In 1945, the FBI raided a warehouse in Los Angeles that was used for storage by the German Consulate. Among the files, they found a collection of 3×5-inch cards kept by the Nazi regime containing contact information for important people in LA. The cards included the names, addresses, and phone numbers of people in the entertainment industry, academia, and industry. And it serves as a terrifying reminder that the normalization of the Nazis in the 1930s provided cover for some very powerful people in the US to be friendly with genocidal maniacs.
I obtained a five-page document that contains the information from the cards as part of a Freedom of Information Act request to the FBI. I had previously requested all FBI documents on Norman Chandler, the former publisher of the LA Times who, it turns out, was hanging out with Nazis in the late 1930s. And now the National Archives has provided me with this document as part of that request.
The list doesn’t explicitly say that everyone on the list was working closely with the Nazis. But judging by what we know about some of the associations of those on the list, this was at the very least people who might be invited to a Nazi cocktail party. And at worst, people who were actively working with the Nazis and keeping in regular contact.
