Hans Olav Lahlum
Norwegian chess player

Hans Olav Lahlum (born 12 September 1973) is a Norwegian historian, crime author, chess player and organizer, and politician. He has written biographies on Oscar Torp and Haakon Lie, and a history book about all the Presidents of the United States.
On May 22–23, 2013, he was interviewed by VG for 30 hours, 1 minute and 44 seconds, setting a Guinness World Record for the longest interview ever, beating the previous record by over four hours.
Career
Born in Mo i Rana, Lahlum grew up in Rødøy Municipality, a small community that he did not find enjoyable; he called his own childhood "gloomy". Lahlum finished his cand.philol. degree (master's degree) in history from the University of Oslo in 2002, including subjects in political science and history of religion. Since completing his studies, he has at times been a lecturer and advisor at the Lillehammer University College.
Biographies and history books
His first biography was a 560-page book on former prime minister Oscar Torp, which was published in 2007. The history book on the US presidents was published in 2008. The biography included regular biographical coverage of each president's policy, but also more "tabloid" coverage about matters such as relationship trouble and drinking habits.

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 Q3126992. VIAF identifies the subject as 58869054. The Library of Congress control number is no2007116944. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1973, 2013, 2002 and 2007.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
