Butenandt, Adolph

The first androgen to be isolated in pure form was androsterone, in 1931, by the chemist Adolph Butenandt, the same guy who isolated the first pheromone (that for the female silkworm moth, bombykol), which we met back in chapter 6. Butenandt managed to isolate 50 mg (less than 0.002 ounces) of androsterone from 25,000 liters of men s urine Some efforts are more heroic than others. 

Here too Adolph Butenandt played a key role. He isolated the first estrogen, estrone, in 1929, in minnte qnantities from the ovaries of 80,000 sows Clearly, Bntenandt was not deterred by major challenges. We have yet to hear the last from him. 

Here is one final triumph for Adolph Butenandt. He was the first to isolate progesterone this in 1934. For his accomplishments, he shared the Nobel Prize for Chemistry in 1939. However, the Nazi regime prevented him from accepting the award. He was finally able to do so in 1949.
