Thomas Twyford


Thomas William Twyford (1849 – 1921) was a pottery manufacturer in England. He invented the single piece, ceramic flush toilet. At the time of Twyford's death he was recognized as a leading pioneer in the application of principles of hygiene to sanitary appliances.

Thomas William Twyford was born the eldest son to Thomas Twyford and Sarah Jones of Hanover Street, Hanley, Stoke-on-Trent, Staffordshire. Twyford's father established two different located earthenware factories: the Bath Street works in Hanley, and the Abbey works in Bucknall. He was able to build a substantial trade-base in both the mainland of Europe and the United States.

In September 1872, Twyford's father died, leaving him the family business. However, the company was under management and control by trustees for a short period before he was able to take over.

In March 1879, Twyford released his first sanitaryware catalogue. The 1870s proved to be a defining period for the sanitary industry and the water closet; the debate between the simple water closet trap basin made entirely of earthenware and the very elaborate, complicated and expensive mechanical water closet would fall under public scrutiny and expert opinion. In 1875, the "wash-out" trap water closet was first sold and was found as the public's preference for basin type water closets. By 1879, Twyford had devised his own type of the "wash out" trap water closet; he titled it the "National". The National met all of the requirements of the quintessential wash-out trap water closets, most defining, the shallow basin water reserve that would be forced through the water-sealed trap when flushed. The National came out as the market place's most popular wash-out water closet.

In 1881, Twyford's National had won an honorary award at sanitary exhibitions at Kensington and Brighton. In 1882, with the success granted by the National, Twyford released a second wash-out closet entitled "The Crown", and in 1883, he designed and released his third wash-out closet named "The Alliance". All three models were not free-standing and required the support of a wooden seat within a substratum wooden enclosure to hold the contraptions.
