Few Americans are aware that such an ambitious and comprehensive public housing effort ever took place. Many of the homes are still standing today.

When the U.S. declared war against Germany in April 1917, federal authorities immediately realized that ship, vehicle and arms manufacturing would be at the heart of the war effort. To meet demand, there needed to be sufficient worker housing near shipyards, munitions plants and steel factories.
