Sophia Jansson (b. 1961) is the chairman of the board of Moomin Characters and, together with other heirs, is responsible for Tove Jansson’s estate. She is the daughter of Tove Jansson’s brother Lars. Her debut, Three Islands - Mom, Dad and Me, a memoir, was published in autumn 2025. The book is a gripping story of family, the price of silence and the liberating power of storytelling. Sophia’s father, Lars and mother Nita’s relationship was not built on passionate love, but they shared the most important thing in life: a child. Sophia Jansson’s autobiography features three islands: Tonga, where the Jansson siblings wanted to move to in the 1940s, Ibiza, where Sophia lived in her early childhood, and the island in Pellinge, where the Janssons have spent time over generations.
