From 1945 to 1947, Strong was the site of
non-consensual human experimentation programs under supervision of the
Manhattan Project and its successor, the
United States Atomic Energy Commission. A building adjacent to the hospital and connected to it via tunnel, dubbed the "Manhattan Annex," was constructed in 1943 as a field office for the Manhattan Project. Over a period of two years starting in 1945, a total of seventeen patients admitted to Strong for unrelated ailments were injected with a
plutonium or
uranium solution without their knowledge. The Atomic Energy Commission tracked the patients for the rest of their lives; after their deaths, the Commission exhumed their remains for testing. Surviving patients were later informed of the true nature of the experiments in 1974. ==See also==
