Biography of Carl-Olof Siggesson Nylén

Carl-Olof Nylén is reckoned as one of the founders of microsurgery. In 1921, in the university ear, nose, throat clinic in Stockholm, he built the first operational microscope, a modified monocular Brinell-Leitz microscope for intraoperative use in animals. In November 1921, Nylen used it for a microsurgical operation in a case of chronic otitis with labyrintic fistula. Nylen's microscope was soon replaced by a binocular microscope developed in 1922 by his colleague Gunnar Holmgren (1875-1954).
