Photograph of Thomas Gold (1920–2004) who, over a long active career, studied biophysics, astronomy, aerospace engineering, and geophysics. Gold was born in Austria and moved with his family to England where he studied at Cambridge. He contributed to the British war effort by working on improvements to radar. While working with R. J. Pumphrey after the war, Gold concluded that an electromechanically active mechanism was necessary to counteract viscous damping by cochlear fluids. Photograph provided by Professor David Kemp.
