Description
In the late 1930s, Linus Pauling realized that he could use the fact that oxygen is affected by magnetic fields to measure the oxygen content of a sample of air. After building a few prototypes, Pauling asked Arnold O. Beckman, his colleague in the chemistry department at the California Institute of Technology, to develop a commercial model. Arnold O. Beckman, Inc. was formed in 1942, expressly for this purpose; and Pauling oxygen analyzers were widely used in submarines and aircraft during World War II. The Model D2 was introduced in 1956; and the Model E2 a few years later. The inscription on the front of this example reads “Arnold O. Beckman Inc. / OXYGEN ANALYZER / MODEL E-2.” A tag on the back reads “Ser. No. 16.”
