German-American textile designer Anni Albers (who was married to Josef Albers) worked with Knoll from 1957 into the 1970s. Her Rail textile was introduced in 1962. "Albers had experimented with weaving gauze since the 1920s," Makovsky says. "Here she twisted threads so that it has these wide opens spaces in the textile itself. In the 1950s she wrote about using loose and rigid textiles as space dividers, which Florence Knoll had begun doing in showrooms. Florence wanted you to use textiles in very architectural ways, not always as drapes or upholstery but as different textures and as dividers in a space."
