Luis Federico Leloir was an Argentinean physician and biochemist who won the Noble Prize for Chemistry for finding out the processes which convert carbohydrates into energy in the body. He was born in France but moved to Argentina with his family when he was only two-year-old. He started his research work on the role of adrenalin on the metabolism of carbohydrates and the effects of fatty acids when oxidized. Later on he worked on the process in which carbohydrate entering the body was broken down by nucleotides to produce sugar which was stored in the body and then converted into energy. He proved to the world that true scientific research on an international level could be carried out in a third-world and underdeveloped country even when the country is gripped with political unrest. Lenoir was also a good craftsman which helped him build equipments required for carrying out his experiments. Funds for research in Argentina were not readily available at that time. In times of distress Leloir’s expertise in making his own equipment helped him tide over difficulties faced due to the unavailability of proper tools allowing him to continue with his work without any hindrance.
Childhood & Early Life
Luis Federico Leloir was born in Paris, France, on September 6, 1906 where his parents had come for medical treatment. His father, Federico Leloir was a non-practicing lawyer and his mother was Hortensia Aguirre de Leloir.
He returned to Argentina with his mother after his father died in Paris.
He did his initial schooling from the ‘Escuela General San Martin’ primary school, the ‘Colegio Lacordaire’ secondary school and finally the ‘Beumont College, England’ where he studied only for a few months.
He studied architecture for some time at the ‘Ecloe Polytechnique’ in Paris but had to abandon his studies due to poor grades.
He joined the ‘Department of Medicine’ at the University of Buenos Aires’ after returning to Argentina. He received his degree in medicine in 1932 and did his internship at the ‘Ramos Mejia Hospital’ in Buenos Aires from 1932 to 1934.

Luis Federico Leloir joined the ‘Institute of Physiology’ under the ‘University of Buenos Aires’ as a research assistant and worked there with Bernardo A. Houssay on the role played by adrenalin on carbohydrate metabolism from 1934 to 1935.
He moved to the UK in 1936 and worked for one year at the ‘Biochemical Laboratory’ of ‘Sir Frederick Gowland Hopkins Hospital’ under the ‘University of Cambridge’.
He returned to Argentina in 1937 and completed his doctoral work on the effect of the adrenal glands on carbohydrate metabolism.
He moved to the United States in 1943 due to political unrest in Argentina and joined the department of pharmacology at the ‘Washington University School of Medicine’ in St. Louis. While there, he worked with Carl F. and Gerty T. Cori at the ‘Cori’s Laboratory’ located in St. Louis.
In 1944 he joined the ‘College of Physicians and Surgeons’ under the ‘University of Columbia’ in New York as a research assistant and worked with D. E. Green.
He returned to Argentina in 1945 to work under Houssay again at the ‘Institut de Investigaciones Bioquimicas de la Fundacion Campomar’ or the ‘Campomar Biochemical Research Institute’ in Buenos Aires. In 1947 he was appointed the Director of the institute. Despite meager funding he started research on the formation and breakdown of lactose in the body which led to the discovery of nucleotides which help to store sugar in the body during the biosynthesis of carbohydrates.
By 1947 he had built up a team of scientists which included Raul Trucco, Alejandro Paldini, Enrico Cabib and others who helped him find out the reasons of hypertension due to a malfunctioning kidney.
He and his team discovered the sugar nucleotides responsible for the metabolism of carbohydrates in the beginning of 1948 and later the primary mechanisms of galactose metabolism, presently known as ‘Leloir pathway’, which caused ‘galactesemia’.
When Jaime Campomar, the industrialist who had funded the Institute, died in 1956, the research work came to a halt due to lack of funds. Leloir arranged for funds from the ‘National Institute of Health’ in the United States to keep the research at the institute going.
