Anne Frank. Wikipedia image.

On this date seventy-five years ago, June 15, 1943, Anne Frank noted in her diary that everyone in Holland had been directed to turn in their radios.  She noted that throughout Holland, people were scrambling to find old radios to turn in so that they could keep another set, and that those in her group had arranged to get a small secret set.

As we have written previously, some ingenious examples of clandestine Dutch receivers are shown above.
