William de Gelsey

[7][8] His maternal great-grandfather, Krausz Mayer (1809–1894),[9] was a landowner and distiller, who had been granted nobility and the noble predicate of megyeri by the King on 3 September 1882.

After studying at the Royal Catholic University High School in Budapest, he followed in his father's footsteps to obtain an MA in Natural Sciences from Trinity College, Cambridge.

After gaining experience at Imperial Chemical Industries (ICI), he turned to management consulting when it became apparent that as a Hungarian he had little chance of becoming head of the international division.

[12] Together with his brother Alexander de Gelsey,[13] they played an instrumental role in returning the more than 300-year-old Royal University Catholic High School (which was closed in 1948) to its original building.

William de Gelsey personally secured the application for the 'EEA and Norwegian Financial Mechanisms' tender as well as co-financed 15% of the project (€150,000).
