Lever Sales of Port Sunlight, Cheshire. Telephone: Rock Ferry 2000. Cables: Selever, Portsunlight". (1947)
1885 The company was founded by William Hesketh Lever and James Darcy Lever. They bought a small soap works in Warrington. William Henry Watson developed a new formula for soap using vegetable oil in place of tallow. The resultant soap was superior in every respect to all other soaps then on the market. It was named Sunlight and the formula was patented. Using glycerin and vegetable oils such as palm oil, rather than tallow, to manufacture soap, they produced a good, free-lathering soap, called Sunlight Soap. The soaps were made from a mixture of coconut or palm kernel oil, cotton-seed oil, resin and tallow.
1886 Levers were the first to sell soap in cartons .
1887 By the end of this year, Lever and Co was making 450 tons of Sunlight soap a week. William Lever bought a site for a large factory on the banks of the Mersey opposite Liverpool. This was on marshes at Bromborough Pool on the Wirral Peninsula adjacent to Price's soap and candle factory which had opened in 1855. The new development was called Port Sunlight and included a village for its workers.
Lever Brothers was one of several British companies that took a caring, paternalistic interest in the welfare of its employees. This was a major feature of the company's operations right from the start; the model village of Port Sunlight was developed between 1888 and 1914 adjoining the soap factory to accommodate the company's staff in good quality housing, with high architectural standards and many community facilities, amenities and leisure facilities, in the same way that Price's had built a model village for its workers.
