Scottish chemist Charles Macintosh died - On this day in history
Charles Macintosh, the Glaswegian scientist who invented the Mackintosh raincoat, died on 25 July 1843. Macintosh began his working life as a clerk and devoted all his spare time to the study of science.
He invented the rainproof fabric which would be made into the Mackintosh coat in 1818, by joining two pieces of India Rubber together. Although best known for this invention, he was also responsible for developing a method of converting iron to steel and for devising a hot-blast process to create cast iron.
