At a NIST Colloquium held November 16, 2001 at the National Institute of Standards and Technology, Dr. Ramsey discusses how his 60 year career has taken him all over the world and engaged him in many important events. He was a colleague of scientists such as Hans Bethe, Robert Oppenheimer and Edward Teller on the Manhattan project during WWII. His recollections of great scientists include Albert Einstein, Werner Heisenberg, Niels Bohr, and former NBS Directors Lyman Briggs, Ed Condon, Allen Astin, and Lewis Branscomb.
