International Polar Year

The International Polar Year (or IPY) was a collaborative, international effort researching the polar regions.  Karl Weyprecht, an Austro-Hungarian navy officer, motivated the endeavor, but died before it first occurred in 1882-1883. Fifty years later (1932-1933) a second IPY occurred. The International Geophysical Year was inspired by the IPY and occurred 75 years after the first IPY (1957-58).
