William Thomas Greenstreet was born in Attercliffe in 1837, the son of Stephen (a labourer) and Mary.  In 1841, he was living in Woodside, with his widowed mother Mary Ann (d. 1869).  In 1851, Mary was running a lodging house in Nursery Street, with William working as an errand boy.  By 1861, Greenstreet was working as a table knife manager and was listed in the directory (1868).  In the early 1870s, he occupied a warehouse and workshop at 129 Pond Street (next to Old Ponds Goit), where he started to trade as a cutlery factor.  He traded under the name W. T. Greenstreet & Company, Selborne Works.  By 1874, however, he was attempting to let rooms and cutlers’ sides in Pond Street and within two years he apparently vacated his workshop (Sheffield Independent, 4 March 1874, 11 July 1876).  William J. Ward became his ‘successor’.   William Thomas Greenstreet, table knife manufacturer, died on 3 August 1877, aged 40, at Reliance Place, Winter Street.
