Lars Wetterling's love for art evoke at school age when he visited a neighbour who had a home filled with art and beautiful furniture. He particularly remembers one painting that touched his heart without him being able to explain why. This experience opened a door into the world of art. In the early 1960s, he became a member of the Friends of the Art Museum, where his expertise and contacts played a significant role.**

In close collaboration with museum directors Gösta Lilja and Bo Sylvan, Lars was instrumental in several important purchases of works by important Swedish artists. Eventually, Lars became chairman of the group Konstklubben, liaising with various artists to purchase works of art for its members and the museum, thus becoming an ambassador for modern Swedish art.

During the years when his own home was filled with art, the absolute criterion was consistently to buy only works that had touched him on a personal level, that in some way recalled the feeling when he experienced the painting in the neighbour's home as a child. Lars Wetterling's collection ranges from post-war art to the present day, from abstract expressionists such as Evert Lundquist to contemporary works by Karin Mamma Andersson.
