Gene D. Cohen (1944–2009) was an American psychiatrist who pioneered research into geriatric mental health. He was the first head of the Center on Aging at the National Institute of Mental Health, the first government-supported center on mental health and aging in the world, and was later the first director of the Center on Aging, Health, and the Humanities at the George Washington University.
Cohen was born on September 18, 1944 in Brockton, Massachusetts, where he showed a predilection for science at an early age. He attended Harvard College as an undergraduate, earning his degree in 1966, and four years later graduated from the Georgetown University School of Medicine.
Cohen worked for a time in the United States Public Health Service before becoming the founding Director of the Center on Aging at the National Institute of Mental Health in 1975. In 1981, he earned a Doctorate in Gerontology at the Union Institute and University. He went on to serve as Acting Director of the National Institute on Aging at the National Institutes of Health from 1991-1993 and found the Center on Aging, Health, and the Humanities at the George Washington University in 1994.
Cohen was a dedicated advocate of the idea that the aged are capable of functioning at high levels of creativity and intellectual rigor. When his career began, the medical profession largely treated aging like a disease, but Cohen argued based on his research that the brain would continue creating new cells at any age so long as it was engaged in new and challenging intellectual activities. His work in a number of studies on aging supported this belief, including a 2002 study which suggested that involvement in the arts late in life led to a lower incidence of illness and injury. According to Dr. Walter Reich, a colleague at George Washington University, "Single-handedly he changed the image of aging from one of senescence to a period of creativity."
