Tove Jansson is born on August 9th, the eldest child of an artistic family.


Tove studies art both in Finland and abroad and she starts making Moomintroll paintings. Her first Moomin-like character is later seen in the magazine Garm in 1943.


Söderström & Co publishes the first Moomin story – The Moomins and the Great Flood – in Swedish. It is the story about Moominmamma’s and Moomintroll’s search for the missing Moominpappa and how they found their way to the Moominvalley.


The second book, Comet In Moominland (Swedish title Kometjakten / Mumintrollet på kometjakt / Kometen kommer) is published. Comet in Moominland is often seen as first novel in the series as it introduces many of the main characters, like Snufkin and the Snorkmaiden, and is set in Moominvalley.


Finn Family Moomintroll (original Swedish title Trollkarlens hatt, ‘The Magician’s Hat’), the third in the series of Tove Jansson’s Moomins books, is published. It owes its title in translation to the fact that it was the first Moomin book to be published in English, and was actually marketed as the first in the series until the 1980s. The 1961 English publication features a foreword “by Moominmamma“, where she explains the nature of Moomins for fear that English children may not have heard of them; she also apologises for her “rottn” English.


The Exploits of Moominpappa is published. It is the fourth book in the Moomin series by Tove Jansson and it will be considerably revised in 1968 under the title Moominpappa’s Memoirs. The story found in this book is mentioned in the previous Moomin books, as Moominpappa writes his memoirs in those stories. Unlike Comet in Moominland and Finn Family Moomintroll, both versions of the novel were translated into English.


The Book about Moomin, Mymble and Little My was the first Moomin picture book by Finnish author Tove Jansson, published in 1952 in Swedish. Moomintroll is taking milk back home to his mother, Moominmamma when he meets The Mymble who is searching for her missing sister Little My. Together the pair go looking for her.


The world’s largest newspaper – London’s The Evening News – starts to publish the Moomin comic strip. The strip reaches up to 20 million readers daily in over 40 countries. It continues until 1974. From 1960, Tove’s brother Lars Jansson draws the strip. The first Moomin products come onto the market.


Moominsummer Madness (Swedish title Farlig midsommar, ‘Dangerous Midsummer’), the fifth in the series of Tove Jansson’s Moomins books, is published. The major theme of the novel is that of theatre, described as an infuriating but ultimately rewarding process.


Moominland Midwinter (Swedish title Trollvinter, Finnish title Taikatalvi), the sixth in the series of Tove Jansson’s Moomins books, is published. This book sees Jansson adopt a darker, more introspective tone compared to the earlier books that is continued in the remainder of the series. Often in the book Moomintrollis either lonely, miserable, angry or scared – the result of being forced to survive in a world to which he feels he does not belong. While preserving the charm of the previous novels, the story involves a more in-depth exploration of Moomintroll’s character than before.


Tove’s first theatre play, Troll i kulisserna (Moomins on Stage), premieres. The first Moomin television series is aired in Germany, a puppet animation produced by Augsburger Puppenkiste.


Who Will Comfort Toffle? is the second picture book in the Moomin series by Tove Jansson. It was first published in 1960. It was first translated into English by Kingsley Hart. The lonely Toffle leaves his home to look for friends, eventually finding the Miffle and rescuing her from The Groke.


Tales from Moomin Valley (Swedish: Det osynliga barnet och andra berättelser) is published. It is the seventh book in the Moomin series and unlike the other books, it is a book of short stories, not a novel.


Moominpappa at Sea (Swedish: Pappan och havet) is published. It is the eighth book in the Moomin book series by Tove Jansson. In the novel the Moomin family is off to live in a lighthouse on a tiny island, because even the home-loving Moomins need a change of scenery sometimes.


Fuji TV Zuiyo Enterprises produces an animated Moomin series in Japan and the Moomins become very popular there.
