Born 13 Oct 1787; died 1854 .
English writer, painter and inventor. In 1819 a patent was granted to William Brockendon for a diamond wire drawing die. In 1843, he was granted U.K. patent number 9977 for forming tablets: "For the shaping of pills, lozenges and black lead by pressure in a die." Previous practice was to form pills from wetted powders, rolled out rather like pastry, cut to size and then 'balled' by rolling. Also in 1843 he patented an artificial plumbago lead for pencils. He also experimented to make an effective rubber bottle stopper. Brockendon is reputed to have coined the name "vulvanization" for Goodyear's rubber curing process.
