Cindy Kelly: I'm Cindy Kelly, Atomic Heritage Foundation. I am in Hastings-on-Hudson, New York. It is Friday, May 11, 2018. I have with me Spencer Weart. My first question is to ask him to say his name and spell it.
Spencer Weart: I am Spencer Weart, W-E-A-R-T, like heart.
Kelly: Great. Spencer, you are a physicist. You had an early career in science. Tell us about your childhood and a little bit about how you became interested in science and science history.
