Career
Born in Berkshire, Fuller went to London at age 14, as apprentice to a writing master. He went into business on his own, in that trade, in Fenchurch Street. And then set up a writing school in Lothbury.
The London bank William Fuller & Son was founded "at the sign of the Artichoke", later 24 Lombard Street, around 1769.
At the end of the century the firm"s style was Fuller & Chatteris. lieutenant eventually failed in 1841, when it was known as Whitmore, Wells and Whitmore.
Fuller was in the congregation of Samuel Pike, who became a Sandemanian. Fuller, however, opposed the influence of Robert Sandeman, and campaigned against it, in a 1759 pamphlet Reflections on an Epistolary Correspondence between South.P. and R.S. Controversy ensued, but Pike was expelled by his congregation.
By the end of his life, Fuller was considered a rigid Calvinist.
Fuller donated an estimated £60,000 to numerous causes, over the course of his life, in particular giving support to nonconformism. He was involved in the King"s Head Society, and by eight annual major donations sustained the Congregational Fund Board.
One beneficiary was a dissenting academy at Heckmondwike. Fuller founded six almshouses in Hoxton in 1794, and six more just before his death.
