Robert Spear Hudson (d.1884) invented the first dry soap powder, "Hudson's Dry Soap" in 1837 in his small pharmacy in West Bromwich, England, moving to Liverpool in the 1880s. He advertised extensively, first locally and then nationally, as his business and use of his products grew. The firm was taken over by Lever Brothers Ltd. (now part of Unilever) in 1908.
