born Sept. 21, 1756, Ayr, Ayrshire, Scot. died Nov. 26, 1836, Moffat, Dumfriesshire Scottish inventor of the macadam road surface. He made an early fortune in his uncle's New York countinghouse (1770-83). Back in Scotland, he noted the poor condition of the highways near his estate and undertook experiments in road making.
