Thomas Crapper

Died 27 Jan 1910 at age 73 (baptized 28 Sep 1836).who owned a flourishing plumbing supply business and held several patents. Though he did not invent the familiar toilet flushing syphon mechanism (it was patented in Britain by Albert Giblin, No. 4990 of 1898), he did widely market it, and thus his name has been associated with it. Before this invention, the lavatory had existed in various forms, dating back to Sir John Harrington in 1589. When Victorian era toilets with poor valve designs were wasting too much water, by act of Parliament, a water-saving device was required. For this reason, the lever-activated syphon “pull and let go” mechanism was marketed as “Crapper's Silent Valveless Water Waste Preventer.”«
