Artist and satirical cartoonist, Ronald Searle CBE, was born in Cambridge. He was the son of a postal worker and is best remembered as the creator of the St Trinian's School series of books. He worked as a war artist during the Second World War but was captured and imprisoned.
On his return to the UK, Searle became a well-regarded graphic artist for various advertisers, and publications, producing illustrations in pen and ink. He designed one of the ‘Your Letterbox’ campaign posters which ran between 1958 and 1966, and advised the public to have their letterboxes properly situated for maximum efficiency.
