F. W. L. Thomas
Captain Frederick William Leopold Thomas FSA (Scot) was a Royal Navy officer, photographer, and historian, noted for his surveys of Scotland, and for taking the first photographs of St Kilda.
Life
Thomas was born about 1812, his father George Thomas being a Master in the Royal Navy. He joined his father's surveying ship, in January 1827. He passed his examination in 1835. He served as mate and assistant surveyor in Investigator, and then in HMS Mastiff, also under his father's command. He was promoted to Lieutenant in 1841, taking command of the Woodlark. He was promoted to Commander in 1860, and retired with the rank of Captain in 1864. He married Frances Sarah Bousfield on 2 December 1841. They had one child, a son, who died in 1850. Thomas died in Edinburgh in 1885.Surveying on sea and land
His work as a hydrographic surveyor was mainly in Scotland. The earliest work, when he was assisting his father, was in Orkney, and he continued this after his father's death. He was then employed in the Firth of Forth and later in the Western Isles. His surveying work resulted in at least 15 charts and several contributions to Sailing Directions. As well as hydrographic surveying, Thomas carried out important work on the archaeology of the northern and western isles. This involved relatively little excavation, but much surveying and recording. He authored several papers on this work, from 1851, including a plan of the barrows, standing stones and other structures around Stenness, Orkney which was the first detailed survey of this area; and descriptions of buildings such as black houses, beehive houses and brochs in the Outer Hebrides.Plan of the antiquities of Stenness, Orkney, from Thomas
Naturalist
Thomas was also important as a naturalist, mainly collecting zoophytes and molluscs. His specimens are frequently referred to in the major works on zoophytes by Johnstonand on molluscs by Forbes and Hanley and Jeffreys. Rendall regarded Thomas as particularly important among the early conchologists, particularly for his work in Orkney. He provided details of the location and depth in which specimens were found, and many of his specimens were of rarer species, indicating that he was familiar with the commoner ones.
