Ronald Searle, Britain's preeminent cartoonist and caricaturist, died December 30, 2011, in the south of France, at the age of 91. His unique and instantly recognizable style was a huge departure from the editorial, book and advertising illustration of the 1950s, and he quickly became very popular. Besides numerous publications in England, Searle illustrated many covers for the New Yorker, and over 100 books. His work inspired a generation of artists.
