Charles Macintosh FRS (29 December 1766 – 25 July 1843) was a Scottish chemist and the inventor of the modern waterproof raincoat.

Charles devoted his spare time to science, particularly chemistry, and before he was 20 resigned his clerkship to study under Joseph Black at the University of Edinburgh,[2] and to take up the manufacture of chemicals.

[3] The naphtha was prepared by distillation of coal tar, with the Bonnington Chemical Works being a major supplier.

[6] He is buried with his parents in the ground of his great-grandfather, John Anderson of Douhill, Lord Provost of Glasgow.

A late 19th century secondary memorial also exists, in polished red granite, slightly to the north, where Charles is again mentioned on the grave of his son, George.
