Forget about Thor and Iron Man. History is full of real superheroes, like the bow-tied young men known as the Poison Squad.
What was their feat? For five long years, starting in 1902, they sat down to meals “laced with increasing amounts of suspected poisons”—all in the name of making food safer for you and me.
Their efforts led to what’s now known as the Food and Drug Administration (FDA). Atlas Obscura has photos and the rest of the Poison Squad‘s fascinating tale.
