Historique
"Lawrence and Carlill", sugar refiners, are listed in various trade directories of 1817-1819 as being based at Lehman Street and Rupert Street, Goodman's Fields. By the 1820s the entries list Richard Henshaw Lawrence and Morton William Lawrence, sugar refiners, at the same addresses. They appear to have been in business until the 1840s.
It is unclear what improvement to the refining process Lawrence invented. He is mentioned in the book "Abridgements of Patents for Inventions relating to Sugar, 1663-1866" (Commissioners of Patents, 1871) with the note "No Specification enrolled".
