Jean-Jacques-Joseph Leroy d'Etiolles

Jean-Jacques-Joseph Leroy d'Etiolles (5 April 1798 in Paris – 25 August 1860) [1] 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.

[2][3] He is also known for pioneer experiments involving barotrauma produced by mechanical ventilation.
