In 1952, some sources say - apparently incorrectly - that the first time a pedestrian "Don't Walk" sign was installed in America, it was on this day, in New York City. Others cite the date as 29 Feb 1952. However, much earlier examples have been discussed in an article on the Highway History page of the U.S. Department of Transportation web site. This article has found examples of “Don't Walk” signs dating from the late 1930's.
