Johann Andreas Segner ( _hu. Segner János András; _sk. Ján Andrej Segner; 9 October 1704 – 5 October 1777) was a Carpatho-German mathematician, physicist, and physician. The inventor of the Segner-wheel, Segner was also a professor of the universities of Jena, Göttingen and Halle.

In the 16th century, Segner's ancestors came from Styria to Pressburg (Bratislava) [ [http://www-groups.dcs.st-and.ac.uk/~history/Biographies/Segner.html Segner biography ] ] in the Kingdom of Hungary; by the 18th century it was a predominantly German town. He studied at Pressburg, Győr and Debrecen. In 1725 Segner began studying at the University of Jena. In 1729 he received a medical certificate and returned to Pressburg, where he started to work as a physician, as well as in Debrecen. In 1732 he returned to Jena for his master's degree. In 1735 Segner became the first professor of mathematics, a position created for him, at the University of Göttingen. In 1755 he became a professor at Halle, where he established an observatory.

One of the best-known scientists of his age, Segner was a member of the academies of Berlin, London, and Saint Petersburg.

Segner was the first mathematician to demonstrate the sign convention of Descartes. The asteroid 28878 Segner was named after him.
