The AASM regrets to announce the passing of longtime AASM member and sleep medicine pioneer Christian Guilleminault, MD. As reported by the World Sleep Society, Dr. Guilleminault died at the age of 80 on July 9, 2019, from complications due to metastatic prostate cancer. He is survived by his wife, Priscilla Grevert, and his two sons, Eric and Damian Guilleminault.

As both a clinician and scientist, Dr. Guilleminault played a foundational role in the establishment and development of the field of sleep medicine. In 1970 he opened one of the world’s first sleep disorders centers in Paris, and in the early 1970s he helped establish the first full-service sleep disorders clinic in the U.S. at Stanford University, as described in the History of the Development of Sleep Medicine in the United States.

Reflecting on the legacy of Dr. Guilleminault, whom many colleagues called “CG,” Rafael Pelayo, MD, remembered his steadfast commitment to patient care.

“I recall as a fellow when I started working with CG in 1993, that I was struck how he treated each patient with the interest and curiosity as if he was seeing sleep apnea for the first time,” said Dr. Pelayo, a clinical professor in the Stanford University School of Medicine who worked alongside Dr. Guilleminault at the Stanford Center for Sleep Sciences and Medicine. “He had seen countless patients, but still never seemed to lose his fascination with sleep apnea or his interest in helping his patients. I don’t think he ever lost that curiosity.”

In 1976 Dr. Guilleminault was appointed to a joint Nosology Committee of the AASM and the Sleep Research Society to develop a diagnostic system for clinical sleep disorders. The committee published its Diagnostic Classification of Sleep and Arousal Disorders in September 1979. Their efforts laid the groundwork for the publication in 1990 of The International Classification of Sleep Disorders (ICSD). Dr. Guilleminault served on the AASM Diagnostic Classification Steering Committee that developed the manual, which is now in its third edition (ICSD-3) and remains the official diagnostic classification for the sleep field.

In the late 1970s, Dr. Guilleminault and Dr. Dement became the founding editors of the journal Sleep. After serving as co-editor from 1978 to 1992, Dr. Guilleminault began a five-year term as editor-in-chief in 1993, completing his service in 1997.

“He was a dedicated clinician, a father for his students, fellows, clinicians and researchers,” said Maurice Ohayon, MD, DSC, PhD, director of the Stanford Sleep Epidemiology Research Center. “Christian Guilleminault was a formidable human being who will be remembered for his tremendous accomplishments in sleep medicine.”

Dr. Guilleminault also helped develop the first examination in clinical polysomnography, administered by the AASM in 1978. Eventually, it became the sleep medicine certification exam of the American Board of Sleep Medicine (ABSM), and today the exam is offered by six member boards of the American Board of Medical Specialties (ABMS).

“His tireless efforts as an educator, his monumental contributions to the scientific study of sleep, his seminal work in obstructive sleep apnea and other sleep disorders, and his leadership in international sleep organizations will not be forgotten,” said AASM Past President Clete Kushida, MD, PhD, division chief and medical director of Stanford Sleep Medicine and director of the Stanford Center for Human Sleep Research.

A renowned sleep researcher, Dr. Guilleminault made significant contributions to the understanding of the physiological and endocrinological changes that occur during sleep. His extensive body of research also included studies of obstructive sleep apnea, pediatric sleep disorders, and narcolepsy.

“Christian perfected the definition of an ideal clinician and scientist,” said Michelle Cao, DO, clinical associate professor in psychiatry and behavioral sciences at the Stanford Center for Sleep Sciences and Medicine. “His intellectual pursuit of science was unmatched and unwavering.”
