The 1963 Nobel Prize in Physiology or Medicine, awarded to physiologist Alan Lloyd Hodgkin for establishing the propagation mechanism of nerve impulses called action potentials -- consequently helping to understand the mechanism behind disorders such as multiple sclerosis, seizures and Parkinson's disease. Hodgkin is also responsible for identifying the Hodgkin Cycle and, along with colleagues Andrew Fielding Huxley and John Carew Eccles, hypothesized the existence of ion channels on cell membranes, a concept which took over 20 years to confirm; that confirmation earned Erwin Neher and Bert Sakmann the 1991 Nobel Prize. This Nobel Prize medal is made of 23k gold and features the relief portrait of Alfred Nobel, with his name and the years of his birth and death. Verso features the words, ''INVENTAS VITAM JUVAT EXCOLUISSE PER ARTES'', which translates from Latin to, ''Inventions enhance life which is beautified through art''. A.L. Hodgkin's name and the year 1963 in Roman numerals are engraved on a plaque below the relief, framed by the words, ''REG. UNIVERSITAS MED-CHIR-CAROL''. On the right side is the name ''E LINDBERG'', who designed the prize. Comes with 6 original photographs of Hodgkin (at least 4 of which are from the ceremony in Oslo on 10 December 1963), a New York Times article on Hodgkin dated 18 October 1963, a portion of a 1976 issue of ''The Journal of Physiology'' featuring an essay by Hodgkin, and the official 1963 English edition of the Nobel Prize publication, featuring Hodgkin and partner Huxley on the cover. Medal is housed in the maroon leather presentation box with a white satin lining and Hodgkin's name printed on the front. Box measures 5.5'' x 5.5'' x 1''. Medal measures 6.5 cm or 2.56'' in diameter, and weighs 196 g or 6.9 oz, consistent with the original Nobel Prizes awarded in 1963. Presented in near fine condition. With an LOA from the daughter of Dr. Alan Hodgkin.
