The AES recognizes and honors those who have made outstanding
contributions to the field of audio in engineering, technology,
service, and the arts through its Awards Program.
In 1957, Harry Nyquist was presented with the
AES Honorary Membership Award for his important work on thermal noise, the stability of feedback amplifiers, telegraphy, facsimile, television, and other important communications problems. In 1932 he published a classical paper on stability of feedback amplifiers. The Nyquist stability criterion can now be found in all textbooks on feedback control theory.
