The first name of the author who won the 1950 Newbery Medal for The Door in the Wall is Marguerite.
The author was Marguerite de Angeli, an American writer and illustrator whose historical novel was published in 1949. Set in medieval England during the Black Death, the story follows Robin, a boy preparing to become a knight who loses the use of his legs. With help from people he meets, Robin develops courage and finds meaningful ways to serve others.
De Angeli illustrated the book herself, adding visual detail to its depiction of medieval life, castles, clothing, music, and daily work. The novel's title refers to the possibility of finding a way forward when an obvious path appears closed—a theme reflected in Robin's physical and emotional journey.
The award date can cause confusion: the book was released in 1949, but it received the Newbery Medal in 1950. De Angeli later received another Newbery distinction for Black Fox of Lorne, which was named a 1957 Newbery Honor book.
