Incubators at the Maternity Hospital, Port Royal, Paris (Maternité de Paris, Port-Royal). An engraving from the Illustrated London News, March 8, 1884, and attributed to Eugene Froment (1844-1900). Interestingly, the same engraving also appeared in the March 8, 1884 issue of Le Monde Illustré, Paris, but was there attributed to M. Claverie. The incubators were invented by Stéphane Tarnier in 1880, and documented by Auvard in the historic 1883 article De La Couveuse Pour Enfants.
