I want to know the answer to the following question:
Who developed the method to get epinephrine in it's pure form?
All the background I'm provided with is that "By the 1890s the profound effect of adrenal extracts on many different tissue types had been discovered, setting off a search both for the mechanism of chemical signalling and efforts to exploit these observations for the development of new drugs.". Is that enough to answer the question?
Answer: no
