Severo Ochoa

Ochoa was born in Luarca (Asturias), Spain. His father was Severo Manuel Ochoa (who he was named after), a lawyer and businessman, and his mother was Carmen de Albornoz. Ochoa was the nephew of Álvaro de Albornoz (President of the Second Spanish Republic in exile and former Foreign Minister), and a cousin of the poet and critic Aurora de Albornoz. His father died when Ochoa was seven, and he and his mother moved to Málaga, where he attended elementary school through high school. His interest in biology was stimulated by the publications of the Spanish neurologist and Nobel laureate Santiago Ramón y Cajal. In 1923, he went to the University of Madrid Medical School, where he hoped to work with Ramón y Cajal, but Ramón y Cajal retired. He studied with father Pedro Arrupe, and Juan Negrín was his teacher: marking the beginning of Ochoa's biochemistry career. Ochoa completed his undergraduate medical degree in the summer of 1929 and decide to go abroad again to gain further research experience. His creatine and creatinine work led to an invitation to join Otto Meyerhof's laboratory at the Kaiser Wilhelm Institute for Biology in Berlin-Dahlem in 1929. At that time the institute was a "hot bed" of the rapidly evolving discipline of biochemistry, and thus Ochoa had the experience of meeting and interacting with scientists such as Otto Heinrich Warburg, Carl Neuberg, Einar Lundsgaard, and Fritz Lipmann in addition to Meyerhof who had received the Nobel Prize in Physiology and Medicine less than a decade earlier. In 1930 Ochoa returned to Madrid to complete research for his MD thesis, which he defended that year. In 1931, a newly minted MD, he married Carmen García Cobián. They did not have any children. He then began postdoctoral study at the National Institute for Medical Research in London, where he worked with Henry Hallett Dale. His London research involved the enzyme glyoxalase and was an important departure in Ochoa's career in two respects. First, the work marked the beginning of Ochoa's lifelong interest in enzymes. Second, the project was at the cutting edge of the rapidly evolving study of intermediary metabolism. ==Career and research==

In 1933 the Ochoas returned to Madrid where he began to study glycolysis in heart muscle. Within two years, he was offered the directorship of the Physiology Section in a newly created Institute for Medical Research at the University of Madrid Medical School. Unfortunately the appointment was made just as the Spanish Civil War erupted. Ochoa decided that trying to perform research in such an environment would destroy forever his "chances of becoming a scientist." Thus, "after much thought, my wife and I decided to leave Spain." In September 1936 they began what he later called the "wander years" as they traveled from Spain to Germany, to England, and ultimately to the United States within a span of four years. Ochoa left Spain and returned to Meyerhof's Kaiser Wilhelm Institute for Biology now relocated in Heidelberg, where Ochoa found a profoundly changed research focus. During his 1930 visit the laboratory work was "classical physiology," which Ochoa described as "one could see muscles twitching everywhere". In 1942 he was appointed research associate in medicine at the New York University School of Medicine and there subsequently became assistant professor of biochemistry (1945), professor of pharmacology (1946), professor of biochemistry (1954), and chair of the department of biochemistry. In 1956, he became an American citizen. Ochoa continued research on protein synthesis and replication of RNA viruses until 1985, when he returned to now democratic Spain where he was a science advisor. Ochoa was also a recipient of U.S. National Medal of Science in 1978. Severo Ochoa died in Madrid, Spain on 1 November 1993. Carmen García Cobián had died in 1986. Long after his death, Spanish actress Sara Montiel claimed that she and Severo Ochoa were involved in a romantic relationship in the 1950s, as stated in an interview in Spanish newspaper El País: "The great love of my life was Severo Ochoa. But it was an impossible love. Clandestine. He was married, and besides, him doing research and me doing films wasn't a good match." Legacy A research center that was planned in the 1970s was opened in 1975 (CBM) in the Autonomous University of Madrid (UAM). After his death, it was named the Centro de Biología Molecular Severo Ochoa. In Leganés, Madrid, a hospital bears his name, as does the Madrid Metro station serving it, Hospital Severo Ochoa. The asteroid 117435 Severochoa is also named in his honor. In 2003, the Spanish General Post Office (Correos) issued a €0,76 postage stamp honoring Ochoa, as one of a pair featuring Spanish medical Nobel Prize winners alongside Santiago Ramón y Cajal. In June 2011, the United States Postal Service issued a stamp honoring him, as part of the American Scientists collection, along with Melvin Calvin, Asa Gray, and Maria Goeppert-Mayer. This was the third volume in the series. The main road in to the tourist resort Benidorm is named Avenida Dr. Severo Ochoa in his honor. ==References==
