Alexander Cumming was born in Edinburgh 1733 and initially worked as a clock and watchmaker in Inveraray. In 1757 Cumming, along with his brother James, was employed by Archibald Campbell, the third Duke of Argyll, to install the organ and supply a longcase clock for his new castle at Inveraray. Cumming subsequently moved to London (perhaps shortly after the death of his patron in 1761) and by 1763 had been appointed as a member of the commission to adjudicate Harrisons marine timekeeper. In 1765 Cumming presented his celebrated barograph clock for King George III before completing his best-known work on horology Elements of Clock and Watch Work Adapted to Practice in 1766. In 1781 he was made an Honoury Freeman of the Clockmakers Company and in the early 1790s retired to Pentonville from where he continued to write various papers including Observations on the effects which carriage wheels, with rims of different shapes, have on the roads published in 1797. Alexander Cumming died in 1814 leaving his business to his nephew, John Grant.
