John Jacob Abel to successfully isolate the neutral base of epinephrine by adding ammonium to highly concentrated extract, a method Abel himself tried but failed due to the use of low concentration of extract. After Takamine's success, Abel himself remarked, with great candor, "The efforts of years on my part in this once mysterious field of suprarenal, medullary biochemistry, marred by blunders as they were, eventuated, then, in the isolation of the hormone not in the form of the free base but in that of its monobenzoyl derivative." Together with L.G. Rowntree and B.B. Turner, Abel devised what they called a "vividiffusion" apparatus,
John Jacob Abel Professor of Pharmacology at Columbia University, for help on founding a scientific journal on biochemistry. Together as joint editors, Abel and Herter established the "Journal of Biological Chemistry". The first issue of the journal appeared in 1905. Motivated by the very same goal of trying to create an outlet for a wide dissemination of new scientific findings, he later founded the J"ournal of Pharmacology and Experimental Therapeutics" in 1908. Abel married Mary Hinman in 1883. They met while he was a principal and she was a school teacher in La Porte, Indiana. They had three children, one of whom was
