Dikken Zwilgmeyer (Barbara Hendrikke Wind Daae Zwilgmeyer, 20 September 1853 – 28 February 1913) was a Norwegian children's writer, and is regarded among the most significant innovators of Norwegian children's literature around 1900.
She was born in Trondheim as the daughter of later stipendiary magastrate and Member of Parliament Peter Gustav Zwilgmeyer and Margrethe Gjørvel Daae. She and her family lived in Risør from the time she was 8 years old. Her uncle Ludvig Daae was a politician and Minister of the Army. She did not marry, and died in Kongsberg in 1913.
Zwilgmeyer had no formal education. She showed early talent for painting and writing, and took lessons with various painters, including Christian Krohg. Her first published story was "En Hverdagshistorie", printed in the magazine Nyt Tidsskrift in 1884. Her first story for children was "Afbrudt 17. mai", published in the magazine Illustreret Tidende for Børn. Her first children's book was Vi børn, from 1890, signed "Inger Johanne, 13 years old". This book became a great success, and eleven more "Inger Johanne" books followed. Among these are Karsten og jeg from 1891, Fra vor by from 1892, and Barndom from 1895. Anniken Præstgaren from 1900 is probably the book with largest audience. It is estimated that Zwilgmeyer's books were printed in 600,000 copies up to 1903. "Inger Johanne" remained a favourite for Norwegian children for generations, and Zwilgmeyer's books are regarded as a significant innovation of Norwegian children's literature around 1900.
In 1895 she published her first book for adults, the short story collection Som kvinder er, about the poor circumstances for unmarried women, and in 1896 the puberty novel Ungt sind. These books were more or less met with silence from the contemporary literary critic. The collection Som kvinder er was reissued in 1953, and then received as a forgotten literary pearl from the 1890s. In the 1900s she wrote histrorical novels and stories, including the collection Mægler Porsvold og andre historier from 1902, and the novels Emerentze (1906), Maren Ragna (1907) and Thekla (1908).
What Happened to Inger Johanne was translated into English by Emilie Poulsson, a Scandinavian American children's author. Accompanied with illustrations by Florence Liley Young, the English language version was published in Boston in 1919.
