Last month, 60 Minutes aired an interview with Sir Nicholas Winton, the London-born son of German Jews who has become known in England as “the British Schindler” for his efforts to rescue hundreds of Czech children, most of them Jews.In the course of the segment, Winton mentioned that in 1939, he wrote a letter to President Roosevelt, asking the United States to accept some of the children. “But the Americans wouldn’t take any, which was a pity,” Winton told Bob Simon. “We could’ve got a lot more out.”Neither family members nor scholars who have researched Winton’s story have ever been able to locate a copy of that letter—but after the 60 Minutes segment, a National Archives staff member named David Langbart began digging through the files until he found it. Earlier this week, on the occasion of Winton’s 105th birthday, Langbart presented him with both the original missive and the Roosevelt Administration’s response.“Perhaps people in America do not realize how little is being done and has been done for refugee children in Czechoslovakia,” Winton wrote. “[T]here are thousands of children, some homeless and starving, mostly without nationality, but they certainly all have one thing in common: there is no future, if they are forced to remain where they are.” Winton went on to describe their destitution, and closed with the question, “Is it possible for anything to be done to help us with this problem in America?”The answer was a firm “no.” The White House handed the letter off to the State Department, which in turn instructed the U.S. Embassy in London to inform Winton that “the United States Government is unable…to permit immigration in excess of that provided for by existing immigration laws.”Indeed, 1939 was the one year out of Roosevelt’s 12 in office that he permitted the full use of the immigration quotas for Germany and other European countries with large Jewish populations. But the law was the law; there was no more room. “The United States opened its doors to the extent that the law allowed at the time,” Langbart, the National Archives staffer, told CBS. “I wish it could have been more—but it wasn’t.”But the truth is, it could easily have been.The very same week that Winton wrote to Roosevelt, the refugee ship St. Louis was making its way across the Atlantic with its 937 German Jewish passengers all dreaming of freedom. Soon they would be refused admission to Cuba and the United States, and forced to return to Europe, where many would later be murdered by the Nazis.But in 1938, after the Kristallnacht pogroms, the governor of the U.S. Virgin Islands, Lawrence Cramer, backed by the territory’s legislative assembly, publicly offered to accept Jewish refugees fleeing the Third Reich. “The U.S. immigration quotas did not apply to our territory,” Rep. Donna Christensen, a Democrat who currently represents the Virgin Islands, told me last month. “So refugees could have been admitted on a temporary basis, on tourist visas, for as long as they were in danger.”Secretary of the Interior Harold Ickes supported the proposal, but the State Department strongly opposed it. Roosevelt sided with State, vetoing the plan on the grounds that Nazi spies might disguise themselves as Jewish refugees and sneak into the mainland U.S. via the islands. In fact, no cases of Nazis posing as refugees to get into America were ever discovered.But there were other ways that Jews could have been admitted despite the rigorous quotas. Henry Feingold, a professor emeritus of history at Baruch College and one of the leading experts on the 1930s refugee crisis, noted that the law permitted the non-quota immigration of an unrestricted number of “ministers, their wives, and unmarried children.” The term “ministers” included rabbis. “In other words, quite a few rabbis and their families could have been admitted in 1939 despite the quota being filled that year with regular immigration from Germany and other European countries,” Feingold said.As it happens, Feingold—then a child—was among the lucky handful who qualified under the immigration quotas and were able to reach the United States. He left Germany with his family just days before Kristallnacht. Most of his extended family stayed behind in Europe, and nearly all of his aunts, uncles, cousins and grandparents were killed in the Holocaust.Stephen Norwood, a professor at the University of Oklahoma who has researched relations between American and German universities in the 1930s, points to two additional categories that could have been used to admit Jews outside the quota system. “A small number of college professors and students were admitted on a non-quota basis, provided an American college hired the professors and contributors, usually from the Jewish community, covered the students’ expenses,” he explained. “But many others could have immigrated to the U.S. within the law, if the administration hadn’t been looking for every possible way to keep immigrants out.”In his recent book The Third Reich in the Ivory Tower, Norwood noted at least 50 instances in which American colleges offered scholarships to European Jewish refugee students, but the Roosevelt administration blocked their entry. U.S. officials claimed the students could not prove they had a safe address in Europe to which they could later return–and thus constituted a “risk” to become “financially dependent” on the federal government.Another option for Jewish refugees was British Mandatory Palestine. Ironically, Winton’s letter to FDR was written just day after the British announced their new White Paper policy, shutting off the Holy Land to all but a trickle of Jewish immigration. Could FDR have dissuaded London from taking that step? “England desperately needed American support because it knew war with Germany was likely,” noted Monty Penkower, a professor emeritus of Jewish history at the Machon Lander Graduate Center of Jewish Studies in Jerusalem and the author of the new book Palestine in Turmoil: The Struggle for Sovereignty, 1933-1939. “Had FDR put a little behind-the-scenes pressure on the British to keep Palestine more widely open to Jewish refugees, they might have listened.”Which brings us back to Winton, whose parents had changed their name from Wertheim and converted to Christianity after arriving in London. A stockbroker by profession, he got into refugee work after the Kristallnacht pogrom, spurred on by friends who shared his outrage over events in Germany. Eventually, he managed to arrange for the transport of 669 Czech children, finding families to take them in. One final group of 250 children were scheduled to depart from Prague on Sept. 1, 1939—but they were trapped when the Germans invaded Poland that day, and all of them were eventually murdered in the Holocaust.His letter to the president of the United States, written six months earlier, in May 1939, remains a tragic reminder of the desperation not just of Jews trying to flee Hitler, but of those working so hard to save them. And the Roosevelt Administration’s response remains a symbol of a government that looked for every reason to say “no” to Jewish refugees, even when the law itself offered numerous options to save lives by opening the doors just a little.
