| Abstract: | Nathaniel Kleitman, recognized as the father of modern sleep research, served on the faculty of the University of Chicago's Department of Physiology. His papers include notes, experiment data, drafts of articles and books, academic reprints, newspaper clippings, photographs, artifacts, and audio-visual recordings. |
The collection is open for research.
Series V contains audio and video recordings. Due to the lack of listening access copies for recordings, researchers will need to consult with staff before using audio and visual material.

Nathaniel Kleitman was born in Kishinev, Russia on April 26, 1895 to Jewish parents, Nathaniel and Pesia Kleitman. Nathaniel Kleitman, Sr. died of tuberculosis a few months prior to his son's birth. Pesia Kleitman remarried in 1900, and Nathaniel spent much of his childhood living with his maternal grandparents. He attended a private high school (a Realschule) until 1912. Kleitman studied briefly at Syrian Protestant College in Lebanon, now the American University of Beirut, in 1914. Following the outbreak of World War I, Kleitman and other foreign students were evacuated to Turkey. From there, Kleitman travelled to Greece, and then to New York in August of 1915. He became a naturalized U.S. citizen in 1918. The following year, he earned his B.S. degree from what is now City College of New York. In 1920 he received his M.A. from Columbia University, followed by two years as an instructor in physiology and pharmacology at the University of Georgia. In 1923 he became a research associate in physiology at the University of Chicago and earned his Ph.D. that same year. Upon graduation, Kleitman was the recipient of a National Research Council fellowship which allowed him to continue his research at the University of Utrecht, the University of Paris, and the University of Chicago until 1925.
He joined the faculty of the University of Chicago in 1925 as an assistant professor of physiology, and was named associate professor in 1929. He married Paulena Schweizer in 1927; they had two daughters, Hortense and Esther. Kleitman established the world's first sleep laboratory early in his career at the University of Chicago, and in 1939 published a seminal text on sleep research: Sleep and Wakefulness as Alternating Phases in the Cycle of Existence (revised and enlarged in 1963). Kleitman became a full professor at the University of Chicago in 1950.
Dr. Kleitman regularly used himself, family members, students, and assistants as research subjects. For several years, his daughters slept on beds designed to record sleep patterns. In 1938, Kleitman and post-graduate student Bruce Richardson lived for more than a month in Mammoth Cave in Kentucky to determine if humans could adapt to a twenty-eight-hour day in the absence of normal environmental cues of light and temperature change. They discovered that body temperatures fluctuate throughout the day, and that a person's peak efficiency coincides with peak body temperature. Kleitman continued this line of inquiry in 1948 when he spent two weeks aboard a submarine, the U.S.S. Dogfish, studying the relationship between mental alertness and temperature change. From May to July of 1951, Kleitman and his family lived in Tromso, in northern Norway, where he studied how long periods of exposure to daylight affected the sleep patterns of inhabitants of the Arctic Circle.
These studies influenced the conception and scheduling of shift work for soldiers and industrial workers. Kleitman's research also greatly impacted scientists' understanding of circadian and ultradian rhythms. He proposed a regular, 90-minute cycle of rest and activity - in sleep and wakefulness - which he called the basic rest-activity cycle (BRAC).
In 1953, Dr. Kleitman and student Dr. Eugene Aserinsky famously reported their discovery of rapid eye movement (R.E.M.) during sleep in their paper "Regularly Occurring Periods of Eye Motility, and Concomitant Phenomena, During Sleep," published in the journal Science. They demonstrated the correlation between R.E.M. sleep and dreaming. A 1956 study of R.E.M. sleep with student William C. Dement dispelled the notion that dreams last for only a few seconds (the average person dreams for two hours a night).
Dr. Kleitman remained active in his profession long after his retirement from the University of Chicago in 1960. He published his last article at the age of eighty-seven, and was a participant in D. L. Bliwise's study, "Sleep in a Nonagenarian: N. Kleitman" (Archives Italiennes de Biologie, 2001) from age eighty-six to ninety-four. In 1995, at the age of one-hundred, Kleitman was a special guest at the American Professional Sleep Societies meeting in Nashville, Tennessee. There, he was accorded great respect for his impact on the field, and he interacted with other significant sleep researchers including Michel Jouvet, and former students William C. Dement and Eugene Aserinsky.
Kleitman died on August 13, 1999 in Los Angeles, California.
This collection contains the papers of Nathaniel Kleitman, the father of sleep research. The collection is divided into 6 series.
Series I, Biographical, contains information on the life of Nathaniel Kleitman, including obituaries, interview texts, bibliographies and memorial publications.
Series II: Research and Writings, is organized by research topic and contains research data (charts, tables and graphs), article drafts, and notes of Nathaniel Kleitman. Here information from a wide variety of sleep research experiments can be found, including data collected both by Kleitman himself, as well as by his students and colleagues. Edited manuscripts of Kleitman's book Sleep and Wakefulness can be found in Boxes 4-7. This includes material from the 1962 revised edition. Oversized materials from this series are located in Boxes 35-46 of Series VI, containing Kleitman's bibliographic card catalog. A key to Kleitman's color code system used in his card catalog can be found in Box 15 Folder 8.
Series III: Print Publications is organized alphabetically and contains the printed materials Kleitman had collected. These include numerous clippings from newspapers and magazines containing references to sleep in articles, advertisements and cartoons. This series also contains Kleitman's collection of academic reprints, organized alphabetically. Boxes 16 and 17 contain reprints of Kleitman's writings. Oversized materials from this series have been moved to Series VI Boxes 47-49, including newspaper clippings from the Mammoth Cave experiment and other sleep articles.
Series IV, Artifacts and Memorabilia, is organized by format or document type. Here, Kleitman's travel documents, awards, certificates, graduation programs, medals and other memorabilia can be found. Oversized materials from this series have been moved to Series VI Boxes 50-54, including equipment used in Kleitman's research.
Series V: Audio-Visual and Photographs, is organized by format. The photographs in this series include family photographs of Kleitman throughout his life, as well as photographs from his research including ones documenting his time spent in Mammoth Cave. This series also includes audio recordings of Kleitman lectures, videocassette interviews and sleep specials. Oversized materials from this series, including two LP records, have been moved from this series to Series VI Box 53.
Series VI: Oversized Materials contains materials transferred from Series I-V. Descriptive headings can be used to trace these materials to their original locations in Series I-V.
