Heinrich von Recklinghausen

Heinrich von Recklinghausen (17 April 1867 – 12 December 1942) was a German physician and scientist from Würzburg.

During World War I he was a military physician in Strasbourg, and afterwards performed scientific research in Heidelberg and Munich.

During the 1930s he devised an oscillo-tonometer, a device used to measure systolic and diastolic blood pressure.

[1] With Recklinghausen's oscillotonometer, a stethoscope was not needed to listen for Korotkoff sounds; they were instead represented as oscillations of a needle.

Although he published no books on these subjects, he left behind copious notes concerning his beliefs, and maintained an ongoing correspondence with philosophers Heinrich Rickert (1863–1936), Paul Hensel (1860–1930), and Albert Schweitzer (1875–1965).
