content: A spectrophotofluorometer is a complex instrument that measures the spectrum of fluorescent light reflected from a substance of interest. Robert L. Bowman and Sidney Udenfriend, a physician and a biochemist working at the National Heart Institute in the early 1950s, designed and tested the form. They then worked with Hugh King Howerton, an American Instrument Company physicist, to develop the instrument that was put on the market in 1956.
