ora Lenore Williams (1865 - Dec. 14, 1937) was a writer and educator known for pioneering new approaches to small-group instruction for children. She founded the A-Zed School and the Institute for Creative Development, later renamed Williams College, in Berkeley, California. Williams had a strong interest in mathematics and philosophy, especially metaphysics, and she published several books centered on metaphysical rumination. Creative Involution (1916) is a response to Henri Bergson's Creative Evolution, which had appeared five years earlier Starting from Bergson's insistence on the fact that "the evolution of life [is] in the double direction of individuality and association", Williams emphasizes the necessity for greater attention to the principle of cohesion or association which Berson termed involution, as a means of moving human society forwards. Reviewers found the book by turns stimulating and puzzling, and more aphoristic than analytical. The Fourth Dimensional Reaches of the Exposition (1915) is an idiosyncratic appreciation of the 1915 Pan-Pacific International Exposition in San Francisco that uses the fourth dimension as a metaphor for the exposition's ability to transport the viewer out of ordinary life. This book includes an early use of the word 'hyperspace' in its modern sense of a portal into another dimension. There are several full-page etchings of exposition sites by the artist Gertrude Partington Albright Less
