Thomas Thomson FRSE FSA Scot (10 November 1768 – 2 October 1852) was a Scottish advocate, antiquarian and archivist who served as Principal Clerk of Session (1828–1852) and as secretary of the literary section of the Royal Society of Edinburgh (1812–20).After attending the parish school of Dailly, he entered the University of Glasgow at age 13, where he graduated with an MA on 27 April 1789.Of works published by Thomson for the Record Commission, the major one was The Acts of the Parliament of Scotland, 1424–1707, vols 2–11 (1814–1824).1, containing the Regiam Majestatem, with the oldest recorded Proceedings and Acts of Parliament, was published last; and, although almost complete before 1841, when Thomson's connection with the register office ceased, did not appear until 1844, when it was edited, with additions, by Cosmo Innes.A close associate of Francis Jeffrey and other projectors of the Edinburgh Review, Thomson contributed three papers (on Erasmus Darwin's Temple of Nature (1803); Anna Seward's Memories of the Past (1804); and John Mason Good's Life of Alexander Geddes (1804)); and occasionally undertook the editorship for Jeffrey.
