At school he did so well he was known as the little professor.
At home, in order to escape from the family misery, he began to draw, often surrounded by piles of laundry.
Karl Oscar Isakson (16 January 1878, Stockholm – 19 February 1922) was a Swedish painter who spent much of his professional life in Denmark where he is considered to be one of the fathers of Modernism.
He had close associations with the Bornholm school of painters and made many paintings of Christiansø.
These became his favourite subjects, even though he continued to paint still lifes and models in a Copenhagen studio.
