macintosh 1. The process of creating waterproof cloth
by bonding fabric and rubber, invented and patented by
Scottish chemist Charles Macintosh in 1823 as Patent
Waterproof Indiarubber Cloth, after he noticed that coal
tar naphtha dissolved rubber. Macintosh was not the
first to experiment with rubber coating of fabric, but he
became its most successful promoter. By the 1830s,
macintosh fabric was widely used for rainwear, despite
the fact that the 19th-century versions of rubberized
fabric quickly became quite smelly. (Various treatments
and tricks were offered to counterattack this unfortunate
quality throughout the rest of the century.) The
correct spelling of the man's name, the fabric, and the
resulting raincoat is Macintosh, without a "k"; although
"mackintosh" had become an accepted variant when
referring to the raincoat. 2. Generic reference to a
raincoat (made of any material), especially in British
usage; derived from the long association of the rubberized
fabric with protective raingear. Often abbreviated
to mac. Variant spelling: mackintosh. 3. A popular
pattern of tartan.
