Brannock device, 1920s
Charles F. Brannock, Syracuse, New York

Charles F. Brannock (1903-1992) began tinkering with the idea of a new foot-measuring device while still in college. After a trial run on the sales floor of his father’s shoe store, his invention soon gained favor over size sticks because it measured foot length and width at the same time.
