Perley Ason Ross

Perley Ason Ross (6 April 1883 – 13 March 1939) was a U.S. experimental physicist who worked, carefully and without seeking publicity, at some essential problems in the behaviour of X-rays.^[1]

Born in Panacea, Missouri he was awarded his PhD from Stanford University in 1911, becoming a full professor there in 1927, after a year at Cornell University.^[1]

Some of his principal studies included:

• Scattering of X-rays by matter;^[1]
• Development of the Ross differential filter for X-ray spectroscopy;^[1]
• X-ray polarization;^[1]
• Compton scattering;^[2] and
• Radiative Auger effect.^[3]

His daughter, Betsy, married fellow Stanford physicist William Webster Hansen.^[4]
