Inventor John Haven “Jack” Emerson refined Phillip Drinker and Louis Agassiz Shaw’s original 1927 invention: the Drinker Respirator, designed to treat polio. Emerson’s company made the blue iron lung or Emerson Negative Pressure Ventilator. It was more efficient, lighter, quieter and half the cost at $1,000. The blue iron lung was first used on a polio patient in 1931. After using the device, many polio patients were able to breathe on their own again. A few remained dependent upon the machines.
