Tove Jansson’s life was unconventional. “I only want to live in peace,” she once said, “plant potatoes and dream!” The artist and children’s book author was born in 1914. Her family was bohemian and lived in Helsinki, the Finnish capital. Jansson wrote her first Moomins book in 1945, The Moomins and the Great Flood, which propelled her to worldwide stardom. Over the course of the series, which ended in 1970 with the ninth book, Moominvalley in November, a family of trolls with large round snouts navigate supernatural landscapes, comets, meteors, and dangerous forests, charming children all over the world. The Brooklyn Public Library now hosts the first U.S. exhibition dedicated to Jansson and the Moomins universe. The show includes immersive installations, archival materials, multilingual editions of the books, and public programming for all ages. —Elena Clavarino
