This Basket weaver's son was not disheartened because of permanent eye damage & rejection in medical school and received nobel!!


Julius Axelrod (May 30, 1912 – December 29, 2004) was an American biochemistHe won a share of the Nobel Prize in Physiology or Medicine in 1970 along with Bernard Katz and Ulf von Euler. The Nobel Committee honored him for his work on the release and reuptake of catecholamine neurotransmitters, a class of chemicals in the brain that include epinephrinenorepinephrine, and, as was later discovered, dopamine. Axelrod also made major contributions to the understanding of the pineal gland and how it is regulated during the sleep-wake cycle.


Axelrod was born in New York City, the son of Jewish immigrants from Poland, Molly (née Leichtling) and Isadore Axelrod, a basket weaver. He received his bachelor's degree in biology from the College of the City of New York in 1933. Axelrod wanted to become a physician, but was rejected from every medical school to which he applied. He worked briefly as a laboratory technician at New York University, then in 1935 he got a job with the New York City Department of Health and Mental Hygiene testing vitamin supplements added to food. He injured his left eye when an ammonia bottle in the lab exploded; he would wear an eyepatch for the rest of his life. While working at the Department of Health, he attended night school and received his master's in sciences degree from New York University in 1941. 


The research experience and mentorship Axelrod received from Brodie at Goldwater Memorial Hospital launched him on his research career. Brodie and Axelrod's research focused on how analgesics (pain-killers) work. During the 1940s, users of non-aspirin analgesics were developing a blood condition known as methemoglobinemia. Axelrod and Brodie discovered that acetanilide, the main ingredient of these pain-killers, was to blame. They found that one of the metabolites also was an analgesic. They recommended that this metabolite, acetaminophen (paracetamol), better known as Tylenol, be used instead.


He examined the mechanisms and effects of caffeine, which led him to an interest in the sympathetic nervous system and its main neurotransmitters, epinephrine and norepinephrine. During this time, Axelrod also conducted research on codeinemorphinemethamphetamine, and ephedrine and performed some of the first experiments on LSDRealizing that he could not advance his career without a PhD, he took a leave of absence from the NIH in 1954 to attend George Washington University Medical School. Allowed to submit some of his previous research toward his degree, he graduated one year later, in 1955. Axelrod then returned to the NIH and began some of the key research of his career. 

Axelrod received his Nobel Prize for his work on the release, reuptake, and storage of the neurotransmitters epinephrine and norepinephrine, also known as adrenaline and noradrenaline.  Some of Axelrod's later research focused on the pineal gland. He and his colleagues showed that the hormone melatonin is generated from tryptophan, as is the neurotransmitter serotonin.  He was elected a Fellow of the American Academy of Arts and Sciences in 1971. He continued to work at the National Institute of Mental Health at the NIH until his death in 2004. Much of his papers and awards are held at the National Library of Medicine.
