Edvard Munch (1863-1944) is surely the most famous Norwegian painter. For details regarding his troubled life, you can consult his Wikipedia entry here.
Munch received formal art training, but fell in with artists and others excited by the emerging prospect of modernism. By the time he was 30, he was experimenting with ideas propounded by modernists in France and Germany. Here are examples:

Munch, like many other modernists in this "In the Beginning" series, clearly seems to have had the potential to have been a good representational artist. Indeed, he was off to a good start in this direction. Such a start is not surprising when one considers his generation: he was a near-contemporary of Gustav Klimt who began his own professional career painting academic-style works.
