I want to know the answer to the following question:
Who received the Nobel Prize in Medicine in 1939?
All the background I'm provided with is that "Ehrlich’s approach of systematically varying the chemical structure of synthetic compounds and measuring the effects of these changes on biological activity was pursued broadly by industrial scientists, including Bayer scientists Josef Klarer, Fritz Mietzsch, and Gerhard Domagk.". Is that enough to answer the question?
Answer: yes
