Edward Neville da Costa Andrade FRS (27 December 1887 – 6 June 1971) was an English physicist, writer, and poet. He told The Literary Digest his name was pronounced "as written, i.e., like air raid, with and substituted for air." In the scientific world Andrade is best known for work (with Ernest Rutherford) that first determined the wavelength of a type of gamma radiation, proving it was far higher in energies than X-rays known at the time. Also, a rheological model suggested by him and bearing his name is still widely employed in continuum mechanics and its geophysical applications. In popular culture he was best known for his appearances on The Brains Trust.
