Avery Hill Mansion and the Winter Garden were created by Col John Thomas North ‘Nitrate King’ in 1890. But he didn’t get long to enjoy his house, as he died suddenly in 1896. In his obituary he was described as “a solid, sturdy Yorkshireman, shrewd, honest”.
John Thomas North was born in Leeds in 1842 and was apprenticed to a machine manufacturer. He was sent to South America to superintend machinery there. While there he found vast deposits of nitrate of soda and he realised the commercial value of this as fertiliser. This made him very wealthy. On his return to London he became a familiar face in the City, built himself an extravagant house at Avery Hill and became Honorary Colonel of the Tower Hamlets Volunteer Engineers. He had risen from mechanic to millionaire. But his business empire collapsed, and after he died his widow sold Avery Hill.
