Brongersma died in 1998 by means of voluntary euthanasia. His health failed and he grew lonely as his best friends died one by one. The social changes that had started in the 1980s, in response to the sexual revolution of the 1970s, caused him to become dispirited. Following his death, discussion flared up in the Netherlands as to whether people who were weary of life should be allowed to end their lives with the aid of a physician. Flip Sutorius, the doctor from Overveen who helped Brongersma in his chosen death, was prosecuted but not punished. The verdict was finally maintained in 2002 by the "Hoge Raad" (Dutch Supreme Court).
