History

Walker Crosweller

Walker, Crosweller and Co. Ltd. was founded in London in 1921 by James MacFarlane Walker.

In 1933 the company also made gas and air flow, pressure and vacuum recorders (instrumentation) for industry. These were made by the Arkon Instruments subsidiary.

In 1936 it launched the Leonard thermostatic mixing valves; this was world's first thermostatic shower. In 1937 it moved to Cheltenham, known as the Whaddon Works.

In the Second World War, all shower valves for British military use were made by them. By 1950 the Leonard brand of shower equipment was becoming the main brand used for institutional buildings - schools and hospitals. This was due to persuading the Ministry of Education to install temperature-regulated showers. The thermostatic mixing valves were not just used for showers but for general heating of water, including their thermostatic steam water heaters.
