At the end of the First World War Vincey, then a metal worker joined a group called "Jeunesses syndicalistes" . Through the individualist anarchist ideas then current, he later found himself in sympathy with what was becoming the :fr:Mouvement libertaire|Libertairan Movement. His robust intellect rapidly came to focus on the economic problems of the post-war years. The Anarcho communistGeorges Fontenis would later described Vincy's philosophy at this time as that of a "Stirnerian individualist". Directly after his death in 1960 Vincey was reported as having often described himself to Émile Armand as "an individualist adherent of the organisation founded on the responsibility of the free individual, within a group structure determined by collective agreement, to organise without any constraints the work he has accepted". He became aligned with the Anarchist Union and then, from 1936, with the Anarchist Federation of the French-speaking world. Following the German invasion of May/June 1940 he took part in clandestine meetings which enabled the anarchists of Paris to maintain contact. After the liberation Georges Vincey was one of those who re-established the French Anarchist Federation. Others included Robert Joulin, Henri Bouyé, :fr:Georges Fontenis|Georges Fontenis,, Renée Lamberet, Maurice Joyeux, and Paul Lapeyre, Maurice Fayolle, Maurice Laisant, Giliana Berneri, Solange Dumont, Roger Caron, Henri Oriol and Paul Chery. Between 25 and 27 December 1945 he took part in the founding congress of the French Anarchist Federation, applying the idea of Synthesis anarchism, and made up of excluded groups and former militants who had left the old fractured and more narrowly focused anarchist groupings in response to practices by those groupings deemed gratuitously authoritarian. Basic principals were drawn up for the new Federation to maximise the numbers while embracing a disparate range of anarchist views. This was challenging, as the instigator of the reconstituted Anarchist Federation, Maurice Joyeux found himself obliged to compromise with individualist anarchists such as Vincey. The outcome was an operational approach that Joyeux described as "impossible": requiring decisions to be unanimous had the effect of giving every member a power of veto over the Federation's direction. In October 1954 Georges Vincey was appointed administrator of the anarchist movement's collectively produced journal, the Monde libertaire. He would retain these responsibilities till forced out by his illness in May 1959.
