Historical Significance: Hjalmar August Schi?tz (1850-1927) was born in Stavanger, Norway. He graduated in Medicine in 1877 in Khristiania. He studied ophthalmology in Vienna, where he became a friend of Ernst Fuchs (1851-1930), and in Paris, where he was employed as "directeur adjoint" in the ophthalmologic laboratory at the Sorbonne under Louis ?mile Javal. They developed the ophthalmometer named for them in 1880. In 1881 he became an assistant at the surgical department of the Rikshospitalet in Kristiania and he established a private practice as an eye specialist. He distinguished himself in his work to introduce asepsis in Norway. He was appointed professor of medicine with the obligation to teach eye medicine in 1901. Schi?tz demonstrated his tonometer in The Norwegian Medical Society (Det norske medicinske Selskab) in 1905 and for the next half century the Schi?tz tonometer was generally accepted as a reliable means of measuring intraocular pressure.
