Karl Emanuel Jansson (7 July 1846, in Finström – 1 June 1874, in Jomala) was a Swedish-Finnish painter, primarily of genre scenes.
His initial inspiration to pursue an artistic career came from the parish painter who was teaching him to read and write.
In 1859, the Vicar Frans von Knorring came across some of Jansson's drawings and sent them, along with a letter of recommendation, to the Finnish Art Society [fi].
This resulted in a scholarship for him to study at the Society's drawing school in Turku, overseen by Robert Wilhelm Ekman.
In 1862, he relocated to Stockholm to continue his studies at the Royal Swedish Academy of Arts under Johan Fredrik Höckert.
