Marion Amelia Spence Ross FRSE (9 April 1903 – 3 January 1994) was a Scottish physicist noted for her work in x-ray crystallography and fluid dynamics.
[4] For one year, she worked under the direction of William Lawrence Bragg at the University of Manchester, and together with Arnold Beevers, explored the structure of the crystal Beta Alumina.
Her proposers were Norman Feather, Max Born, Alexander Aitken and Sir Edmund Taylor Whittaker.
[9] Outside her professional life, Ross had a wide range of interests, including literature, art, music, and politics.
She was particularly interested in the organ that her father had designed for the Holy Rude Church, Stirling, where he was the organist, and where Ross sang in the choir.
Her research in nuclear and X-ray physics, and in fluid dynamics, is internationally recognised and has inspired others to follow in her footsteps.
