This is the largest selection ever made from the famous Muybridge sequence high-speed photographs of human motion. Containing 4,789 photographs, it illustrates some 163 different types of action: elderly man lifting log, woman sweeping, woman climbing ladder, men boxing and wrestling, child crawling, man lifting weight, man jumping, and 155 other types of action, some of which are illustrated by as many as 62 different photographs. Taken at speeds ranging up to 1/6000th of a second, these photographs show bone and muscle positions against ruled backgrounds. Almost all subjects are undraped, and all actions are shown from three angles: front, rear, and three-quarter view. These historic photographs, one of the great monuments of nineteenth-century photography, are reproduced original size, with all the clarity and detail of the originals. As a complete thesaurus of human action, it has never been superseded. Muybridge was a genius of photography, who had unlimited financial, technical, and scientific backing at the University of Pennsylvania. This volume presents the final selection from more than 100,000 negatives made at an expenditure of more than $50,000. It has never been superseded as a sourcebook for artists, students, animators, and art directors.
