The same legislation scheduled a further increase to $1.25 in September 1963. Dad described how the DuPont Company at that point decided to automate elevators in its office building in Wilmington, Delaware. The old elevators worked fine, but required an operator. Within a short time, all the elevators were automated and the operators of the old ones had no jobs."
