" Wright's invention did not lead to any further developments, and diamorphine became popular only after it was independently re-synthesized 23 years later by another chemist, Felix Hoffmann.[71] Hoffmann, working at Bayer pharmaceutical company in Elberfeld, Germany, was instructed by his supervisor Heinrich Dreser to acetylate morphine with the objective of producing codeine, a constituent of the opium poppy, pharmacologically similar to morphine but less potent and less addictive. Instead, the experiment produced an acetylated form of morphine one and a half to two times more potent than morphine itself. The head of Bayer's research department reputedly coined the drug's new name, "heroin," based on the German heroisch, which means "heroic, strong" (from the ancient Greek word "heros, ήρως"). Bayer scientists were not the first to make heroin, but their scientists discovered ways to make it, and Bayer led commercialization of heroin.[72]"
