[1] Sørensen studied drawing at the Norwegian National Academy of Craft and Art Industry in Kristiania in 1904 and from 1906 to 1908.

His painting Varietéartist from 1910 caused big headlines, and was bought by the Swedish painter and art collector Prince Eugén, Duke of Närke.

[1] He is represented in the National Gallery with several paintings, as well as in other Scandinavian museums, and has decorated a large wall at the Oslo City Hall.

He illustrated books by Jørgen Moe, Bjørnstjerne Bjørnson, Ragnhild Jølsen and Aasmund Olavsson Vinje, and painted portraits of the writers Ingeborg Refling Hagen (1932) and Sigurd Christiansen (1936).

Galleries with works by Sørensen were later raised at two of his favourite painting locations, Holmsbu Billedgalleri in 1973, and Vinje Biletgalleri in Smørklepp in 1991.
