Ueber einen neuen Blutdruckmesser (Tonometer). Contained in: Wiener Medicinische Wochenschrift, No. 30, pp. 1412-1417, July 1899. by GAERTNER, Gustav. (1855-1937) - 1899

(Wien:: Moritz Perles), 1899., 1899. Large 8vo. (330 x 252 mm) pp. 1402-1448. 1 text fig. (this article); edges browned. Stapled self-wraps; folded crosswise. Very good. The invention of the Tonometer, a device for measuring blood pressure from the finger. Gaertner was an Austrian pathologist who is remembered for his work in experimental pathology, including the study of kidney functions, experiments concerning electrical skin resistance and his work with innervation of cerebral vessels. Gaertner is credited with the creation of numerous medical devices and apparati, the best-known invention being a tonometer which contained an inflatable finger cuff for measurement of blood pressure. A specialized version of Gaertner's tonometer is presently used in ophthalmology to determine intraocular pressure. Gustav Gaertner studied in Vienna and received his doctorate in 1879. He received his training in experimental pathology under Salomon Stricker (1834-1898) and in 1882 became Stricker's assistant. His scientific work in this period included studies of the splanchnic innervation of the kidney, kidney secretion, the electric resistance of the skin and innervation of the vessels of the brain. His research into nutrition produced important results. However, Gaertner distinguished himself particularly in his inventions of medical apparatuses, of which several are named for him. In 1886 Gaertner became a Privatdozent in experimental pathology, in 1890 professor extraordinary, and in 1918 full professor in Vienna. Garrison & Morton 2810.
