Viktor Kaplan Kaplan was born in Mürzzuschlag, Austria into a railroad worker's family. He graduated from high school in Vienna in 1895, after which he attended the Technical University of Vienna, where he studied civil engineering and specialised in diesel engines. From 1900 to 1901 he was drafted into military service in Pula. After working in Vienna with a specialisation in motors, he moved to the German Technical University in Brno to conduct research at the institute of civil engineering. He spent the next three decades of his life in Brno, and nearly all his inventions and research are connected with his professorship there (he became a full professor in 1918).

Viktor Kaplan and his turbine In 1912 he published his most notable work: the Kaplan turbine, a revolutionary water turbine that was especially fitted to produce electricity from large streams with only a moderate incline. From 1912 to 1913 he received four patents on these kinds of turbines. In 1913 he was appointed head of the institute for water turbines. In 1918 Kaplan turbines were first built by the Storek construction company for a textile manufacturer in Lower Austria. After the success of the first Kaplan turbines, they started being used worldwide and today remain one of the most widely used kinds of water turbines.

In 1926 and 1934 Kaplan received honorary doctorates. He died of a stroke in 1934 at Unterach am Attersee, Austria.
