Sven Elvestad
Norwegian writer (1884–1934)
Sven Elvestad (7 September 1884 – 18 December 1934) was a Norwegian journalist and author. He is best known for his detective stories, which were published under the pen name Stein Riverton and translated into several languages, including German and English.
Elvestad was born Kristoffer Elvestad Svendsen, in Fredrikshald (now Halden), a small town near the Swedish border. After, as a young office boy, embezzling money from his employer, he changed his name and started a new life as a journalist in Kristiania (Oslo).
As a reporter, he often staged his own sensations. Among his most famous stunts, was spending a day in a circus lion's cage. But he was also the first foreign reporter to interview Adolf Hitler (whom he, despite his fascist sympathies, described as "a dangerous man").
He started writing crime stories, first as semi-documentary reports from the view of the reporter or as told by the retired police detective Asbjørn Krag (modelled on one or two well-known policemen). Soon Krag was developed into a classical private detective (though still with excellent connections to the police force).
In 1908 Elvestad (under the pen name Kristian F. Biller) created the police detective Knut Gribb: a character that was taken over by several other writers in various magazines and series of paperbacks, and still exists.

Why this record matters
The phrase “norwegian writer (1884–1934)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Aug 26, 2026. The linked authority identifier is Q3498167. VIAF identifies the subject as 47005668. The Library of Congress control number is n85284209. 4 of 4 selected statements include explicit references; 0 carry qualifiers and 1 use preferred rank. The first chronological checks are 1884, 1934 and 1908.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
