In page Jan Tschichold:
"Between 1947 and 1949 Tschichold lived in England, where he oversaw the redesign of 500 paperbacks published by Penguin Books, leaving them with a standardized set of typographic rules, the Penguin Composition Rules.[6] Although he gave Penguin's books (particularly the Pelican range) a unified look and enforced many of the typographic practices that are taken for granted today, he allowed the nature of each work to dictate its look, with varied covers and title pages. In working for a firm that made inexpensive mass-market paperbacks, he was following a line of work — in cheap popular culture forms (e.g. film posters) — that he had always pursued during his career.[citation needed] He was succeeded at Penguin by Hans Schmoller.
