In his research, Professor Walter Guyton Cady made discoveries and studies that formed the basis of the fields of all three of the UFFC Society sections. Ultrasonics: Underwater ultrasonics (1917). Ferroelectrics: Piezoelectric effect in Rochelle salt (1937). Frequency control: Quartz resonator (1922). This page is dedicated to the memory of Walter Guyton Cady.
