Thematic description and context:

Ján Andrej Segner (9. 10. 1704 Bratislava - 5. 10.1777 Halle, Nemecko) - fyzik, lekár, mimoriadny prof. na univerzite v Jene, prof. matematiky, fyziky a chémie na univerzite v Göttingene, prof. fyziky a matematiky v Halle. V roku 1750 zhotovil tzv. Segnerovo koleso - reakčnú turbínu, vynález, ktorý mal veľký význam pre vznik prvých vodných turbín, neskôr viedol ku konštrukciám reaktívnych vodných motorov. Segnerovo koleso bolo, napriek nízkej účinnosti, priemyselne využívané. J. A. Segner bol členom Petrohradskej a Berlínskej akadémie a londýnskej Kráľovskej spoločnosti.
