CBS unveiled its Eye Device logo on October 17, 1951. Before that, from the 1940s through 1951, CBS Television used an oval spotlight on the block letters C-B-S. The Eye device was conceived by William Golden based on a Pennsylvania Dutch hex sign as well as a Shaker drawing. (While commonly attributed to Golden, there is speculation that at least some design work on the symbol may have been done by another CBS staff designer, Georg Olden, one of the first African-Americans to achieve some notoriety in the postwar graphic design field.) The Eye device made its broadcasting debut on October 20, 1951. The following season, as Golden prepared a new ident, CBS President Frank Stanton insisted on keeping the Eye device and using it as much as possible.
