Three generations of the Dohy/Göllner family contributed to the training of hundreds of agricultural engineers, all three of whom had ties to Debrecen, Eastern Hungary. Today, Wikipedia articles also preserve their memory and activities.

- (Senior) János Göllner (1871–1942), a mechanical engineer, fled with his family from Kolozsvár to Debrecen after the Treaty of Trianon (1920), where he headed the technical department of the Agricultural Academy.

- János Dohy (earlier Göllner) (1905–1990) learned at the secondary schools from the Piarists in Debrecen, then graduated as an agricultural engineer from the Debrecen-Pallag Academy of Agriculture in 1926 (phytopathologist).

- János Dohy (Junior) (1934–2002) agricultural engineer, university professor, and researcher of animal breeding and husbandry were related to his activity. He was a member of the Hungarian Academy of Sciences (HAS)
