Tove Marika Jansson (Swedish pronunciation: [ˈtuːve ˈjɑnson] (listen); 9 August 1914 – 27 June 2001) was a Swedish-speaking Finnish author, novelist, painter, illustrator and comic strip author. Brought up by artistic parents, Jansson studied art from 1930 to 1938 in Stockholm, Helsinki and Paris. Her first solo art exhibition was in 1943. At the same time, she was writing short stories and articles for publication, as well as creating the graphics for book covers and other purposes. She continued to work as an artist and a writer for the rest of her life.
Jansson wrote the Moomin books for children, starting in 1945 with The Moomins and the Great Flood. The next two books, Comet in Moominland and Finn Family Moomintroll, published in 1946 and 1948 respectively, were highly successful in sales, adding to sales of the first book. For her work as a children's writer she received the Hans Christian Andersen Medal in 1966. The Moomins also spun off to a comic strip, initially created by Jansson herself, and in 2016 Jansson was included in The Will Eisner Award Hall of Fame.
Starting with the semi-autobiographical Bildhuggarens dotter (Sculptor's Daughter) in 1968, Jansson wrote six novels, including the admired Sommarboken (The Summer Book), and five books of short stories for adults.
