Robert Tigerstedt

Robert Adolph Armand Tigerstedt (born February 28, 1853 in Helsinki ; † February 12, 1923 there ) was a Finnish physiologist . He became known for the discovery of the enzyme renin , which he and his student Per Bergman made at the Karolinska Institute in 1898 .

General

Tigerstedt was an internationally respected physiologist in his day, whose textbooks were standard works. In particular, he dealt with the physiology of the blood circulation, but also with nutrition and metabolism. So he invented a respiratory apparatus for measuring the breathing gases, the Tigerstedt probes respiratory apparatus .

He also worked as a social reformer and was a member of the abstinence movement .

biography

His father Karl Konstantin Tigerstedt was a history professor at the University of Helsinki . Robert Adolph Armand Tigerstedt went to high school in Turku and then studied natural sciences at the University of Helsinki, among others with the chemist Carl Axel Arrhenius . After graduating in 1876, he studied medicine in Helsinki and received his doctorate in 1881 with a dissertation on mechanical nerve stimulation . In 1881 he went to Stockholm at the Karolinska Institute in the Physiology Department, where he was initially assistant to Christian Lóven (1835-1904) and in 1886 he succeeded him as professor. In 1901 Tigerstedt returned to Helsinki, where he succeeded Konrad Hällstén (1835-1913). From 1916 to 1919 he was dean of the medical faculty. In 1918 he worked as a doctor in a Finnish prisoner-of-war camp and wrote a critical report about it. In 1919 he retired, but remained scientifically active until he died of a heart attack in 1923.

Tigerstedt had been married since 1878 and had three children.

In 1912 Tigerstedt received the Cothenius Medal . In 1890 he became a member of the Royal Swedish Academy of Sciences . He has been nominated twice for the Nobel Prize and has received several honorary doctorates (Tartu, Dublin, Oslo, Helsinki, Groningen). In 1919 he was elected a member of the Leopoldina . In 1922 he was elected a corresponding member of the Göttingen Academy of Sciences and the Bavarian Academy of Sciences .

The Robert Tigerstedt Award of the International Society of Hypertension is given in his honor.
