A Moment in History

Georg Eduard Von Rindfleisch

Georg Eduard Von Rindfleisch
(1836 – 1908)

German pathologist and histologist of Bavarian nobility ancestry. Rindfleisch studied medicine in Würzburg, Berlin, and Heidelberg, earning his MD in 1859 with the thesis “De Vasorum Genesi” (on the generation of vessels) under the tutelage of Rudolf Virchow (1821 - 1902). He then continued as a assistant to Virchow in a newly founded institute in Berlin. He then moved to Breslau in 1861 as an assistant to Rudolf Heidenhain (1834–1897), becoming a professor of pathological anatomy. In 1865 he became full professor in Bonn and in 1874 in Würzburg, where a new pathological institute was built according to his design (completed in 1878), where he worked until his retirement in 1906.

He was the first to describe the inflammatory background of multiple sclerosis in 1863, when he noted that demyelinated lesions have in their center small vessels that are surrounded by a leukocyte inflammatory infiltrate.

After extensive investigations, he suspected an infectious origin of tuberculosis - even before Robert Koch's detection of the tuberculosis bacillus in 1892. Rindfleisch 's special achievement is the description of the morphologically conspicuous macrophages in typhoid inflammation. His distinction between myocardial infarction and myocarditis in 1890 is also of lasting importance.

Associated eponyms

"Rindfleisch's folds": Usually a single semilunar fold of the serous surface of the pericardium around the origin of the aorta. Also known as the plica semilunaris aortæ.

"Rindfleisch's cells": Historical (and obsolete) name for eosinophilic leukocytes.

Personal note: G. Rindfleisch’s book “Traité D' Histologie Pathologique” 2nd edition (1873) is now part of my library. This book was translated from German to French by Dr. Frédéric Gross (1844-1927) , Associate Professor of the Medicine Faculty in Nancy, France. The book is dedicated to Dr. Theodore Billroth (1829-1894), an important surgeon whose pioneering work on subtotal gastrectomies paved the way for today’s robotic bariatric surgery. Dr. Miranda.

Adam Christian Thebesius

Adam Christian Thebesius (1686- 1732). German physician and anatomist, Thebesius studied in the University of Leiden, Netherlands, where he received his doctorate in 1708 with the thesis "De circulo sanguinis in corde" (on the circulation of the blood in the heart). In 1713 he became a member of the Royal Academy of Natural Scientists (Kaiserliche Akademie der Naturforscher), where he adopted the Latin name "Eyryphon". Besides his natural sciences and medical research, Thebesius developed an interest in astrophysics.

Extremely interested in coronary circulation, Thebesius injected dyes and fluids in the coronary arteries, veins, and coronary sinus. Along with Raymond Vieussens (1635-1713) , Thebesius described all these structures. Today his name is attached to the eponymic Thebesian veins (venae cordi minima), and the Thebesian valve guarding the exit of the coronary sinus into the right atrium of the heart. Both these structures were mentioned in his 1708 doctoral thesis
