ABSTRACT
The first buildings to be occupied after the liberation of Brussels in September 1944 was 453 avenues Louise, the local Gestapo headquarters which was found to contain a large archive documenting the German counterespionage activities throughout the Nazi occupation. Of particular interest was a group of files, later known as the Robinson Papers, which had been generated during a lengthy investigation of a Soviet network that had been rounded up in December 1942, and had been headed by Henri Baumann, alias Henri Robinson, a KPD youth member and a leader of the Comintern's youth movement. There the matter had ended, except that according to the Robinson Papers, which were misplaced and not properly studied until 1947, both Frederick Meredith and the Wilfred Vernon were Soviet spies who had been haemorrhaging aviation secrets to their controller, Ernest D. Weiss, since at least 1936.
