Once settled in Paris, she quickly became a popular
socialite due to her association with novelist, painter, and poet
Laurence Vail. In 1923, she became reacquainted with Marchel Duchamp through her relations to the Paris Social scene. They began to form a relationship. Duchamp, however, was not faithful and pursued relations with other women during this time. Though they never married, from 1927 the two lived in close relation – living together, vacationing together, and being seen in public together. In 1929, Reynolds took up
bookbinding at the Atelier of master French binder Pierre Legrain. Legrain's style of binding was notably modernist in contrast to the prior tradition of French book binding which was more deferential to a classical style. Legrain's influence, as well as that of Duchamp, led Reynolds to adopt a relatively avant-garde style of book binding, influenced by French Surrealism. She produced many bindings herself, as well as a few in collaboration with Duchamp, such as their collaboration on a binding for
Alfred Jarry’s
Ubu Roi. During 1930s, her relationship stabilized with Duchamp. During this time she actively worked as a bookbinder and continued to collaborate with Duchamp. Though she did not share a working studio with Duchamp, their mutual house was considered itself an extravagant aesthetic affair and frequently hosted the literati and artists of the time. This lasted until the Nazi occupation of Paris, which made it difficult for their relationship. Duchamp left for the unoccupied parts of France, urging Reynolds to join him. Duchamp eventually left for New York in 1942. During the early 1940s, Reynolds played an active role in The French Resistance. She also provided financial support for a variety of friends throughout the occupation. Notably, she helped the artist
Jean Hélion hide from the Nazis after he escaped from a German prisoners camp in 1942. By late 1942, she became aware that she was under
Gestapo surveillance and planned to leave occupied Paris. She escaped into Spain by crossing the Pyrenees. After some difficulties, she arrived in Madrid on December 14, 1942. On January 6, 1943, she returned to New York via aircraft. == Later life ==
