The study of the processes of interaction of electron beam with electromagnetic fields and devices based on them was and remains one of the central directions of the science of vibrations and waves. In the 20th century, reviews devoted to the theory and description of new devices at that time were published in the journal "UFN". Years passed, changing the theory and design of these devices, and their place in the range of electromagnetic waves. Relativistic electronics has appeared. The development of the terahertz range is underway. Over the past years, some new facts related to the history of the creation of a traveling-wave tube (TWT) have become known, covered in this article. The facts of the creative way of Andrei Haeff, Rudolf Kompfner and John Pierce are stated. In addition to the history of the TWT in the faces and the fortunes it has been considered the results of some of the modern research and development of the TWT for various purposes.
