Founded in Warsaw in 1858 as an iron foundry by a shipbuilding magnate Andrzej Artur Zamoyski and led by Konstanty Rudzki, it soon expanded into machinery, steel and engineering.

[4] When the firm expanded into engineering, machinery construction and other areas, its name was changed and until 1932 it was "Towarzystwo Akcyjne Fabryki Machin i Odlewów "K. Rudzki i Ska"", which could roughly be translated as "'K.

[4] The official name was then changed to "Towarzystwo Przemysłu Metalowego "K. Rudzki i Spółka" SA" - "Metal Industry Company 'K.

In 1858, Konstanty Rudzki, a Polish engineer with experience in Western European steel and mining industries, was tasked by Count Zamoyski with creating a foundry in Warsaw.

[4] Zamoyski needed a specialised local firm to cooperate with his expanding shipbuilding business, so he financed the creation of the foundry, named K. Rudzki and Company.

[5] The second party was a partnership of Jakub Baird and Samuel Hirsz Mühlrad, both managers of steel and iron mills in the Old-Polish Industrial Region.

[4] At the 1876 Centennial Exposition in Philadelphia the "K. Rudzki i S-ka" company presented the Warszawianka, a revolutionary mechanical reaper, considered one of principal Polish inventions of the late 19th century.

[4][11][10] Eventually he retained 52 percent of shares, with the remainder in the hands of Alfred Czarnomski, Władysław Mazurowski and Józef Korycki.

In 1881 it obtained a patent for an innovative method of piping production, which allowed it to become one of principal contractors during the construction of Warsaw Waterworks and sewage system.

[4] Thanks to Konstanty Rudzki's innovative approach, his company became the only firm in the entire Russian Empire to be able to design a bridge, manufacture it, transport it to the construction site and build it in place, complete with caisson works and bridgeheads.

[4] They were then transported to the final destination either by rail or by ship (from the port of Odessa, through the Suez Canal to Nikolayevsk-on-Amur in the Far East, and then by river barges upstream), and then assembled by company's workers and engineers on site.

[3] The company was also one of principal contractors during the construction of St. Peter and St. Paul's Church in Warsaw (now St. Barbara's Church in Warsaw) (1894) and Hale Mirowskie (1899-1901),[4] it also continued to produce machinery for railway companies, overhead cranes, elevators, artillery, boilers, centrifugal pumps, water turbines and many other types of machinery.

[20] Despite attempts at entering the automobile production market through Ralf-Stetysz cars, in 1933 the Warsaw factory was closed down completely and only the Mińsk Mazowiecki plant remained operational.

[1] The difficult construction of the then-longest bridge in Poland was completed in under two years by K. Rudzki i S-ka and another company, Przedsiębiorstwo Robót Inżynieryjnych Leszek Muszyński.

[25] With time the POW camp was moved to another place nearby, while the factory started to increasingly rely on slave labour, notably from the Mińsk Mazowiecki Ghetto.

[20] Its production plant in Mińsk Mazowiecki was not damaged by the war,[25] but was nationalised and then taken over by a new, state-owned company producing steel elements for bridge construction, overhead cranes and similar machinery.
