From 1960 to 1964, I was an undergraduate student at the California Institute of Technology [Caltech] in Pasadena, California. During these years, I spent much of my time indulging in student body politics and playing intercollegiate football. However, with the encouragement of a number of faculty in the Division of Geological Sciences [not yet GPS], I saw the light and became a geology major [strictly speaking, geophysics]. This paper is an expansion of a talk I presented at the 90 th Anniversary of the Division of Geological and Planetary Sciences in 2017.
