28878 Segner           Discovered 2000 May 26 by P. Kušnirák at Ondřejov.
In 1750 Slovak physicist and physician Ján Andrej Segner (1704-1777) constructed a simple-reaction waterwheel known as Segner's wheel, an invention significant for the development of early reaction water turbines. He was a member of many scientific societies and professor at universities of Jena, Göttingen and Halle.
