The foundry at Buckau, established by Hermann Gruson in 1855 at the mouth of the Elbe, transformed mechanical engineering in Germany by producing chilled cast iron wheels. These durable components became a standard requirement for railway manufacturers, signaling a shift in industrial production methods that utilized specific iron mixtures to enhance material strength.
Early Career and Technical Development
Born in 1821 in Magdeburg, Hermann August Jacques Gruson attended the Domgymnasium and the industrial and trade school. After volunteering in a pioneer unit, he studied at the University of Berlin. He gained initial industry experience at the engineering works of August Borsig and served the Berlin-Hamburg railway between 1843 and 1851. In 1854, he became the first technical director of the United Hamburg-Magdeburg Steamship Company before founding his own workshop in 1855.

Following a company strike in 1859, Gruson implemented a social wage policy to stabilize his workforce, ensuring no further strikes occurred under his leadership. He expanded production capacity significantly between 1869 and 1871 in Buckau. In 1870, he acquired the iron ore mine in Berggießhübel, which he named the Marie Louise Stolln, though he largely abandoned mining operations by 1892 due to disappointing yields.
Defense Contracts and Corporate Transition
Gruson secured Prussian military contracts after 1860, eventually developing armored gun turrets for coastal defenses, including projects at the Weser estuary and for the Italian navy in La Spezia. The company also produced the mobile fahrpanzer turret and maintained a 10-kilometer firing range in Tangerhütte. In 1886, the firm reorganized as a stock corporation, Grusonwerk AG Buckau, before Gruson retired in 1891. Krupp acquired the business in 1893.
Scientific Interests and Legacy
Beyond engineering, Gruson conducted botanical studies and amassed the largest collection of cacti in Europe. He authored a research paper on zodiacal light in 1893. Upon his death in 1895, he donated his plant collection and an endowment to Magdeburg, leading to the establishment of the Grusonschen greenhouses in 1896. He was a member of the Association of German Engineers and received the Grashof Commemorative Medal in 1894.
