Clearly the most famous person born in Chomutov, Franz Josef Gerstner (1756–1832) was a mathematician, physicist, astronomer, engineer and designer. He was the founder and first director of the Polytechnic in Prague (now CTU). One of his most famous achievements was his plan for a horse-drawn carriage route from České Budějovice to Linz. He was awarded a knighthood in 1810 in recognition of his work.
After his death Gerstner was buried in Mladějov near Jičín, but in 1932 the town of Chomutov had an honorary grave set up, into which part of his remains were moved.
