This is the extraordinary true story of America's first female rocket scientist, told by her son. It describes Mary Sherman Morgan's crucial contribution to launching America's first satellite and the author's labyrinthine journey to uncover his mother's lost legacy - a legacy buried deep under a lifetime of secrets political, technological, and personal. Blending a fascinating personal history with dramatic historical events taking place on the world stage, this compelling narrative brings long-overdue attention to a modest but brilliant woman whose work proved essential for America's early space program. In 1938, a young German rocket enthusiast named Wernher von Braun had dreams of building a rocket that could fly him to the moon. On the opposite side of the world, a young farm girl named Mary Sherman was attending high school in Ray, North Dakota. In an age when girls rarely dreamed of a career in science, Mary wanted to be a chemist. A decade later the dreams of these two disparate individuals would coalesce in ways neither could have imagined. In a vivid narrative, Morgan relates how World War II and the Cold War space race with the Russians changed the fates of both von Braun and his mother. When von Braun and other top engineers could not find a solution to the repeated failures that plagued the nascent US rocket program, North American Aviation, where Mary Sherman Morgan then worked, was given the challenge. Recognizing her talent for chemistry, company management turned the assignment over to young Mary. In the end, America succeeded in launching rockets into space, but only because of the joint efforts of the brilliant farm girl from North Dakota and the famous German scientist. While von Braun went on to become a high-profile figure in NASA's manned space flight, Mary Sherman Morgan and her contributions fell into obscurity.
