I wouldn't really call this a trophy. They are historically significant people no matter how you feel about them, and this is a pretty tasteful way to represent that significance - just a simple signature in a topical book from their time. I also think it's a bit strange to single out the crew. They are not any more responsible (and arguably less responsible) than the physicists and bureaucrats represented here who designed and built the bomb explicitly for the purpose of dropping it on Japan.
