David H. DeVorkin (1944- ) is a curator in the National Air and Space Museum's Space History Department. This collection of photographs was compiled by DeVorkin while researching for his 1992 book, 'Science with a Vengeance', which documents early rocket technology from the 1940s onwards. This book traces the exploration of the upper atmosphere with ballistic missiles systems, particularly the V-2. The first part of the book deals with the military context of upper atmospheric research: the military interest in seeing that such work was being done, the formation of appropriate groups in military labs capable of doing the work, and the development of the technical and managerial infrastructure requred to get the work done. The later half of the book examines the specific problems each scientific group addressed, including the technical, professional and managerial obstacles they faced as they explored the use of rockets for studying the sun, cosmic rays, the upper atmosphere, and the ionosphere.
