Response to a survey of approximately 250 leading geophysicists worldwide, conducted by the American Institute of Physics (AIP) Center for History of Physics and the Committee on History of Geophysics of the American Geophysical Union in 1997. 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. Contents include biographical statement from Who's Who 48th Edition, brief answers to Parts One and Two of Questionnaire, and a bound unpublished biography compiled by Carol Alldredge Beebe (daughter) dated 1988, taken mostly from Leroy Alldredge's journals, scrapbooks, previous autobiographical statements, taped interviews, and conversations; includes a list of publications. It covers personal and professional aspects of his life: childhood, family, education, jobs, travel and religious activities. Alldredge's wartime employment in the Naval Ordnance Laboratory led to his graduate education and work in geomagnetism.
