John Mercer (archaeologist)
John Barry Mercer (1934 –July 1982) was a British archaeologist, author, weaver, and human rights advocate. Born in Las Palmas, Canary Islands, to British parents, he was educated in Spain and England. Having qualified as a chartered accountant by the age of 21, he worked for Price Waterhouse in Paris for a couple of years and then dropped out, first to Ibiza and then Menorca. Following his passion for islands, he subsequently moved to Lealt, a remote house on the Scottish island of Jura in the Inner Hebrides where, in the 1960s and 70s with his partner  Susan Searight, he researched and painstakingly excavated numerous coastal sites. His many papers have established Jura as a significant Mesolithic area. Whilst at Lealt, as well as his archaeological work, he lived off-grid, built his own loom from driftwood, invented a spinning wheel from recycled parts, and established a workshop to spin, dye and weave the local blackface wool into rugs. He was a committed human rights researcher and activist, particularly in the Western Sahara and Mauritania, contributing influential research reports to the Minority Rights Group and also the Anti-Slavery Society. His report on slavery in Mauritania has  been widely cited. The "John Mercer Human Rights Trust", set up after his death, commemorates this strand of his life. Mercer's first books were for young people, "Lizard Island Expedition" and "The Cormorant and the Stranger", drawing on his own experiences in the Balearics. He wrote an illustrated guidebook to the islands of Colonsay, Gigha and Jura and several books on the Canary Islands. An independent thinker with eclectic interests, he also wrote about, amongst other topics, hand-spinning, communes, and Scottish devolution. He was a Fellow of the Institute of Linguists, of the Royal Scottish Geographical Society, and  of the Society of Antiquaries of Scotland. John Mercer died from motor neurone disease at Lealt at the age of 48.
