I walked on Saturday to the Hackney Museum, on the ground floor of the public library just south of the Hackney Empire. It records the early history of Hackney – Hackney House which was on the site of Homerton Hospital and Balmes House which became an asylum, the market gardens established by Thomas Fairchild and, in 1787, by Conrad Loddiges with hothouses and steam heating. Then the railways came and the city clerks and the streets of smart housing which later turned to slums. There was a home for ayahs off Mare Street and for lascars in Shoreditch. But never the underground.
