Sugar refiners, of Well Street, Whitechapel, London

Proprietor: Lewis [Louis?] Honore Henry German Constant of Wellclose Square.[1]. Note: Constant was French, so there is some doubt about the spelling of several of his Christian names in the source.

1822 Court case: Constant & Co vs. Hague and Thomson (millwrights), concerning damage resulting from the explosion of a cast iron boiler, which killed seven people.[2]
