SuperDARN founder Ray Greenwald has published the first of a planned 3-part series on the history of SuperDARN in the journal 'History of Geo- and Space Sciences'. The paper covers the pre-SuperDARN era from experiments using HF coherent radar in Alaska with Jean-Paul Villain through the construction of radars at Goose Bay, Schefferville, and Halley Station and the development of techniques critical to the development of SuperDARN. The article is available for download from the site 'SuperDARN+https://hgss.copernicus.org/articles/12/77/2021/'

Ray dedicated this history to the memory of three SuperDARN pioneers who made significant contributions that demonstrated the value of HF radar measurements of the ionosphere and magnetosphere, particularly at high latitudes. They are John C. Samson, Jean-Paul Villain, and A. David M. Walker.

Congratulations, Ray! We look forward to the next installment.
