Thomas Caspar Gilchrist (15 June 1862 – 14 November 1927), was professor of dermatology at the University of Maryland before taking up the same position at the Johns Hopkins Hospital, Baltimore. He wrote on acne, erysipelas, X-ray dermatitis, porokeratosis, sarcoma of skin, and fatty atrophy. The fungal infection Gilchrist's disease, more commonly known as blastomycosis, is named for him after he first mistook it as a protozoan disease before correctly identifying it as a fungal in origin. The organism that causes it, blastomyces dermatitidis was subsequently described by him and William Royal Stokes back in 1894. ^[1][2][3][4]
