Soviet literature has published many materials on the history of the discovery of wireless communications and the works of A. S. Popov. However, his life and works, as well as the conditions in which A. S. Popov lived, continue to be studied, and more and more aspects of his activity are revealed. The author of the new biography A. S. Popova M. I. Ra- dovsky has been dealing with this topic for a number of years. Currently, he has the opportunity to systematize the accumulated material based on primary sources and offer it to readers in the form of an extended monograph.
