[RJS1950]

There was a group at Los Alamos who were working on how to handle and separate the plutonium to prevent a critical mass. The reaction got out of hand and he was poisoned. His name was Haroutune Krikor Daghlian, Jr.

The second was Louis Alexander Slotin who received a lethal dose of radiation in 1946, after the war.
