Courvoisier's law, a fundamental clinical sign in biliary diagnostics, originated from a detailed manual published by Swiss surgeon Ludwig Georg Courvoisier in 1890. This diagnostic principle established that a painless, enlarged gallbladder is typically indicative of a condition other than gallstone obstruction, a finding that significantly refined surgical approaches to the biliary tract during the nineteenth century.
Medical Education and Early Training
Born in Basel in 1843, Courvoisier attended the local Gymnasium before enrolling at the University of Basel. His academic progression experienced several interruptions, including a bout of typhus, service in the Austro-Prussian War, and a semester at the University of Göttingen. Under the instruction of August Socin, he completed a prize-winning thesis titled The Histology of the Sympathetic Nervous System. After earning his M.D. in 1868, he pursued postgraduate training in London with Sir William Ferguson and Sir Thomas Spencer Wells, followed by a year in Vienna under the mentorship of Theodor Billroth and Vincenz Czerny. During the Franco-Prussian War in 1870, he served at a German military hospital in Karlsruhe.

Take the IQ test →Contributions to Biliary Surgery
Courvoisier focused his professional career on biliary tract pathology. In 1888, the University of Basel appointed him as a professor of surgery. His landmark text, Casuistisch-statistische Beiträge zur Pathologie und Chirurgie der Gallenwege, compiled his research and observations on biliary surgery. Beyond introducing the clinical sign that bears his name, he gained recognition for his technical work as one of the first surgeons to successfully remove gallstones from the common bile duct.
Scientific Interests in Entomology
Beyond his medical practice, Courvoisier maintained a rigorous engagement with entomology and botany, interests that began during his childhood residency in Malta. He focused his scientific study on the Lycaenidae family of butterflies. Between 1910 and 1920, he authored numerous papers regarding the taxonomy, characteristics, and distribution of these insects, including works on Javanese species and wing aberrations. His extensive collection of butterfly specimens and his herbarium remain preserved at the Natural History Museum of Basel.
