Too little oxygen has obvious repercussions, but until the 1950s doctors did not realize that too much oxygen caused retrolental fibroplasia, resulting in blindness. Developed from a Linus Pauling design during WWII, the technology behind Beckman Instruments’ oxygen analyzers ended up doing such diverse jobs as monitoring astronauts’ respiration, maintaining packaged food safety, and preventing blindness in newborn babies.
