Franz Josef von Gerstner (from 1810 Franz Josef Ritter von Gerstner; ; 23 February 1756 â 25 July 1832) was a Czech-German physicist, astronomer and engineer.
Gerstner was born in Chomutov in Bohemia then part of the Habsburg monarchy (now in the Czech Republic). He was the son of Florian Gerstner (1730âÂÂ1783) and Maria Elisabeth, born Englert. He studied at the Jesuits gymnasium in Chomutov. After that he studied mathematics and astronomy at the Faculty of Arts at the Charles-Ferdinand University in Prague between 1772 and 1777. In 1781, he started to study medicine at the University of Vienna, but later decided to quit his studies. Instead, he worked as an assistant at the astronomical observatory in Vienna under supervision of Maximilian Hell. In 1784 he returned to Prague, where he got a position at the Clementinum astronomical observatory in Prague. In 1789, he became professor of higher mathematics, mechanics and hydraulics at the university in Prague.
In 1792, Gerstner married Gabriele von Mayersbach (died 1808). They had nine children including Franz Anton von Gerstner (1796âÂÂ1840).
In 1795, Gerstner became a member of the government commission which tried to improve higher technical education in the Habsburg monarchy. Following his suggestion, the old engineering school in Prague () was converted by the decree of Emperor Joseph I to a polytechnic school in 1803. The new Polytechnic Institute in Prague was officially opened on 10 November 1806, and Gerstner became its first director. In 1811, he was appointed by the Emperor to the position of the Director of hydraulic engineering in Bohemia.
In 1823, due to an illness, he was forced to stop his classes at the university. Gerstner died and was buried in MladÃÂjov, Bohemia, in 1832.
From his works the most influential was Handbook of mechanics (). This fundamental text-book was published in three volumes (1831, 1832 and 1834), with more than 1400 subscribers.
In 1804, Gerstner published a pioneering work Theory of water waves. The so-called Gerstner wave is the trochoidal wave solution for periodic water waves â the first correct and nonlinear theory of water waves in deep water, appearing even before the first correct linearised theory.
His work focused on applied mechanics, hydrodynamics and river transportation. He helped to build the first iron works and first steam engine in Bohemia.
In 1807, he proposed the construction of a horse-drawn railway between the Austrian Empire towns of ÃÂeské BudÃÂjovice and Linz, one of the first railways on the European continent. The construction of this railway was started in summer 1825 by his son Franz Anton von Gerstner. The regular transport between ÃÂeské BudÃÂjovice and Linz started on 1 August 1832.
Between 1802 and 1803, Gerstner served as a chairman of the Royal Bohemian Society of Sciences.
In 1808, he received the Imperial Order of Leopold. In 1810, Gerstner was elevated to the nobility as Ritter von Gerstner.
The polytechnic school founded by Gerstner exists till today as the Czech Technical University in Prague (ÃÂVUT).
The institute for artificial intelligence and cybernetics research at ÃÂVUT bears the name Gerstner Laboratory.
