Paul Altmann was a Berlin manufacturer of incubators that were widely used at expositions and "incubator sideshows" around the turn of the century. Altmann was an instrument maker for Robert Koch, discoverer of the bacterium that causes tuberculosis. The incubators were adapted from Alexandre Lion's design, but had a distinctive appearance that turns up in numerous early engravings and photographs. Later, the incubators were apparently manufactured by the Kny-Scheerer Co. of New York under license.
"The Lion Incubator manufactured by Paul Altmann was warmed by a cylindrical 'water-boiler' mounted on the outer wall of the unit and the infant's cabinet was ventilated by fresh air blown through a large pipe by an electric fan on the outside of the building; the air entered the incubator through a metal box attached to the side of each cabinet. Here the air was moistened by being passed through a layer of absorbent wool suspended over a saucer containing water. From this filtering box the air passed into the bottom and center of the incubator where it was diffused and passed over the surface of hot-water coils from the external heater, and then flowed into the infant's compartment in the upper part of the incubator. On the top of the incubator an outlet "chimney" was fitted with fan-blades which allowed only one-way passage of an upward current of exhaust air."
