The East Greenwich Gas holder was the largest built in Europe, to revolutionary technical standards. Modern Movement design, an icon for the area and a landmark. It is going to be demolished because that is what the builders of the Silvertown tunnel want. The talk will cover the backgrounds of the South Metropolitan Gas Company and its charismatic chairman, and how the building of East Greenwich Gas Works in the 1880s was an expression of his ideas of both industrial management and how society should be organized. I will also talk about the structure of the holder and the other holder which once stood beside it, explosions and accidents and about the current campaign which has tried to save the holder against all the odds.
