Heinrich Sulzer-Steiner (Winterthur, March 19, 1837 – Bern, May 11, 1906) came from a Protestant family in Winterthur. He is in the fourth generation of one of the most important Swiss foundries, founded in the 18th century.

Heinrich Sulzer joined Sulzer Brothers in 1860 and worked on the development of steam engines and in the field of heating. He managed the company from 1872 to 1906. Sulzer created the prototype of a diesel engine in 1897 and was a pioneer in developing this technology in the first half of the 20th century.

In 1883, he co-founded the Swiss Society of Machine Builders, where he served as vice president from 1883 to 1906. The Karlsruhe Polytechnic awarded him an honorary doctorate in 1903.

At the time of his death, in 1906, the company had more than 3 500 employees in Winterthur and some 1 000 in Ludwigshafen, near Mannheim, Germany.

In 2010, the Sulzer Group had a 3.18 billion Swiss francs turnover, with more than 160 subsidiaries and 13 740 employees worldwide.
