She took her son with her as they travelled to stay with various relatives during the war. They would remain in one place until Margharita decided to move, either because of concern for their safety, or because of friction among family members. Later in life Chatwin recalled of the war, "Home, if we had one, was a solid black suitcase called the Rev-Robe, in which there was a corner for my clothes and my Mickey Mouse gas mask." During the war Chatwin and his mother stayed at the home of his paternal grandparents, who had a curiosity cabinet that fascinated him. Among the items it contained was a "piece of brontosaurus" (actually a mylodon, a giant sloth), which had been sent to Chatwin's grandmother by her cousin Charles Milward. Travelling in Patagonia, Milward had discovered the remains of a giant sloth, which he later sold to the British Museum. He sent his cousin a piece of the animal's skin, and members of the family mistakenly referred to it as a "piece of brontosaurus". The skin was later lost, but it inspired Chatwin decades later to visit and write about Patagonia. After the war, Chatwin lived with his parents and younger brother Hugh (19442012) in West Heath in Birmingham, where his father had a law practice. At the age of seven he was sent to boarding school at Old Hall School in Shropshire, and then Marlborough College, in Wiltshire. An unexceptional student, Chatwin garnered attention from his performances in school plays. While at Marlborough, Chatwin attained A-levels in Latin, Greek, and Ancient History. Chatwin had hoped to read Classics at Merton College, Oxford, but the end of National Service in the United Kingdom meant there was more competition for university places. He was forced to consider other options. His parents discouraged the ideas he offered — an acting career or work in the Colonial Service in Kenya. Instead, Chatwin's father asked one of his clients for a letter of introduction to the auction house Sotheby's. An interview was arranged, and Chatwin secured a job there. In 1958, Chatwin moved to London to begin work as a porter in the Works of Art department at Sotheby's. Chatwin was ill-suited for this job, which included dusting objects that had been kept in storage. Sotheby's moved him to a junior cataloguer position, working in both the Antiquities and Impressionist Art departments.
