Eighty years ago, President Franklin D. Roosevelt lifted the immigration quotas for the only time during World War II and allowed almost 1,000 European refugees to enter the United States.

The 982 men, women and children—874 of them Jewish—were housed behind barbed wire in Fort Ontario in Oswego, N.Y., about 40 miles north of Syracuse. They remained there for 18 months until Roosevelt’s successor, Harry S. Truman, allowed them to become American citizens after first crossing into Canada and then returning to the United States.

Now legislation has been reintroduced in Congress to designate their temporary home as the Fort Ontario Holocaust Refugee Shelter National Historical Park.

“The Holocaust Refugee Shelter at Fort Ontario was a place of safety and hope during a dark moment in history, and it deserves recognition in the National Park System,” the bill’s chief Senate sponsor, Sen. Kirsten Gillibrand (D-N.Y.), said in a recent press release announcing the bill, which passed the Senate in the last Congress but was never considered in the U.S. House of Representatives.

A museum telling the story about the refugees sits in the old Fort Ontario administration building. The site itself first housed a British fort during the French and Indian War and was the scene of battles during the American Revolution and the War of 1812.
