Edward Teller Left Mark on Science, Society (washingtonpost.com)

An amazing man who was a brilliant mind, too. I think he is best summed up in the following:

In Teller's autobiography "Memoirs: A Twentieth-Century Journey in Science and Politics," Teller said he was often asked whether he regretted having worked on the atomic and hydrogen bombs.

"My answer is no. I deeply regret the deaths and injuries that resulted from the atomic bombings, but my best explanation of why I do not regret working on weapons is a question: What if we hadn't?"
