In the 1920s Fergusson was settled in a studio in London. His first solo exhibition was in 1923 and he was also involved in several important group exhibitions. In 1928 he and his partner, the dancer Margaret Morris, moved to Paris, where they lived until the spectre of war once again loomed over Europe, prompting the couple to move to Glasgow in 1939 where they were to remain for the rest of their lives. A member of Glasgow Art Club, Fergusson exhibited a portrait in the club's exhibition, April 1939.
