Abstract Thomas B. Fitzpatrick had a tremendous influence on the specialty of dermatology, including seminal scientific contributions, a legendary ability to teach and train, and remarkable innovations in clinical dermatology. Born in Wisconsin in 1919, he received his medical degree from Harvard, followed by a PhD in pathology. He served 2 years at an Army Chemical Centre, where his interest in skin pigmentation led to the discovery of human tyrosinase. Further innovation in basic sciences followed, with the discovery of the melanosome and epidermal melanin unit. He added to his academic accolades by completing a fellowship in chemistry at Oxford, then returned to the USA to pursue clinical dermatology training at Mayo Clinic. At the age of 32 years, following substantial success in his early career, he was appointed Professor and Chair of Dermatology at the University of Oregon. By 39 years of age, he was Chair of the Harvard Medical School Dermatology Department, Harvard’s youngest Professor and Chair, while serving as Chief of Dermatology at Massachusetts General Hospital. He was a master at motivating students and sharing his passion for dermatology. He often said ‘Practicing dermatologists are like the woodwind section of the orchestra—small in number, when they play they must play well’. In 1971, he wrote the first multiauthor medical textbook in the field entitled Fitzpatrick’s Dermatology in General Medicine, now in its eighth edition. Dr Fitzpatrick contributed heavily to the clinical advances in dermatology in the latter half of the 20th century. Alongside dermatopathologist Wallace Clark, he established the very first pigmented lesion clinic in 1966. From that clinic, studies enabled Dr Clark to devise the Clark level staging system for melanoma. Fitzpatrick described early diagnostic signs in melanoma, and the concept of sunlight as a factor in its aetiology. In 1975, he devised the Fitzpatrick scale of skin phototypes, which described a person’s skin type in terms of response to ultraviolet (UV) radiation exposure. To huge success, he experimented with psoralen and UVA to treat psoriasis, coining the term photochemotherapy, or PUVA. Fitzpatrick was a highly productive medical scholar, while having many other notable qualities and interests. He was an avid lover of music, a skilled pianist and a Johannes Brahms enthusiast. The Boston Globe called him a ‘dermatologist with an infectious enthusiasm for his specialty and philosopher’s love of a good quote’. For 20 years, he co-edited the Globe’s popular ‘Reflection for the Day’, alongside his loving wife Beatrice. Thomas Fitzpatrick was admired by many until his passing in 2003, leaving us with so much to remember him by.
