Joseph Bazalgette
Sir Joseph William Bazalgette (; 28 March 1819 – 15 March 1891) was a British 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.
