author
A Dutch writer and humanitarian remembered both for his books and for efforts to help Jewish emigrants in Vienna before the Second World War, he had an unusually wide life that reached from literature into urgent public action.

Frank van Gheel-Gildemeester was a Dutch author whose name is now most often linked with the Gildemeester emigrants' aid action in Vienna in 1938. Sources available here identify him as a philanthropist of Dutch nationality who founded an organization in Vienna to assist migrants, and Project Gutenberg also lists him as an author with works in its catalog.
That mix of literary and humanitarian work makes him a distinctive historical figure. Rather than being known only for novels or essays, he appears in the record as someone whose writing career sat alongside practical efforts to help people facing displacement.
