I know of two World War II stories that could be interesting:
1) Hedy Lamarr, claimed by many to be the most beautiful woman ever seen in films, also was a brilliant woman and an inventor. Read about her co-creation of frequency hopping here, as well as her escape from Nazi Germany:
Hedy Lamarr - Wikipedia, the free encyclopedia
2) Jack Benny and George Burns~huge stars at the time, just as they would be in the future~were accused of jewelry smuggling in April 1939. When I compared the dates, I realized that it was near the same date as when the Nazis demanded that Jews begin wearing the yellow star. I have a hunch that they smuggled the gems in order to raise money to help people escape from Nazi Germany. I've tried researching this and didn't come up with anything; however, I still feel that this was the reason for what they did.

b)
