Joseph Bazalgette

Sir Joseph William Bazalgette CB (/ˈbæzəldʒɛt/; 28 March 1819 – 15 March 1891) was an English civil engineer. As Chief Engineer of London's Metropolitan Board of Works, his major achievement was the creation of the London Main Drainage, the sewerage system for central London, in response to the Great Stink of 1858, which was instrumental in relieving the city of cholera epidemics, while beginning to clean the River Thames. He later designed the second and current Hammersmith Bridge, which opened in 1887.
