Joan Hinton was a physics graduate student at the University of Wisconsin when she was tapped for Los Alamos. She worked on a team building the first reactor able to use enriched uranium as fuel. Hinton also witnessed the Trinity Test. Just weeks after the US dropped atomic bombs on Hiroshima and Nagaski, killing more than 200,000 people, Hinton drove physicist Harry Daghlian to the hospital after he was exposed to a lethal amount of radiation from a plutonium core. He died about three weeks later.
