Dr. Walter Guyton Cady was born in Providence, R.I. He received a bachelor’s degree from Brown University in 1895 and a master’s in 1896. After teaching there for two years, he went to the University of Berlin, where he received his Ph.D. in Physics in 1900. Dr. Cady spent two years with the Coast and Geodetic Survey and joined the faculty of Wesleyan University, Middletown, Connecticut in 1902. He served as Associate Professor from 1903 to 1907, and as Professor from 1907 to 1946. During this time he did pioneering work in the area of piezoelectricity, and development of practical devices using the piezoelectric effect. He was one of the earliest workers in frequency selection and control and devised the first crystal-stabilizied circuit, as well as one of the earliest crystal-controlled oscillators.
