Company history
Sulzer was founded in Winterthur, Switzerland, in 1834 by brothers Johann Jakob and Salomon Sulzer with their father, initially as a foundry and workshop. The company built its first steam engine in 1854 and developed its first diesel engine with Rudolf Diesel in 1898. In 1914, the family business was reorganized into three joint-stock companies, including a holding company.[26][27][28]
Sulzer took over the Swiss Locomotive and Machine Works in 1961, then divested its diesel and railway businesses in 1997 and 1998 as it refocused its portfolio. It expanded into application systems with acquisitions in 2006, and acquired GTC Technology in 2019, adding licensed petrochemical process technology. In 2021, Applicator Systems was spun off as medmix.[29][28][30][31] [26][27][28][29][30][31]
