A member of our congregation is a former NRC physicist, somewhere within spitting distance of 90. He studied gamma rays, and fissionable material, spending a portion of his career at Chalk River, and another portion on a mountain-top in Colorado. While recounting his career trajectory to me once, he said that when he decided to go into physics, people thought he was foolish. As he put it, chemistry was much more in the public eye at the time, "better living through chemistry" and all that. "What are you going to do with physics?" they would ask. However, after WWII, and the power of theoretical physics was demonstrated, the field became more fashionable. Moreover, as he recounted, there were concerns about the availability of fissionable material, and the cold war fostered worry about whether the West would have as much available to them as the Soviets. So he was always able to persuade sources to fund his research.
In any event, not to digress too much, but I hope one of Prof. Hawkings lasting legacies is that more young people see physics as hip, and worth going into.
