Dr. Ernst Gräfenberg was among the most sought-after gynecologists in pre-World War II Germany. The creator of the first IUD, known as the Gräfenberg ring, he was posthumously credited with identifying the eponymous "Gräfenberg spot" or G-spot. He was also a Jew in Nazi Germany, and by 1938 he had been stripped of his practice, his possessions, and his freedom and was languishing in a Nazi prison.

Kelly Johnson designed the Blackbird, a plane that flew non-stop from London to Los Angeles in less than four hours, outracing the sun and landing four hours before it had taken off, a remarkable feat - and this was more than 35 years ago. Johnson was the innovative genius behind Lockheed's "Skunk Works", and played a leading role in the development of more than forty aircraft, including some of America's most sophisticated planes such as the Constellation, Shooting Star, F-104, U-2, and the SR-71 Blackbird.
