After WWII, it had become clear that the original laboratories located in Washington, D.C., were completely inadequate for the increasingly sensitive experiments NIST scientists were performing. Planners selected a site in the then small, sleepy farming town of Gaithersburg, Md., and ground for the new campus in Gaithersburg was broken in 1961. Major construction was mostly completed by 1970.
