In 1953, while working a hotel switchboard, a college graduate named Shea Zellweger began a journey of wonder and obsession that would eventually lead to the invention of a radically new notation for logic. From a basement in Ohio, guided literally by his dreams and his innate love of pattern, Zellweger developed an extraordinary visual system - called the “Logic Alphabet” - in which a group of specially designed letter-shapes can be manipulated like puzzles to reveal the geometrical patterns underpinning logic. Indeed, Zellweger has built a series of physical models of his alphabet that recall the educational teaching toys, or “gifts,” of Friedrich Froebel, the great nineteenth century founder of the Kindergarten movement.
