Above: Dr. Jean-Louis-Paul Denucé's incubator for premature infants, Bordeaux, ca. 1857. Essentially a double-walled tub, separated by a closed space that can be filled with warm water. This is the first known reference to an incubator in the Western medical literature.
Above: Dr. Stéphane Tarnier's first incubator came into regular use at the Maternité of Port Royal in Paris in 1881. The lower half was occupied by a large tank of hot water.
