[1][2][3][4][5][6][7] Jaszlinszky was born in September 1715 in Abaújszina (Kingdom of Hungary, modern-day Slovakia).
[11] Publication of Physica Generalis and Physica Particularis occurred in response to a 1753 order from Maria Theresa (Habsburg ruler in Vienna) requiring every professor to write textbooks instead of dictating lecture notes, which created a surge of works by Adanyi, Jaszlinszky, Reviczky, Radics, and Horvath.
[12][13] Jaszlinszky became rector of the university in 1771, and after the Suppression of the Society of Jesus in 1773, he became canon in Rozsnyó.
[14] He was a contemporary of Johann Baptiste Horvath, Leopold Biwald, and Joseph Redlhamer.
However, since Nagyszombat had an astronomical observatory (1755–1773), historians speculate that local Jesuit professors would have observed phenomena that would have convinced them that heliocentrism was correct.
