Starting with a small grocery business begun by his father, William Lever (later created, in June 1917, The 1st Baron Leverhulme and, in December 1922, further elevated to being The 1st Viscount Leverhulme) and his brother James entered the soap business in 1885 by buying a small soap works in Warrington. The brothers teamed up with a Cumbrian chemist, William Hough Watson, who became an early business partner. Watson invented the process which resulted in a new soap, using glycerin and vegetable oils such as palm oil, rather than tallow. The resulting soap was a good, free-lathering soap, at first named Honey Soap then later named "Sunlight Soap". Production reached 450 tons per week by 1888. Larger premises were built on marshes at Bromborough Pool on the Wirral Peninsula at what became Port Sunlight, then part of Cheshire. Though the company was named Lever Brothers, William Lever's brother and co-director James never took a major part in running the business. He fell ill in 1895, probably as a result of diabetes, and resigned his directorship two years later.
