Jean-Jacques-Joseph Leroy d'Etiolles

Jean-Jacques-Joseph Leroy d'Etiolles (5 April 1798 in Paris – 25 August 1860) was a French surgeon who studied and practiced medicine in Paris.

He is credited with the invention of numerous medical devices, including a lithotriptic instrument (1822), that was improved upon and put to successful use by Jean Civiale (1792–1867) soon afterwards. He is also known for pioneer experiments involving barotrauma produced by mechanical ventilation.
