Dr. David L. Bassett, left, and William B. Gruber, inventor of the View-Master, place a jawbone in position to be photographed. The special camera took images from two slightly different angles, producing a seemingly three-dimensional image for the View-Master. More than 1,550 images of human dissections were taken, and the result was the 23-volume Stereoscopic Atlas of Human Anatomy, published in 1962.
