"This book represents an effort to collect together with reasonable orderliness the minimum amount of theoretical material necessary for a good understanding of electron flow and electron focusing in devices other than electron microscopes and image tubes...there is more emphasis and more material on space charge and thermal velocities than is usual in books on electron optics."
"John Robinson Pierce made many important contributions to microwave and communications technology during his long career at Bell Laboratories. He also made important contributions to the development of microwave electron tubes such as the traveling-wave tube. Pierce is also remembered for naming an amplifying device developed by some of his Bell Labs colleagues the transistor. Finally, in the late 1950s, Pierce was an early and enthusiastic promoter of communications satellites and played a pivotal role in the development of two of the earliest, Echo I and Telstar." (from IEEE site bio).
"In 1975, [Pierce] received the IEEE Medal of Honor for 'his pioneering concrete proposals and the realization of satellite communication experiments, and for contributions in theory and design of traveling wave tubes and in electron beam optics essential to this success.'" (wiki)
