was an Alsos Mission Allied unit formed to investigate Axis scientific developments, especially nuclear, chemical and biological weapons, as part of the Manhattan Project during World War II. Colonel Boris Pash, a former Manhattan Project security officer, was the mission's commander, and Samuel Goudsmit was its scientific leader.
