Despite the huge number of publications about V.I. Lenin, many facts from his life and the life of the Ulyanov family remain little known, and many well-known materials are deliberately rewritten from the point of view of opportunistic political goals. In this book, the staff of the V.I. Lenin Memorial Museum tried to answer some of the questions most often asked by visitors to the V.I. Lenin Museum, as well as by authors of letters to the museum. It seems that the answers of people professionally involved in studying the life and work of V.I. Lenin may be of interest to all those interested in the history of our Fatherland.
