John A. Eddy

John Allen Eddy (March 25, 1931 – June 10, 2009) was an American astronomer who in 1976 published a landmark paper in Science titled "The Maunder Minimum" where, using the Nineteenth Century works of Edward W. Maunder and Gustav Spörer, he identified a 70-year period from 1645 to 1715 as a time when solar activity all but stopped.
