Mario Capecchi
Mario Ramberg Capecchi (6 October 1937) is an Italian-born molecular geneticist and a co-awardee of the 2007 Nobel Prize in Physiology or Medicine for discovering a method to create mice in which a specific gene is turned off, known as knockout mice. He shared the prize with Martin Evans and Oliver Smithies. He is currently Distinguished Professor of Human Genetics and Biology at the University of Utah School of Medicine. Life. Mario Capecchi was born in Verona, Italy, as the only child of Luciano Capecchi and Lucy Ramberg, an Italian-born daughter of American-born Impressionist  painter Lucy Dodd Ramberg and German archaeologist Walter Ramberg. His parents weren't married, and due to the chaos in Europe caused by World War II, the story of his early life is remarkable, but the details are unclear. In 1941 he and his mother were living near Bolzano, about 160 miles north of his father in Reggio Emilia when his mother was arrested and deported for pamphleteering and belonging to an anti-Fascist group. Prior to her arrest she had made contingency plans by selling her belongings and giving the proceeds to a nearby peasant family to care for  her child. However, it was not long before Mario ended up on the streets of Bolzano. In July 1942, a few months before his fifth birthday, Italian records suggest he was reunited with his father in Reggio Emilia, which Mario did confirm but stated that he stayed with his father for only for a few brief periods and that he mostly lived on the streets until he was placed in an orphanage towards the end of the war. Mario almost died of malnutrition. His mother survived the war in Germany (part of the reason the details of his early life  are unclear is that she would never talk about her experiences), and when it ended she began a year-long search for him. She finally found him on his ninth birthday in a hospital bed in Reggio Emilia ill with a fever and subsisting on a daily bowl of chicory coffee and bread crust. She took him to Rome, where he had his first bath since he had left her care and where, with money sent by his uncle, Edward Ramberg, an American physicist at RCA, they made arrangements to depart to the United States. He and his mother moved  to Pennsylvania to live at an "intentionally cooperative community" called Bryn Gweled, which had been co-founded by his uncle. (Capecchi's other maternal uncle, Walter Ramberg, was also a prominent American physicist). He graduated from George School, a Quaker boarding school in Bucks County, Pennsylvania, in 1956. Capecchi received his Bachelor of Science in chemistry and physics in 1961 from Antioch College in Ohio. Capecchi came to MIT as a graduate student intending to study physics and mathematics, but during the course of his studies, he became interested in molecular biology. He subsequently transferred to Harvard to join the  lab of James D. Watson, co-discoverer of the structure of DNA. Capecchi received his Ph.D. in biophysics in 1967 from Harvard University, with his doctoral thesis completed under the tutelage of Watson. Capecchi was a Junior Fellow of the Society of Fellows at Harvard University from 1967 to 1969. In 1969 he became an assistant professor in the Department of Biochemistry at Harvard Medical School. He was promoted to associate professor in 1971. In 1973 he joined the faculty at the University of Utah. Since 1988 Capecchi has also been an investigator of the Howard Hughes Medical Institute. He  is a member of the National Academy of Sciences. He has given a talk for Duke University's Program in Genetics and Genomics as part of their Distinguished Lecturer Series. He was the speaker for the 2010 Racker Lectures in Biology & Medicine and Cornell Distinguished Lecture in Cell and Molecular Biology at Cornell University. He is a member of the Italy-USA Foundation. After the Nobel committee publicly announced that Capecchi was awarded the Nobel prize, an Austrian woman named Marlene Bonelli claimed that Capecchi was her long-lost half-brother. In May 2008, Capecchi met with Bonelli, 69, in  northern Italy, and confirmed that she was his sister. Knockout mice. Capecchi was awarded the Nobel prize for creating a knockout mouse. This is a mouse, created by genetic engineering and in vitro fertilization, in which a particular gene has been turned off. For this work, Capecchi was awarded the 2007 Nobel prize for medicine or physiology, along with Martin Evans and Oliver Smithies, who also contributed. Capecchi has also pursued a systematic analysis of the mouse Hox gene family. This gene family plays a key role in the control of embryonic development in all multicellular animals. They determine the  placement of cellular development in the proper order along the axis of the body from head to toe.
