The collection is comprised of Marty Spiegel's student work for Parsons' Environmental Design Department, which he attended from 1973 to 1976. Consists of course materials, correspondence, drawings and sketches, and printed materials, as well as digital reproductions of 35mm slides of Spiegel's work.

The Michael Kalil Oral History Project consists of audio interviews with colleagues, collaborators, and friends of interior designer Michael Kalil (1943-1991). Jean Gardner, Karyn Issa Ginsberg, and Marty Speigel discuss Kalil's education, career, and ideas with project archivist Jennifer Larson. Kalil's work—incorporating diverse principles of architecture and philosophy—was considered by many to be revolutionary in the 1970s and 1980s.

The oral histories comprising this collection were conducted in 2010 in preparation for the exhibit, Radical Shifts: Reshaping the Interior at Parsons, 1955-1985, to record perspectives on the interior and environmental design departments at Parsons School of Design in the 1960s and 1970s. During this period, Parsons' interior design program adopted a more experimental program of study in the newly-created Environmental Design Department.
