Societé Naturelle company in
Antwerp. In January 1925, he married the Belgian national
Germaine Schneider Clais. The couple had a long honeymoon in Switzerland. In Switzerland, the couple were approached by the communist trade unionist
Léon Nicole. and recruited into the Comintern. They also met Swiss communist leader Cigy Bammater who introduced them to
Henry Robinson, a Soviet espionage agent who also worked for the Comintern. When they returned to Belgium two months later they initially settled in Liege before moving to Brussels in 1926. Upon his return Schneider found work with Natural Le Coultre, a Geneva based company specialising in the storage and transportation of fine art. Between 1925 and 1929, Schneider and his wife provided help to the
Communist Party of Belgium and offered their apartment as a safehouse for travellers who were members of the Comintern. As Schneider was working, he had limited participation in his wife's work during this period. In February 1929, the couple was deported from Belgium as communist agitators. His wife made a clandestine return to the country after a short period, while he managed to remain in Belgium. In the same year, Schneider began working for the British
Lever brothers company as a travelling soap salesman, eventually becoming department head. In 1930, he returned to Zurich for a year, before returning to Brussels. In March 1931, the expulsion order was rescinded, enabling the couple to stay in Belgium legally. Between 1929 and 1936, the couple lived a quiet live to avoid both party politics and all activities that involved the Comintern. ==Comintern==
