Jan Tesánek

Jan Tesánek ( born December 9, 1728 in Brandys nad Labem, † June 22, 1788 in Prague) was Czech scholar and author of scientific literature.

Tesánek attended after high school, the University in Prague. In 1745 he joined the Order of the Jesuits and studied under Joseph Stepling mathematics, physics and astronomy. Stepling made ​​him acquainted with the works of Isaac Newton. After studying at the Faculty of Philosophy, he taught three years at the Latin schools, after which he began to study theology.

After his ordination he was appointed professor of the University of Prague. The Order sent him as a teacher of mathematics at the University of Olomouc, but through the intercession of Stepling he was two years later to return to Prague, where he was henceforth a professor of higher mathematics. Even after the dissolution of the Order in 1773 he was allowed to teach. 1778 appointed him to the rector of the mathematical- physical faculty.

His mathematical and physical knowledge earned him the nickname Czech Newton.
