Marie Nô Pin and Henri Julien were two artists who worked together under the pseudonym Seigle. For more than 50 years, they collaborated on significant pictorial work where it is impossible to distinguish the hand of one from the other.

Members to the Surrealist Group from 1940 to 1952, André Breton poetically, yet poignantly described their work as: “a hand as we have not yet seen, a man’s hand indistinguishable from a woman’s hand or, better, the hand; the hand of the woman and that of the man making only one by virtue of an agreement started for once so far that it involves the single intention and goes so far as to necessitate the pooling of the ‘expression.I think that we cannot insist enough on this exceptional representative of the art of Seigle in human value.”

Seigle enjoyed international recognition with exhibitions in France, the United States, Germany, Japan, and Switzerland. A tribute was paid to them by the Salon d'Automne in 1980, highlighting Seigle's significant impact on art history.
