Erich Kastner was born in Dresden in Germany in 1899. Much like Emil himself Erich Kastner was an only child. He was devoted to his mother who worked as a hairdresser to supplement their family income. Erich Kastner went into the army in 1917, and his experiences there made him feel strongly that war and violence were wrong. He published Emil and the Detectives in 1928 and Emil and the Three Twins in 1933. The books were very popular but when Hitler's government - the Nazis- were in power Kastner's books were labelled anti-German. Joseph Goebbels, who was in charge of the Government Propaganda, said In the name of the fight against decadence and moral corruption! In the name of breeding and rectitude in state and family, I consign to the flames the writings of Heinrich Mann, Ernst Glasser and Erich Kastner! Erich Kastner was one of the only authors who was present as his books were tossed on to the flames in 1933. Luckily, Hitler and Goebbels may have thrown Kastner's books on to the flames in 1933, but Emil has outlasted them and lives to spy another day. Erich Kastner was awarded the American Library Association Mildred L. Batchelder Award and the Hans Christian Andersen Award. He died in 1974. Walter Trier was the celebrated illustrator of many children's books. He illustrated several other of Erich Kastner's children's books, including The Flying Classroom and Emil and the Three Twins.
Emil and the Three Twins is that very rare thing - a successful sequel Observer Emil's Berlin, and the Baltic resort of its sequel Emil and the Three Twins, were as vivid to me as Arthur Ransome's English Lakeland -- Philip Pullman Independent
