James Van Allen : the first eight billion miles by Abigail Foerstner

"A distinct contribution, long overdue, this most satisfying biography sets the subject within the context of his time, place, and profession. It not only illuminates the early history of space science but addresses the larger history of the scientific enterprise and even American history. The scientific basics and the open questions and controversies with which Van Allen was involved are well articulated, and the contextual look at the birth of space science will be useful to scientists."—Tom Crouch
