Letter to Spencer Weart, director of AIP Center for History of Physics; six pages of curriculum vitae and publications; and the questionnaire with brief, handwritten responses. Recipients were asked to send copies of their curriculum vitae and a list of publications as part one of the survey and were then asked to discuss their entry into science in general and geophysics specifically as a career; how their scientific achievements came about and major efforts they were involved in which did not achieve the hoped for results; changes from one discipline to another; funding sources; the role of other disciplines in their own research; their work as educators; and their involvement in geophysics related institutions.
