Sir John Murray (3 March 1841 – 16 March 1914) was a pioneering Canadian-born British oceanographer, marine biologist and limnologist. He is considered to be the father of modern oceanography. Early life and education Murray was born at Cobourg, Canada West (now Ontario) on 3 March 1841. He was the second son of Robert Murray, an accountant, and his wife Elizabeth Macfarlane. His parents had emigrated from Scotland to Ontario in about 1834. He went to school in London, Ontario and later to Cobourg College. In 1858, at the age of 17 he returned to Scotland to live with his grandfather, John Macfarlane, and continue his education at Stirling High School. In 1864 he enrolled at University of Edinburgh to study medicine however he did not complete his studies and did not graduate. In 1868 he joined the whaling ship, Jan Mayen, as ship's surgeon and visited Spitsbergen and Jan Mayen Island. During the seven-month trip, he collected marine specimens and recorded ocean currents, ice movements and the weather. On his return to Edinburgh he re-entered the University to complete his studies (1868–72) in geology under Sir Archibald Geikie. Challenger Expedition In 1872 Murray assisted in preparing scientific apparatus for the Challenger Expedition under the direction of the expedition's chief scientist, Charles Wyville Thomson. When a position on the expedition became available Murray joined the crew as a naturalist. During the four-year voyage, he assisted in the research of the oceans including collecting marine samples, making and noting observations, and making improvements to marine instrumentation. After the expedition, Murray was appointed Chief Assistant at the Challenger offices in Edinburgh where he managed and organised the collection. After Thomson's death in 1882, Murray became Director of the office and in 1896 published The Report on the Scientific Results of the Voyage of HMS Challenger, a work of more than 50 volumes of reports. Murray renamed his house, on Boswall Road in northern Edinburgh, Challenger Lodge in recognition of the expedition. The building now houses St Columba's Hospice. Marine Laboratory, Granton In 1884, Murray set up the Marine Laboratory at Granton, Edinburgh, the first of its kind in the United Kingdom. In 1894, this laboratory was moved to Millport, Isle of Cumbrae, on the Firth of Clyde, and became the University Marine Biological Station, Millport, the forerunner of today's Scottish Association for Marine Science at Dunstaffnage, near Oban, Argyll and Bute.
