Executive summary: Invented the raincoat
Self-taught chemist Charles Macintosh went into business for himself at the age of twenty, converting coal-gas waste into ammonia. He later manufactured lead and aluminum acetates, and in 1819 he discovered that naphtha, a liquid hydrocarbon produced as waste matter in the coal gas industry, dissolves rubber. Over the next few years he developed a paint from rubber dissolved by naphtha. By cementing two pieces of cloth together with this naphtha/rubber he invented a waterproof cloth, and used this to manufacture the first raincoats. A waterproof raincoat is still commonly referred to a macintosh (often spelled "mackintosh"), especially in the United Kingdom. Macintosh also invented a bleaching powder, a method for converting iron to steel, and a hot-blast process to manufacture high quality cast iron.
