On August 24, 1983 Donner suffered a stroke, which he wrote happened "just in time, because when you are 56 you do not play chess as well as you did when you were 26". After surviving the stroke, he went to live in Vreugdehof, which he described as "a kind of nursing-home". He was unable to walk, but had learned to type with one finger, and wrote for NRC Handelsblad and Schaaknieuws.The character Onno Quist in the novel (and film) The Discovery of Heaven by Harry Mulisch is based on Donner.
