7267 Victormeen           Discovered 1943 Feb. 23 by L. Oterma at Turku.
In 1950, Victor Ben Meen (1910-1971) identified as an impact structure what is today known as Pingualuit Meteorite Crater, in northern Quebec. His discovery led to the eventual recognition of many other extraterrestrial impact structures, elsewhere on the Canadian Shield, and beyond.
