Aleksandr Kuznetsov was the expedition leader of the first undisputed team to set foot on the North Pole.[1] Other claimants, notably Frederick Cook (1908) and Robert Peary (1909) have been criticized for a lack of supporting logs, having no one to confirm sextant readings or other reasons.
Kuznetsov led the Sever-2 team of Soviet scientists who flew and landed three Lisunov Li-2s at the North Pole on April 23, 1948.[2] Soundings made by the team were the first to indicate an underwater mountain ridge beneath the ice and water at the North Pole.[3]
