Biography
Robert Durrer was born in 1890 in Arbon, a town on the southern shore of Lake Constance in Thurgau, Switzerland. He studied engineering and metallurgy at RWTH Aachen University, a top European technical school, where he gained a strong foundation in iron and steel production. His education at Aachen deeply influenced his career path in the German-speaking world of industrial research.
Durrer worked in the steel industry during a time of major industrial growth and political change. He was involved in the German steel sector, including during the Nazi years, focusing on improving how iron was turned into steel. His most significant achievement came in 1948 when he successfully introduced the basic oxygen steelmaking process. This method used a high-purity oxygen jet on molten pig iron to remove impurities faster and more efficiently than the old Bessemer or open-hearth methods, marking a major change in the global steel industry.
The technology Durrer developed was improved and adapted in Austria. A group led by Dr. Theodor Eduard Suess took the process to an industrial scale, after which Austrian firms VÖEST and ÖAMG in Linz and Donawitz commercialized it. Known internationally as the Linz-Donawitz process or the LD process, it became the main method for steel production worldwide. Although named after the Austrian towns where it was scaled, Durrer's initial work was key to its success.
Besides his industrial research, Durrer was dedicated to teaching. He held a university position and helped train future metallurgists and engineers. He authored Die Metallurgie des Eisens, a comprehensive work on iron metallurgy that showed his expertise in both theory and practice. This publication made him a leading figure in the field and remained a go-to reference for experts. In honor of his work, he received the Bessemer Gold Medal, a top award in steel and metallurgy, along with an honorary doctorate and the title of Ehrensenator. Robert Durrer passed away in 1978 in Zumikon, near Zurich, Switzerland.
Before Fame
Robert Durrer was born in 1890 in Arbon, a small industrial town in northeastern Switzerland known for its mechanical and manufacturing background. Growing up in the late nineteenth and early twentieth centuries, he entered an era when steel was crucial to modern life, essential for railways, bridges, shipbuilding, and the machinery of war and commerce. There was a strong demand for more efficient and cost-effective steel production methods, providing young engineers skilled in materials science with plenty of chances and motivation to enter the field.
He chose to study at RWTH Aachen University, placing himself in the hub of technical culture in German-speaking Europe. This environment prioritized metallurgical research and fostered strong ties between industry and academia. His education at Aachen gave Durrer both the theoretical knowledge and the hands-on experience that defined his career. After leaving Aachen, he moved into industrial metallurgy, gradually building up expertise and reputation in the German steel sector. His breakthrough experimental work in the late 1940s gained him international notice.

Did You Know?
- 01.The steel process Durrer invented is named not after him but after the Austrian towns of Linz and Donawitz, where it was first brought to commercial industrial scale.
- 02.Durrer successfully tested the basic oxygen steelmaking process in 1948, just three years after the end of World War II, a period when European heavy industry was rebuilding under constrained conditions.
- 03.The Linz-Donawitz process that grew from Durrer's work eventually displaced older methods and today accounts for the majority of steel produced globally.
- 04.Durrer authored Die Metallurgie des Eisens, a major technical reference work on iron metallurgy, demonstrating that his contributions extended from hands-on experimentation to systematic scientific writing.
- 05.He held the distinction of Ehrensenator, an honorary senatorial title awarded by universities in German-speaking countries to individuals who have rendered exceptional service to academic or scientific life.
