Charles MacIntosh, Inventor of the MacIntosh, FRS

https://en.wikipedia.org/wiki/Charles_Macintosh

Charles Macintosh FRS (29 December 1766 – 25 July 1843) was a Scottish chemist and inventor of waterproof fabrics. The Mackintosh raincoat (the variant spelling is now standard) is named for him.

Macintosh was born in Glasgow, and was first employed as a clerk. He devoted all his spare time to science, particularly chemistry, and before he was twenty resigned his clerkship to take up the manufacture of chemicals. In this he was highly successful, inventing various new processes. His experiments with one of the by-products of tar, naphtha, led to his invention of waterproof fabrics, the essence of his patent being the cementing of two thicknesses of cloth together with natural (India) rubber, the rubber being made soluble by the action of the naphtha. For his various chemical discoveries he was, in 1823, elected a fellow of the Royal Society.

In 1828, he became a partner with James Beaumont Neilson in a firm to exploit the latter's patent for the hot blast blowing of blast furnaces, which saved considerably on their fuel consumption.

Macintosh married, in 1790, Mary Fisher, daughter of Alexander Fisher a merchant of Glasgow. Charles Macintosh died in 1843 at Dunchattan, Scotland, and was buried in the churchyard of Glasgow Cathedral.

Inventor of waterproof fabric; The Mackintosh raincoat'

From Wikipedia - Macintosh was born in Glasgow, Scotland, the son of George Macintosh and Mary Moore, and was first employed as a clerk. 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. In this he was highly successful and invented various new processes. His experiments with naphtha led to his invention of waterproof rubberized fabric; the essence of his patent was the cementing of two thicknesses of cloth together with natural rubber. The rubber is made soluble by the action of the naphtha.[3] The naphtha was prepared by distillation of coal tar, with the Bonnington Chemical Works being a major supplier.[4]

Macintosh married Mary Fisher in 1790, daughter of Alexander Fisher, a Glasgow merchant. They had one son, George Macintosh (1791–1848). In 1823, he was elected a fellow of the Royal Society for his chemical discoveries. In 1828, he became a partner with James Beaumont Neilson in a firm to exploit the latter's patent for the hot blast blowing of blast furnaces, which saved considerably on their fuel consumption.[5]

Charles died in 1843 and was buried in the Glasgow Cathedral graveyard.[6] He is buried with his parents in the ground of his great grandfather, John Anderson of Douhill, Lord Provost of Glasgow. His name is added to the 17th century monument which stands against the eastern boundary wall. 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.
