In 1930, Henrik Sjögren (1899-1986), an ophthalmologist in Jönköping, Sweden, observed a patient with low secretions from the lacrimal and salivary glands [REF].
After extensive research and data collection, Sjögren published an essential paper in 1951, describing 80 patients with keratoconjunctivitis sicca, 50 of whom also had arthritis [REF].
