Quonset Hut
A temporary building created in 1941 by Peter Dejongh and Otto Brandenburger and manufactured for the Navy at their facility in Quonset, RI. The ubiquitous buildings were little more than semi-circular steel ribs with corrugated sheet metal attached to them. They were used for everything from troop quarters to supply sheds to airplane hangars. For many years, both Marine Corps Recruit Depots at Parris Island, SC and San Diego, CA used them until more permanent structures could be built. Many Old Corps Marines were trained in quonset huts.
