Légende
Physician and physical anthropologist William Montague Cobb (1904-1990) was the first African-American Ph.D in anthropology. He was also involved in civil rights activism. This is a spreading metal caliper with curved, rounded ends. There is a crossbar scale that slides as the rounded ends get farther apart. The small circular screw that holds the scale in place has become detached.
