E. T. S. Appleyard

Dr. E. T. S. Appleyard (1904 - 15 June 1939) was a physicist and pioneer in the fields of thin films and superconductivity.

Career and Profession

Dr. E. T. S. Appleyard was born in 1904, the son of Edgar Snowden and Elizabeth Appleyard of Huddersfield, England.

Appleyard attended Almondbury Grammar School and then was admitted to the Cambridge as a King’s College scholar. In the Natural Science Tripos he selected Physics as one of the key science subjects to focus his interest. He spent several years on research in the Cavendish Laboratory. In 1929 at the University of Bristol's H.H. Wills Physics Laboratory, Appleyard received an appointment to a George Wills research associateship.^[1] He held this post until an accident resulted in his untimely death in 1939. At the University of Chicago for the 1931-1932 academic year, Appleyard was awarded with a Rockefeller fellowship.^[2]
