The Swedish artist Carl Larsson was born in Gamla stan, the old town in Stockholm. His parents were extremely poor and his childhood was not happy. However, at the age of thirteen his teacher at the school for poor children urged him to apply to the "principskola" of the Royal Swedish Academy of Arts and he was admitted. During his first years there, Larsson felt socially inferior, confused, and shy. In 1869, at the age of sixteen, he was promoted to the "antique school" of the same academy. There Larsson gained confidence and even became a central figure in student life.

After several years working as an illustrator of books, magazines, and newspapers, Larsson moved to Paris where he spent several rather frustrating years as a hardworking artist without any success.

In 1882, whilst in Grez-sur-Loing, at a Scandinavian artists' colony outside Paris, he met the artist Karin Bergöö (1859-1928), who soon became his wife. This was to be a turning point in Larsson's life. In Grez, Larsson painted some of his most important works; now in watercolour and very different from the oil painting technique he had previously employed.

Carl and Karin Larsson raised eight children and his family became Larsson's favourite models. Many of his watercolours are now popular all over the world. Their eight children included Suzanne (1884), Ulf (1887, who died at 18), Pontus (1888), Lisbeth (1891), Brita (1893), Mats (1894, who died at 2 months), Kersti (1896) and Esbjörn (1900).

In 1888 the young family was given a small house, named Little Hyttnäs, in Sundborn by Karin's father Adolf Bergöö. Carl and Karin decorated and furnished this house according to their particular artistic taste and also for the needs of the growing family.

Through Larsson's paintings and books this house has become one of the most famous artist's homes in the world. The descendants of Carl and Karin Larsson now own this house and keep it open for tourists each summer from May until October.

Larsson's popularity increased considerably with the development of colour reproduction technology in the 1890s, when the Swedish publisher Bonnier published books written and illustrated by Larsson and containing full colour reproductions of his watercolours, e.g. A Home. However, the print runs of these rather expensive albums did not come close to that produced in 1909 by the German publisher Karl Robert Langewiesche (1874-1931): His choice of watercolours, drawings and text by Carl Larsson, titled Das Haus in der Sonne (The House in the Sun), immediately became one of the German publishing industry's best-sellers of the year - 40,000 copies sold in three months, and more than 40 print runs have been produced up to 2001. Carl and Karin Larsson declared themselves overwhelmed by such success.

Larsson also drew several sequential picture stories, thus being one of the earliest Swedish comic creators.

Carl Larsson considered his monumental works, such as his frescos in schools, museums and other public buildings, to be his most important works. His last monumental work, Midvinterblot (Midwinter Sacrifice), a 6x14 meter oil painting completed in 1915, had been commissioned for a wall in the National Museum in Stockholm (which already had several of his frescos adorning its walls), but was upon completion rejected by the board of the museum. In his memoirs Jag (I) - published after Larsson's death - he declared his bitterness and disappointment over this rejection of the painting he himself considered to be his greatest achievement: "The fate of Midvinterblot broke me! This I admit with a dark anger. And still, it was probably the best thing that could have happened, because my intuition tells me - once again! - that this painting, with all its weaknesses, will one day, when I'm gone, be honoured with a far better placement." He admitted, however, in the same memoirs that the pictures of his family and home "became the most immediate and lasting part of my life's work. For these pictures are of course a very genuine expression of my personality, of my deepest feelings, of all my limitless love for my wife and children."

Fights between different schools of Swedish artists caused the "Midvinterblot" controversy to continue for many years. In 1987 the museum was even offered the monumental painting for free, provided it would adorn the empty wall for which it had been intended, but the museum declined the offer, so the painting was sold to the Japanese collector Hiroshi Ishizuka. In 1992, he agreed to lend it to the museum for its major Carl Larsson exhibition, where it was hung in the intended place. Public appreciation changed the "experts'" view about the painting, and with the help of private donations the museum was able to buy it from Hiroshi Ishizuka in 1997 and permanently display it where it originally had been intended to be.
