Dicker’s family was connected with the Devon wool trade. He himself went to Jamaica as a young man; became an influential merchant, and acquired ‘a very large estate there’.
In 1754 he was returned at Plymouth with Government support. No vote or speech by him is reported.
Dicker maintained his connexion with the West Indies, and in 1757, together with William Beckford and Rose Fuller, was consulted by the Board of Trade about West Indian affairs.
Dicker spent large sums in building bridges over the Thames—according to Grosley’s A Tour to London
