Edward Wormley (1907-1995) is often cited as a top designer of American modernist furniture. Starting at the Dunbar Furniture Company at age 23, Wormley eventually became its sole designer and retained a partnership with Dunbar for over thirty years. Wormley taught at Parsons School of Design between 1952 and 1970. The collection includes photographs, slides, subject files, clippings, technical drawings, catalogs, and sketches.

In 1979, Harold Matossian (Parsons School of Design, 1968) became director of the Knoll furniture company's graphics department, producing invitations, brochures, stationery, catalogs and other corporate literature for the company until 1994. The Kellen Design Archives holds finished examples of these graphics.
