The International Geophysical Year – or, to be exact, the International Geophysical Year and a Half  (it ran from 1 July 1957 to 31 December 1958) – was an international collaboration that encompassed 67 countries and included such moments as the launch of Sputnik 1, and long-lasting impacts such as the drafting  of the Antarctic Treaty.
