Peach was a silk merchant in London, and a partner in the banking firm of Peach, Fowler and Co.; he was responsible, among others, for prosecuting Dr. Dodd, and incurred some unpopularity because of it.
In 1780, Peach contested Hindon jointly with John Saunders, another London merchant, against the combined Beckford and Calthorpe interests, but was ignominiously defeated. In 1781 he went bankrupt.
Peach died 14 Dec. 1790.
