Erik (Eero) Nikolai Järnefelt (8 November 1863 in Vyborg – 15 November 1937 in Helsinki) was a Finnish painter and art professor. He is best known for his portraits and landscapes of the area around Koli National Park. He studied at St Petersburg Academy of Arts and later at the Académie Julian in Paris. He is known for his panoramic landscape views, but he also treasured the tiniest details of nature as equally valuable subjects. He was even an accomplished portraitist. Nature and reality were the true inspirations for Järnefelt’s art.
