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.

Giovanni Domenico Santorini
Insert text here

Giovanni Domenico Santorini (1681 – 1737). Italian anatomist, Santorini was born in 1681 in Venice. The son of an apothecary, Santorini studied medicine at Bologna and Padua, receiving his doctorate in Pisa in 1701. He was appointed Public Professor of Anatomy at the Physicomedical College of Medicine when he was 22 years of age.

Santorini was praised for the clarity of his lectures and his dexterity as an anatomist.  He used magnifying glasses to study minute anatomical details, allowing him to clearly describe small structures hitherto unknown. Most of Santorini’s biographical data was written by Michael Girardi (1731 – 1797), one of his students. Girardi published Santorini’s work posthumously in 1775 in the book “Anatomici Summi-Septendecim Tabulae”.

Santorini’s himself wrote “Opuscula medica de structura” (Minute Medical Structures) in 1705. His most important book was “Observationes anatomicae”, published in Venice in 1724. One of the most interesting chapters in this book was “De mulierum partis procreationes datis” (Data on the female procreational structures ), making him a pioneer in the teaching of obstetrics. Santorini was physician to the Spedaletto (Hospital) of Venice, where he taught midwifery.

Santorini died in 1737 because of an infection he acquired during the dissection of a cadaver. At that time the rationale for infection and cadaver embalming were unknown.

With his posthumous publications, Santorini’s name and teachings became popular. Today his name is eponymically tied to several structures in the human body:

• Duct of Santorini: An accessory pancreatic duct that opens into a secondary duodenal papilla in the second portion of the duodenum
• Santorini’s valves: Mucosal folds found in the lumen of the primary duodenal papilla (of Vater) or hepatopancretic ampulla
• Santorini’s muscle: Risorius muscle • Santorini’s cartilages: The laryngeal corniculate cartilages
• Santorini’s veins: A plexus of vesicoprostatic veins found in the retropubic space) of Retzius
• Santorini’s concha: The superior nasal turbinate
