Pugwash founder and former President Joseph Rotblat is featured on the GiANT Impact website for global business leaders, as a leader who "finished strong" and who had a powerful vision to fulfill. So true. He worked tirelessly to the end of his days to try to create conditions for a world without nuclear weapons.
I found this site cheering on a day when the New York Times has run a story (available here) about the Obama Administration's revision to guidance on what people should do in the event of a nuclear explosion. Rotblat, when asked what one should do in the event of a nuclear explosion, famously said, "Run toward it."
Here is a photo of Prof at the 1999 Student Pugwash USA 20th anniversary international conference. In the later years of his life he prioritized speaking with student and young people.
