== History ==
Codename Glasgow: 1942 - this operating system was developed by the British government during the war. Notable computer scientists and mathematicians of the time worked on it, including Alan Turing and Max Newman. "Codename Glasgow" was eventually developed into Union Jack OS at the end of the decade.
In 1949, Thomas Bennett died, 18 months after Hudson Robertson. It was decided that the patent of the operating held by the Bennett family was unfair, and thus it was lifted. Union Jack OS was released later that year. Until Acorn's RISC OS, it was the dominant operating system used in Great Britain.
