In 1780 William Leaf opened the first wholesale silk warehouse in London, at 110 Fleet Street.
The firm underwent a number of name changes over the next century before becoming Leaf, Sons & Co., then Leaf & Co. Ltd in 1877.
In 1832 John F. Pawson established I. F. Pawson & Co., a textile and clothing wholesaling company based at 5 and 9 St. Paul’s Churchyard, London. The business was later styled as Pawson & Co., becoming Pawson & Co. Ltd in 1873.
In 1892 the two textiles companies merged to become Pawsons & Leafs Ltd.
The company operated from Pawson’s original premises at St. Paul’s Churchyard until 1964, when the business relocated to 32/43 Chart Street. The company appears to have ceased trading some time after 1968.
