Maunder Minimum
Eddy was laid off from the High Altitude Observatory at the National Center for Atmospheric Research (NCAR) in 1973 due to budget cutbacks and the poor performance reviews he earned due to his interdisciplinary forays, which were frowned upon at the time. He then was hired by NASA to write a book, which enabled him to travel east to do research in the great astronomy libraries, particularly at Harvard and the Naval Observatory, which he used to also do research on the Maunder Minimum. His work on this was published in the journal "Science" as a cover story. After publication, his former employers at the HAO tried to hire him back. The interest resulting from "The Maunder Minimum" paper saw him giving over 50 talks a year around the world about his work and history.
