A Moment in History

Antoine Louis
(1723–1792)

French surgeon, anatomist, and physiologist. Following his medical studies and a long career as a physiologist, Antoine Louis was named Permanent Secretary of the Royal French Academy of Surgery. His other titles were those of Professor of the Royal Academy, Consultant Surgeon of the Armies of the King, member of the Royal Society of Sciences of Montpellier, Inspector of the Royal Military Hospitals, and Doctor in Law of the University of Paris. As a member of these academies Louis was instrumental in the design and construction of the guillotine. Initially called the "Louisette", this device was later named after another French physician in the same committee, Dr. Joseph-Ignace Guillotin.

Antoine Louis' name is better know to history as the eponymic origin of the "sternal angle" also know as the "Angle of Louis" and synonymously (probably by misspelling or translation) the "angle of Lewis", and "angle of Ludwig". This anatomical landmark is extremely important as it serves as a superficial landmark for important anatomical occurrences (click here).

As a point of controversy, there are some that contest the history of this eponym adjudicating it to Pierre Charles Alexander Louis (1787-1872), another French physician dedicated to the study of tuberculosis.

Wilhelm Kiesselbach


This article is part of the series "A Moment in History" where we honor those who have contributed to the growth of medical knowledge in the areas of anatomy, medicine, surgery, and medical research.To search all the articles in this series, click here.

Wilhelm Kiesselbach (1839 – 1902) German otolaryngologist born in the city of Hanau. Started his medical studies in 1859 in Göttingen. Marburg, and Tübingen. Because of an accident that affected one of his hands and legs, his doctorate was delayed until 1875.

He specialized in otolaryngology in Vienna, although he also studied and specialized in ophthalmology. He had a number of positions such as assistant professor at the Medical Polyclinic in Erlangen, assistant professor for ophthalmological examinations at the Surgical Clinic in Erlangen, and senior physician for ophthalmology.

He died of an infection he contracted while working with patients at the clinic.

His name is eponymically tied to the locus Kiesselbachii, also known as Kiesselbach’s plexus, an area of the anteroinferior nasal septum known for propensity for epistaxis or nasal bleeding. In fact, close to 90% of nose bleeds happen in this area. in this region, terminal branches of the anterior ethmoid artery, greater palatine artery, sphenopalatine artery and superior labial artery anastomose forming a plexus.
