IN: Claude Levi-Strauss (English: ; French: [klod levi stRos]; 28 November 1908, Brussels - 30 October 2009, Paris) was a French anthropologist and ethnologist whose work was key in the development of the theory of structuralism and structural anthropology. He held the chair of Social Anthropology at the College de France between 1959 and 1982 and was elected a member of the Academie francaise in 1973. He received numerous honors from universities and institutions throughout the world and has been called, alongside James George Frazer and Franz Boas, the "father of modern anthropology". Levi-Strauss argued that the "savage" mind had the same structures as the "civilized" mind and that human characteristics are the same everywhere.

Claude Levi-Strauss was born to French Jewish parents who were living in Brussels at the time, where his father was working as a portrait painter. He grew up in Paris, living on a street of the upscale 16th arrondissement named after the artist Claude Lorrain, whose work he admired and later wrote about. During the First World War, he lived with his maternal grandfather, who was the rabbi of the synagogue of Versailles. He attended the Lycee Janson de Sailly and the Lycee Condorcet. At the Sorbonne in Paris, Levi-Strauss studied law and philosophy. He did not pursue his study of law, but passed the agregation in philosophy in 1931. In 1935, after a few years of secondary-school teaching, he took up a last-minute offer to be part of a French cultural mission to Brazil in which he would serve as a visiting professor of sociology at the University of Sao Paulo while his then wife, Dina, served as a visiting professor of ethnology. The couple lived and did their anthropological work in Brazil from 1935 to 1939. During this time, while he was a visiting professor of sociology, Claude undertook his only ethnographic fieldwork. He accompanied Dina, a trained ethnographer in her own right, who was also a visiting professor at the University of Sao Paulo, where they conducted research forays into the Mato Grosso and the Amazon Rainforest. They first studied the Guaycuru and Bororo Indian tribes, staying among them for a few days. In 1938, they returned for a second, more than half-year-long expedition to study the Nambikwara and Tupi-Kawahib societies. At this time, his wife suffered an eye infection that prevented her from completing the study, which he concluded. This experience cemented Levi-Strauss's professional identity as an anthropologist. Edmund Leach suggests, from Levi-Strauss's own accounts in Tristes Tropiques, that he could not have spent more than a few weeks in any one place and was never able to converse easily with any of his native informants in their native language, which is uncharacteristic of anthropological research methods of participatory interaction with subjects to gain a full understanding of a culture. In the 1980s, he suggested why he became vegetarian in pieces published in Italian daily newspaper La Repubblica and other publications anthologized in the posthumous book Nous sommes tous des cannibales (2013): "A day will come when the thought that to feed themselves, men of the past raised and massacred living beings and complacently exposed their shredded flesh in displays shall no doubt inspire the same repulsion as that of the travellers of the 16th and 17th century facing cannibal meals of savage American primitives in America, Oceania or Africa." Claude Levi-Strauss was an atheist.
QUESTION: when did he start his career in anthropology
IN: Harriet Tubman (born Araminta Ross, c. 1822 - March 10, 1913) was an American abolitionist. Born into slavery, Tubman escaped and subsequently made some thirteen missions to rescue approximately seventy enslaved people, family and friends, using the network of antislavery activists and safe houses known as the Underground Railroad. She later helped abolitionist John Brown recruit men for his raid on Harpers Ferry.

By 1840, Tubman's father, Ben, was manumitted from slavery at the age of 45, as stipulated in a former owner's will, though his actual age was closer to 55. He continued working as a timber estimator and foreman for the Thompson family, who had held him as a slave. Several years later, Tubman contacted a white attorney and paid him five dollars to investigate her mother's legal status. The lawyer discovered that a former owner had issued instructions that Rit, like her husband, would be manumitted at the age of 45. The record showed that a similar provision would apply to Rit's children, and that any children born after she reached 45 years of age were legally free, but the Pattison and Brodess families had ignored this stipulation when they inherited the slaves. Challenging it legally was an impossible task for Tubman. Around 1844, she married a free black man named John Tubman. Although little is known about him or their time together, the union was complicated because of her slave status. Since the mother's status dictated that of children, any children born to Harriet and John would be enslaved. Such blended marriages - free people of color marrying enslaved people - were not uncommon on the Eastern Shore of Maryland, where by this time, half the black population was free. Most African-American families had both free and enslaved members. Larson suggests that they might have planned to buy Tubman's freedom. Tubman changed her name from Araminta to Harriet soon after her marriage, though the exact timing is unclear. Larson suggests this happened right after the wedding, and Clinton suggests that it coincided with Tubman's plans to escape from slavery. She adopted her mother's name, possibly as part of a religious conversion, or to honor another relative.
