Stefi Kiesler and her husband, Frederick, met Katherine Dreier in 1926, when they introduced her to a number of European artists to be included in the International Exhibition in Brooklyn. The Kieslers became close, lifelong friends with Dreier and Marcel Duchamp and active contributors to the Société Anonyme. While employed at the New York Public Library in 1949, Stefi Kiesler served as the chief bibliographic researcher for the 1950 catalogue of the Société Anonyme Collection at Yale University. Dreier enthusiastically described Kiesler’s Typo-Plastic, mechanically produced works embodying the nonobjective style of the de Stijl movement, as expressions of “how the spirit dominates the hand and mind.”
