During the Second World War, Williams insisted - despite some controversy - on the right to education, in particular in current affairs, for servicemen and women, and so in mid-1941 Williams established the
Army Bureau of Current Affairs (ABCA) and ran it for the duration of the war. For this role, he became known as
ABCA Bill. The ABCA was a programme of general education for citizenship for servicemen and women: officers attended courses on conducting discussions groups, and these were started as hourly sessions each week. Such was the response that ABCA rapidly expanded resulting in photographic display; wall newspapers articles written by the men themselves; and an "Anglo American Brains Trust". The ABCA is often credited with having an impact on the result of the 1945 General Election and played an important part in post-war period during the building of the "new peace". After the war and under the auspices of the
Carnegie Trust, Williams transformed the ABCA into the Bureau of Current Affairs, moving their offices to Piccadilly in London and continued their activities in peace-time with the assistance of several ABCA contributors including the artists
James Boswell. By 1945, 46 art organisations were funded by CEMA and in 1946 CEMA was re-chartered as the
Arts Council, with Williams as the Council's first Secretary General. ==Later career==
