He studied, taught, and wrote textbooks and scholarly works on a variety of topics in industrial hygiene; [2] the iron lung itself was originally designed in response to an industrial hygiene problem—coal gas poisoning [2] —though it would become best known as a life-preserving treatment for polio.
