Albert M. Kligman: 90 Years Old on March 17, 2006

Albert M. Kligman, who celebrated his 90th birthday on March 17, 2006, was a significant figure in dermatology, known for his academic contributions, generosity, and some controversy. His most notable research accomplishments include the development of topical tretinoin for acne and photodamaged skin, the periodic acid-Schiff stain for visualizing fungi in tissue, descriptions of the human hair cycle, telogen effluvium, and hot comb alopecia, studies on the pathogenesis of acne vulgaris, the maximization test for identifying contact allergens, and coining the terms "photoaging" and "cosmeceuticals." Kligman's work debunked dermatologic myths, such as the belief that chocolate causes acne. He trained many leaders in dermatology and was generous in his support for medical education and research. His vision for a more scientific approach to dermatology has had a lasting impact on the field.
