Anna Rutgers van der Loeff

Anna Rutgers van der Loeff (1910–1990) was a Dutch writer of children's novels.
Some of her works have been translated into other languages, including English.
Possibly her most popular novel was the 1963 Children on the Oregon Trail (De Kinderkaravaan), an account of a family of children traveling with a pioneer caravan to Oregon in the mid-19th century, loosely based on the real incident of the Sager orphans.
Another popular novel was her 1958 Avalanche, a story of a group of children from an orphanage caught up in heavy snowfall in Switzerland.
She won the Deutscher Jugendliteraturpreis in 1977 and 1957.
