A Moment in History

Antoine Louis

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.

Sylviane Déderix. Ph.D.

Dr. Sylviane Déderix is a Postdoctoral fellow at Catholic University of Louvain in the Aegean Interdisciplinary Studies Research Group. She has a Ph.D. in History, Art, and Archeology.

She is also a collaborator of the Laboratory of Geophysical- Satellite Remote Sensing & Archaeoenvironment and a member of the Sissi Archaeological Project (Crete, Greece)  in charge of the architectural study of the house tombs excavated in the cemetery.

She has collaborated with the effort of finding the lost grave of Andreas Vesalius using satellite imagery and geophysical approaches to pinpoint the location of the cemetery of the Church of Santa Maria delle Grazie after the island of Zakynthos was practically destroyed by an earthquake in 1953.

Dr. Sylviane Déderix

Since then the island and its buildings have been rebuilt and streets relocated, which causes the cemetery to have been lost until her work was published. Now we know the approximate location of the cemetery close to the current intersection of the Kolokotroni and Kolyva streets, and further studies can be conducted.

Thanks to Dr. Déderix for collaborating with "Medical Terminology Daily" with the article "In Search of Andreas Vesalius, The Quest for the Lost Grave - The Sequel" which she co-authored with Pascale Pollier and Theo Dirix.
