George Chalmers (1742 – 31 May 1825) was a Scottish antiquarian and political writer. Chalmers was born at Fochabers, Moray; his father, James Chalmers, was a grandson of George Chalmers of Pittensear in Lhanbryde. After completing a course at King's College, Aberdeen, he studied law at the University of Edinburgh for several years.Two uncles on the father's side had settled in British North America, and Chalmers visited Maryland in 1763, apparently to assist in recovering a tract of land about which a dispute had arisen. He began practising as a lawyer at Baltimore. As a Loyalist, however, at the outbreak of the American War of Independence, he abandoned his professional prospects and returned to Great Britain. Several years then passed before he found adequate employment.In August 1786, Chalmers was appointed chief clerk to the committee of Privy Council on matters relating to trade, following its re-establishment. He retained this position for the rest of his life. It left him time to write.Chalmers was a fellow of the Royal Society and the Society of Antiquaries of London, an honorary member of the Antiquarian Society of Scotland, and a member of other learned societies. His library was left to his nephew, at whose death in 1841 it was sold and dispersed.
