Wessex was originally a brand of pipes by Hall & Fitzgerald Co, then produced in France by Chacom. A wholesaler of pipes, "fancy goods," and tobacconists supplies, Hall & Fitzgerald's hallmark was first registered in England in 1899.

Wessex is likely linked to Wessex Tobacco Company, formed in London in the early 1980s by a group of pipe tobacco experts. Some models have been drawn up by the German architect and designer Peter Kliem, and produced in Saint-Claude factories, with acrylic and cumberland stems.
