Abstract
THE production of electric charges on certain crystals by the application of pressure was discovered by the brothers Curie in 1880. Until the First World War the phenomena were of scientific interest only, but with the researches of Langevin and Rutherford the use of ultrasonic waves became important in warfare at sea. Between the two Wars piezoelectricity became of great importance to radio in the control of frequency. During the Second World War millions of piezoelectric crystals were made for use in communications both by radio and by telephone. Corresponding to this intense industrial activity there has been a great development of the theoretical aspects of the subject.
