at the Royal College of Science, working and teaching there for the next six years. This was a government position, with the appointment being made by the "Lords of the Committee of Council on Education". One of the honours accorded him during this period was his election in 1871 to the Royal Irish Academy. On 5 June 1873 he married the artist Phoebe Anna Moss (Phoebe Anna Traquair), whom he had met in Dublin. They moved to Colinton Farm south-west of Edinburgh. They had three children: Ramsay (1874); Henry (Harry) Moss (1875); and Hilda (1879). That same year, Traquair was transferred (again by the government) to Edinburgh to become the first Keeper of the Natural History Collections at the Museum of Science and Art (later the Royal Scottish Museum). This position had been created by the government to ensure that the museum collections remained independent rather than under the control of the University of Edinburgh's Professor of Natural History, Wyville Thomson. Traquair would spend the next 33 years working in Edinburgh in charge of the museum's natural history collections, building up a large collection of fossil fish. One of the locations where Traquair carried out work on fossil fish was the gorge of Dura Den, in Fife, Scotland, and his collection from here and elsewhere was considered one of the finest in the world at the time. The deposits that he studied included the Old Red Sandstone and the Carboniferous rocks of Scotland. Fossil fish that he classified included the Palaeoniscidae and the Platysomidae, overturning earlier work by Louis Agassiz. Much of this work was published over a period of some 37 years as a series of monographs from the Palaeontographical Society, with some parts being published posthumously. In 1881, Traquair was elected a Fellow of the Royal Society of London. He was also a visiting lecturer at the Natural History Museum in London (then part of the British Museum), twice being appointed 'Swiney Lecturer on Geology at the British Museum (Natural History)' for two five-year periods, from 1883 to 1887 and then again from 1896 to 1900. Traquair was also a Fellow of the Royal Society of Edinburgh and a Fellow of the Geological Society of London. He was elected a Fellow of the Royal Society of Edinburgh in 1874, also serving several periods as Councillor, and being a Vice-President of the Society from 1904 to 1910. He was
