Szebellédy was born in
Rétság
Rétság is a small town in Nógrád county, in Hungary.
Location
Rétság is located north of Budapest on the E77 European main road, halfway between Vác and Balassagyarmat. The town is seated at the border of Cserhát and Börzsöny hills. ...

(1863–1939). In 1933 he became an assistant professor. He went to Zurich, Dresden and Leipzig, working at the laboratories of W. D. Treadwell,
Max Le Blanc (1865-1943) and Wilhelm Böttger (1871–1949). In 1935-36 he taught chemical analysis and worked on microanalysis techniques involving dyes, fluorescence, indicators and catalysts. He developed coulombetric (or coulometric) titration analysis along with Zoltan Somogyi (1915–1945) in 1938 where the volume of a chemical could be calculated using
Faraday's laws. He died at the age of 43, publishing more than a hundred papers.
