New York City: The Psychological Corporation, circa 1950s. Two-dimensional wooden puzzle. Housed in original green cardboard box measuring 4 x 6.5 inches, printed in silver with manufacturer’s information and a capital letter M.
Early example of the Wechsler Intelligence Scale for Children Object Assembly Test, devised by Bellevue psychologist David Wechsler in 1949 as part of a wide-ranging assessment to measure intelligence in children. There were four different WISC Object Assembly Tests, each identified by a capital letter on the box: A for automobile, F for face, H for horse, and M for mannequin. (Wechsler also designed a series of Object Assembly Tests for adults as part of the Wechsler-Bellevue Intelligence Test.) Modernized versions of the original WISC puzzles are still in diagnostic use today. Classic example of midcentury modern design, at the intersection of science and art.
