United States Naval Ordnance Lab
The Naval Ordnance Laboratory (NOL), now disestablished, formerly located in the White Oak area of Montgomery County, Maryland, was the site of considerable work that had practical impact upon world technology. The headquarters of the United States Food and Drug Administration (FDA) now occupies part of the former NOL.
The U.S. Navy Mine Unit, later the Mine Laboratory at the Washington, D.C., Navy Yard, was established in 1918, and the first Officer in Charge (OIC) arrived in February 1919, marking the beginning of the Laboratory. In 1929 the Mine Laboratory was merged with the Experimental Ammunition Station in Indian Head to form the Naval Ordnance Laboratory.
NOL began slowly, and it was not until the beginnings of World War II, when Germany's aircraft-laid magnetic mine began to cause serious problems for the Allies. As the importance of NOL's work became apparent, it also became apparent that there wasn't enough space at the Navy Yard to accommodate the necessary research facilities.
In 1944, acquisition, planning and construction work began at a 712-acre (2.88 km2) wooded site located at 10903 New Hampshire Avenue, Silver Spring, Maryland. Someone remarked to a Navy official during early 1945 that it seemed odd to be building the new laboratory at that time: the war would probably be over before the facility could be finished. "That laboratory" remarked the Navy man, "is not being built for this war".

This 1960s-era postcard image shows the NOL Administration Building and golf course as seen from New Hampshire Ave. After renovation for use by the FDA it still looks much the same, with "Naval Ordnance Laboratory" still carved in stone above the main entrance.
The first technical facilities were in the new magnetic area (the 200 area). This area was in the middle of the woods, and remained so up until the Lab's demise in 1994. It is believed that the area was selected because it was magnetically neutral – there was less iron in the earth than in other areas to interfere with sensitive magnetic experiments. The buildings were made of wood, with wooden pegs instead of nails. The buildings had unusual names: Bldg 203 was the "Spherical Field Lab", Building 204 was the "Long Field Lab".
