August Siegrist

August Siegrist (1865 to 1947) was a Swiss ophthalmologist remembered for describing Siegrist streaks. Born in Basel, he trained at Basel, Zurich, Lausanne, Vienna and Bern, where he received his medical doctorate in 1892, and he studied further under Emil Theodor Kocher in Bern and Ernst Fuchs in Vienna. He qualified as a university lecturer in ophthalmology at Basel in 1900, and in 1903 he succeeded Ernst Pflüger as professor of ophthalmology and director of the eye clinic at the University of Bern, holding both positions until 1935. His work included the correction of keratoconus, among it the use of early contact lenses.
