[3] His first wife, Jean Humphry, ended her life on 29 March 1975, in the Cotswolds with her husband at her side, with an intentional overdose of medication; she was suffering from terminal bone cancer.

From 1993 Humphry was the president of the Euthanasia Research & Guidance Organization (ERGO), and chaired the advisory board of the Final Exit Network (formed 2004 to replace the Hemlock Society dissolved the previous year in mergers).

After four members of the organization were accused in Georgia of assisting a suicide,[7] he launched the Final Exit Liberty Fund which paid most of their legal costs.

In 2014, Humphry was given the Lifetime Achievement Award by the World Federation of Right To Die Societies for "contributing so much, so long and so courageously to our right to a peaceful death."
