🇸🇪 Sweden

Carl Wilhelm Scheele discovered oxygen, chlorine, and more elements than almost anyone in the eighteenth century. Working alone in Swedish pharmacies, he identified each substance by tasting it. Mercury compounds. Arsenic. Hydrogen cyanide, which he found pleasantly sharp. His hands swelled. His joints ached. His body filled with what he'd catalogued. He died at forty-three, notebooks open, descriptions precise. The poisons tasted exactly as he said they would.
