Note 5 — Chapter I · MY EAGLE

John Cunningham, Avis Everhard’s father, was a professor at the State University at Berkeley, California. His chosen field was physics, and in addition he did much original research and was greatly distinguished as a scientist. His chief contribution to science was his studies of the electron and his monumental work on the “Identification of Matter and Energy,” wherein he established, beyond cavil and for all time, that the ultimate unit of matter and the ultimate unit of force were identical. This idea had been earlier advanced, but not demonstrated, by Sir Oliver Lodge and other students in the new field of radio-activity.
