found: Oxford DNB online, 4 July 2014:under Murray family, publishers (John Samuel Murray, publisher; born 27 November 1778 at 32 Fleet Street, London, the eldest son of John Murray [1737-1793]; when his father died in November 1793 Murray, who was not quite fifteen, was apprenticed to Samuel Highley, his father's assistant, and an agreement was drawn up by which Murray, when he came of age in 1799, would become a full partner of Highley; however, the two partners 'disagreed on too many important matters to work together effectively' and on 24 March 1803, following arbitration, they formally separated, Highley establishing himself as a medical publisher a few doors down at 24 Fleet Street; Murray's move to 50 Albemarle Street in June 1812 placed him at the centre of London literary life; Murray's range of publications was very wide; he died on 27 June 1843)
