The isolation and naming of the hormone melatonin in 1958 established a significant milestone in endocrinology led by American physician and researcher Aaron Bunsen Lerner. His work focused on the metabolic foundations of skin conditions, bridging the gap between basic chemical research and clinical dermatology practice within major academic institutions in the United States.
Academic Foundations and Early Career
Born in Minneapolis in 1920, Lerner pursued a rigorous academic path that culminated in 1945 at the University of Minnesota, where he earned both a medical degree and a PhD in chemistry. Following this dual education, he held teaching positions at the University of Michigan and the University of Oregon. These appointments provided the groundwork for his transition to the Yale University School of Medicine in 1955, where he served as an associate professor.

Upon joining the Yale faculty, Lerner became the director of the dermatology section within the Department of Internal Medicine. His organizational contributions were formally recognized in 1971 when the Department of Dermatology was established as an independent entity; he was named its first chair. He maintained this leadership position until his retirement in 1991, at which point he was granted the status of Professor Emeritus of Dermatology. In 1973, his scientific contributions were recognized with an election to the National Academy of Sciences, specifically in the fields of medical physiology and metabolism.
Scientific Research and Clinical Application
Lerner is noted for his identification of the melanocyte-stimulating hormone, known as MSH. His expertise extended to the study of inherited diseases, with a specific focus on vitiligo. During the 1980s, he successfully developed a skin transplantation therapy intended to address this condition. His research remains a cornerstone for understanding pigmentary metabolic pathways.
