Career
During World World War II he embarked on a spying mission in Germany for the Front de l"Indépendance Belgian communist resistance organization, bringing back the first reliable information about the fate of Jews deported to Germany, as well as detailed information about the functioning of the Auschwitz concentration camp. Martin, who possessed a doctorate, had travelled in Switzerland, France and Germany before the war, and his title had given him access to a network of good contacts in German universities. Martin"s proposal was accepted, but the mission was different from what he had imagined.
At the request of the official of the Comité de Défense des Juifs, he was ordered to observe directly where the trains went which carried the deported Jews of Belgium.
He manufactured a project researching the psychology of different social classes as cover. The project was accepted by the occupier and he obtained permits to travel between Frankfurt, Berlin and Breslau during the period of 4–20 February 1943.
At Katowice, not far from Auschwitz, Martin met workers from the Service du Travail Obligatoire in a bistro, who described to him the mass extermination of Jews and the incineration of their bodies. He met them again on several occasions.
Betrayed to the Gestapo, he was arrested and imprisoned on 1 April 1943 at the Radwitz camp, where he served as an interpreter.
He escaped on 15 May of the same year. After secretly returning to Belgium, he wrote a report to his resistance comrades in the Front de l"Indépendance who passed the results of his investigations on to London. Martin himself went underground in the Charleroi area.
He was arrested by the Gestapo, and transferred to Kamp Vught in the Netherlands.
He escaped yet again, and was sheltered by his resistance comrades. After the war, Martin worked overseas for the International Labour Organisation.
He died in complete anonymity in 1989.
