143pp, Dover, New York, 1971 "The Human Machine" by George B. Bridgman (1865-1943), a Canadian painter and instructor at the Art Students League. The original was published in 1939 by Bridgman Publishers, Inc. under the title "THE HUMAN MACHINE THE ANATOMICAL STRUCTURE & MECHANISM OF THE HUMAN BODY." This book is one of Bridgman's later works and represents a culmination of his Bridgman-style art anatomy, which simplifies the musculoskeletal system to understand its structure. Applying simple forms like rectangular prisms and circles to the human body can be seen in the works of Dürer and Martinez, and is a highly universal practice in art. Bridgman's innovation was to apply this to anatomical structure and its movement, and to teach it to his students. This method provides a key for students who have few opportunities to touch anatomical specimens to grasp the forms of the internal structure.
