Pythagoras Mechanical Workshop Museum

Pythagoras Mechanical Workshop Museum is located in the premises of the earlier engine factory Pythagoras at the town of Norrtälje in the province of Uppland in Sweden. At the museum, production facilities and working conditions from the first half of the 20th century are on display. The factory produced hot bulb engines and spare parts for them from 1908 up to closure of the workshop in 1979. The engine factory is an industrial heritage site, complete with functioning production lines and offices. The company was founded in 1898 as Verkstads AB Pythagoras originally to produce mechanical calculators, hence its name from the Greek mathematician and philosopher Pythagoras. However, these plans failed and the factory instead started producing locks,

brass candlesticks and electrical fittings. Beginning in 1908 hot bulb engines were designed and manufactured, and such engines afterwards dominated the production line of the Pythagoras factory. Pythagoras manufactured hot bulb engines under the trademarks of Fram and Drott, the latter for export markets. The engines were used in farm machinery and on fishing and other vessels. The company was, with about 80 employees, once the largest manufacturer in Norrtalje.
