Stenersen was born in Kristiania (now Oslo), Norway as the son of bookseller Johan Martin Stenersen (1866–1948) and Martha Kathrine Eckersberg (1869–1930). He graduated from Kristiania Commerce School (now Oslo Commerce School) in 1918, and studied at Queen's College, Oxford, from 1922 to 1924.[3][4]
He was active on the stock market already as a teenager. From 1925 he was running his own business, A/S Stenersen og Waage, which operated in the rubber business and the Dutch stock market.[4]
He was a friend of painter Edvard Munch from the 1920s, and came to be Munch's financial advisor. He was also a collector of his art work, and had one of the largest private collections of Munch's works.[4] In 1926 he organized an exhibition of his art collection, which centered around works by Munch and Ludvig Karsten. He wrote essays on artists such as Edvard Munch, Erik Harry Johannessen, Jakob Weidemann and Paul Klee. He published books on economy, including Penger og tall from 1937. His début as a fiction writer was the short story collection Godnatt da du from 1931.[4]
He donated his collection of Norwegian art to the municipality of Aker in 1936. From 1994 the collection has been on display in the Stenersen Museum in Oslo.[4] His books were forbidden by the Nazi regime in 1941, and Stenersen had to flee to Sweden. His biography of Edvard Munch from 1944, translated into several languages, was Stenersen's greatest writing success.[4] His play Eva og Johannes from 1953 was staged at Nationaltheatret by Agnes Mowinckel.[5][7][8]
