I picked this up at ConFusion and it is an apparently complete history of private liquid fuel rocketry up to the last launch of Robert Goddard. It also describes some significant solid fuel rockets as well. The main players are Goddard and the Germans including Von Braun with coverage of what was happening in the Soviet Union as well. Written by Michigan fan Peter Alway and published in Ann Arbor. I found it interesting to read and fill in the gaps about what was happening before liquid fueled rocketry became a government backed phenomenon.
