father’s forge and in 1856 founded the J. G. Weisser Söhne machine factory in St. Georgen, initially for the clock industry. By the end of the 1950s 420 people worked there. For its 160th anniversary in 2016 the company was given a new address: Johann-Georg-Weisser-Straße 1.
