Notes:

She is buried as Viola Degruchy, Staley. Last known residence from SSDI, Montclair, Essex, New Jersey. Her father was Canadian and mother English according to the 1930 Census and Viola's occupation was Artist/Painting.
VIOLA DE GRUCHY (Mrs. Mortimer Staley, d. 1986, Montclair, NJ) studied dynamic symmetry with Howard Giles and Bisttram, and in 1930 was teaching a private class in dynamic symmetry at the Master Institute. In 1936, she was given access to some geometrical diagrams drawn by George Henry Felt. Felt ( 1831-1906) was one of the co-founders with Blavatsky of the Theosophical Society in New York in 1875, and had derived a system of geometry based on ancient Egyptian principles. Blavatsky thought they were authentic and discusses them in Isis Unveiled (1877). De Gruchy showed these diagrams to Howard Giles, who then referred her and the drawings to Claude Bragdon, who described his meetings with her to Dorothy Brett in 3 letters dating from 1936. The Felt diagrams derived the golden section and other root rectangles from the circle. The discovery of the Felt diagrams undoubtedly strengthened Giles and Bisttram’s belief in dynamic symmetry as an ancient mystical system based on cosmic principles. De Gruchy provided the illustrations for “The Twin Sisters – Religion and Science,“ the final chapter of James Churchward’s The Sacred Symbols of Mu (1933).
