The SRS is deeply saddened to announce the passing of distinguished insomnia specialist, Dr. Jack Edinger.  Dr. Edinger’s groundbreaking work focused on nature, classification, and management of insomnia disorders. He served as an advisor to the Sleep Disorders Workgroup of the America Psychiatric Association’s Diagnostic and Statistical Manual, 5th Edition. Dr. Edinger was also a member of the International Classification of Sleep Disorders, 3rd Edition task force, where he chaired the insomnia section. Dr. Edinger will be greatly missed by colleagues and the broader sleep and circadian research community.
