History: Bathing Machine Devices On The Beach, 18th-19th Century, Europe

History
According to some sources, the bathing machine was developed in 1750 in Margate, Kent, though this may relate primarily to the "modesty hood" (bathing costumes were not yet common and most people bathed naked). "Mr. Benjamin Beale, a Quaker, was the inventor of the Bath Machine. Their structure is simple, but quite convenient; and by means of the umbrella, the pleasures of bathing may be enjoyed in so private a manner, as to be consistent with the strictest delicacy." In Scarborough Public Library there is an engraving by John Setterington dated 1736 which shows people bathing and popularly believed to be first evidence for bathing machines, however Devon claims this was a year earlier in 1735.
Bathing machines were most common in the United Kingdom and parts of the British Empire with a British population, but were also used in France, Germany, the United States, Mexico, and other nations. Legal segregation of bathing areas in Britain ended in 1901, and the bathing machine declined rapidly. By the start of the 1920s bathing machines were almost extinct, even on beaches catering to an older clientele.
The bathing machines remained in active use on English beaches until the 1890s, when they began to be parked on the beach. They were then used as stationary changing rooms for a number of years. Most of them had disappeared in the United Kingdom by 1914. However, they have survived to this day as bathing boxes in many parts around the world.
