In this letter, Dr. Prentiss inquires about the possibility of combining a moisture detector and an oxygen meter, presumably for use in submarines. At the time, Dr. Spencer S. Prentiss was working for the National Defense Research Committee (NDRC) as a patent liaison and researcher on various oxygen-related projects.
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.
