Clair Loring Farrand (1895-1981), an inventor best known for his work with the cone loudspeaker, began his career as a Marconi radio operator. He established the Farrand Optical Company in 1941, bought a factory in the Bronx, and made optics for the U.S. Army and Navy during World War II. The firm moved to Mount Vernon, New York, in the mid-1960s.
Farrand began manufacturing fluorometers in the 1950s. The inscription on this example reads “Fluorometer / MODEL A SER 202 / FARRAND OPTICAL / NEW YORK / PAT. PEND.”
