Luis Federico Leloir
Luis Federico Leloir (September 6, 1906 – December 2, 1987) was an Argentine physician and biochemist who received the 1970 Nobel Prize in Chemistry for his discovery of the metabolic pathways by which carbohydrates are synthesized and converted into energy in the body. Although born in France, Leloir received the majority of his education at the University of Buenos Aires and was director of the private research group Fundación Instituto Campomar until his death in 1987. His research into sugar nucleotides, carbohydrate metabolism, and renal hypertension garnered international attention and led to significant progress in understanding, diagnosing and treating the congenital disease galactosemia. Luis Leloir is buried in La Recoleta Cemetery, Buenos Aires. Biography Early years Leloir's parents, Federico Augusto Rufino Leloir Bernal and Hortensia Aguirre de Leloir, traveled from Buenos Aires to Paris in the middle of 1906 with the intention of treating Federico's illness. However, Federico died in late August, and a week later Luis was born in an old house at 81 Víctor Hugo Road in Paris, a few blocks away from the Arc de Triomphe. After returning to Argentina in 1908, Leloir lived together with his eight siblings on their family's extensive property El Tuyú that his grandparents had purchased after their immigration from the Basque Country of northern Spain: El Tuyú comprises 400 km2 of sandy land along the coastline from San Clemente del Tuyú to Mar de Ajó which has since become a popular tourist attraction. During his childhood, the future Nobel Prize winner found himself observing natural phenomena with particular interest; his schoolwork and readings highlighted the connections between the natural sciences and biology. His education was divided between Escuela General San Martín (primary school), Colegio Lacordaire (secondary school), and for a few months at Beaumont College in England. His grades were unspectacular, and his first stint in college ended quickly when he abandoned his architectural studies that he had begun in Paris' . It was during the 1920s that Leloir invented salsa golf (golf sauce). After being served prawns with the usual sauce during lunch with a group of friends at the Ocean Club in Mar del Plata, Leloir came up with a peculiar combination of ketchup and mayonnaise to spice up his meal. With the financial difficulties that later plagued Leloir's laboratories and research, he would joke, "If I had patented that sauce, we'd have a lot more money for research right now." Career Buenos Aires After returning again to Argentina, Leloir obtained his Argentine citizenship and joined the Department of Medicine at the University of Buenos Aires in hopes of receiving his doctorate. However, he got off to a rocky start, requiring four attempts to pass his anatomy exam. He finally received his diploma in 1932 and began his residency in the Hospital de Clínicas and his medical internship in Ramos Mejía hospital. After some initial conflicts with colleagues and complications in his method of treating patients, Leloir decided to dedicate himself to research in the laboratory, claiming that "we
