Aurel Stodola

Who is Aurel Stodola?

Aurel Stodola was a Slovak engineer, physicist, and inventor whose work laid the theoretical foundations of modern steam and gas turbine design. Born in Liptovský Mikuláš at the foot of the High Tatra mountains, the son of a leather manufacturer, he studied mechanical engineering at the Budapest Technical University, the University of Zurich, and the Swiss Federal Polytechnic, later renamed ETH Zurich, where he was appointed professor of mechanical engineering in 1892 and remained for more than four decades. His 1903 treatise Die Dampfturbine (The Steam Turbine) became the standard international reference on turbine thermodynamics, fluid flow, vibration, and stress analysis, going through several expanded editions and shaping turbine engineering across Europe and the United States for generations. In 1939 he led a pioneering test at the Brown Boveri company using a gas turbine to generate electricity, among the first demonstrations of its kind anywhere in the world. Among the many students who passed through his ETH Zurich lectures was a young Albert Einstein, who later credited Stodola's rigorous engineering courses as part of his scientific formation. In 1940 the Institution of Mechanical Engineers in Britain awarded him the James Watt International Medal for his contributions to turbine design. Stodola died in Zurich in 1942, and ETH Zurich continues to honor his legacy through the annual Aurel Stodola Lecture in mechanical and process engineering.
