Blizzard was an early proponent of growth hormone therapy in children with growth hormone deficiency; his New York Times obituary said that he "liked to say that he had helped add 11 miles of height to the United States population" through growth hormone therapy.[1] He advocated for a formalized process for sourcing human growth hormone from cadaver pituitary glands, and in 1961 he co-founded the National Pituitary Agency, a branch of the National Institutes of Health.[1][3] In 1978 he conducted one of the first trials of growth hormone use in adults, wondering about its anti-aging effects, but did not find any benefits.[1] He proposed the theory of "psychosocial dwarfism" after reporting on a reversible form of hypopituitarism seen in children who had endured severe emotional stress,[3] and established a program in Virginia in which school nurses measured children's heights as a screening tool for domestic abuse.[1] He gave his name to Johanson–Blizzard syndrome, which was first described by Blizzard and Ann J. Johanson in 1971.[4]
