This book offers the most extensive collection of Eadweard Muybridge's high-speed photographs capturing human motion. Featuring 4,789 images, it documents 163 actions such as an elderly man lifting, women sweeping, ladder climbing, men boxing, wrestling, and more. Taken at speeds up to 1/6000th of a second, the images detail bone and muscle positions against ruled backgrounds. Subjects are mostly undraped, shown from three angles—front, rear, and three-quarter. Originating from over 100,000 negatives at the University of Pennsylvania, this comprehensive thesaurus remains a vital resource for artists and animators, celebrated for its unparalleled clarity and authenticity.
