The idea of writing a historical paper is new to me. All I can hope to do is to give my own subjective slant, as I saw things develop in the period from 1938, when I first became interested in geophysics, to 1965, when I left the field to work in remote sensing (in which I have been engaged ever since). When I talk about geophysics, from which I have been away for so long, I feel like Rip Van Winkle, who fell asleep for 20 years.
