1994: AGU's 75th Year


  • Thomas E. Graedel


In many ways, AGU's history since its founding in 1919 is also a chronicle of the history of geophysics. For example, when the theory of transient groundwater flow was published in 1935, it appeared in Eos, Transactions of the American Geophysical Union. When the magnetic seafloor stripes confirming the theory of plate tectonics were reported in 1965, it was done at an AGU meeting in Washington, D.C. When Apollo asronauts recovered Moon rocks in the 1970s, some of those astronauts were AGU members who reported on their journeys and scientific analyses at AGU meetings.
