Henrik Sjögren

Henrik Samuel Conrad Sjögren was a Swedish ophthalmologist best known for describing the eponymous condition Sjögren's disease, previously known as Sjögren syndrome. His first experience with the disease was an encounter with a 49-year-old woman with arthritis and extreme dryness of the mouth and eyes. He presented 19 similar cases for his doctoral theses in 1933 that eventually served as the basis of identifying and naming of Sjögren syndrome.
