Title: John Jacob Abel
Content: John Jacob Abel John Jacob Abel (19 May 1857 – 26 May 1938) was an American biochemist and pharmacologist. He established the pharmacology department at Johns Hopkins University School of Medicine in 1893, and then became America's first full-time professor of pharmacology. During his time at Hopkins, he made several important medical advancements, especially in the field of hormone extraction. In addition to his laboratory work, he founded several significant scientific journals such as the "Journal of Biological Chemistry" and the "Journal of Pharmacology and Experimental Therapeutics". John Jacob Abel was born in 1857 to George M. and Mary (Becker)

Ever since his early years in Europe, Abel showed great interest in isolating pure form of internal gland hormones. The first work that led to his international reputation as a pharmacologist and biochemist was the isolation of epinephrine from adrenal medulla. However, he was only able to isolate a monobenzoyl derivative of epinephrine. While he was improving his processes on decomposing the benzoyl derivative to obtain salts of epinephrine using saponification, a Japanese chemist J. Takamine, who had visited his lab, was able

Content: time on proteins—proteins were considered as unlikely to have such highly specific physiological activity shown by a hormone such as insulin. In 1927, he was published in the journal Science for this work with a paper entitled "Chemistry in Relation to Biology and Medicine with Especial Reference to Insulin and Other Hormones". At the time, Abel's laboratory was no doubt the center of insulin research in the United States. A lot of young scientists came to his lab and worked under Abel to study the newly crystallized hormone. Abel himself gradually withdrew from the actual experimental work on insulin after

Content: the first four years, but he continued to guide the scientists in his lab to unravel more and more about the structure of insulin molecule. Despite his great dedication to experimentation work, Abel's historical significance is certainly not restricted to his research work. He was also the founder of a number of influential scientific journals. As more and more research was conducted in the field of biochemistry, Abel realized the importance of having a platform that allowed scientists all around the world to publish their work and report on their findings. He therefore asked his friend Dr. C. A. Herter,

Mary Abel and John Abel both passed in 1938; Mary in January and John in May due to a coronary thrombosis.
