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.

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.

Some of his principal studies included:

  • Scattering of X-rays by matter;
  • Development of the Ross differential filter for X-ray spectroscopy;
  • X-ray polarization;
  • Compton scattering; and
  • Radiative Auger effect.
  • His daughter, Betsy, married fellow Stanford physicist William Webster Hansen.
