A German-American biochemist who co-discovered coenzyme A in 1945, the molecule cells use to shuttle the acetyl groups that drive metabolism — a finding so foundational to how biochemistry textbooks explain energy production that it still anchors introductory courses. The work earned him the 1953 Nobel Prize in Physiology or Medicine, shared with Hans Krebs, whose citric acid cycle it directly connects to.
