Until the publication of this book in 1974, the leaders of the October Revolution remained very badly known. This book exhumes the autobiographies written by the men whose actions and ideas have moulded events. Unique as sources of documentation on the Bolsheviks, these autobiographies, encompassing personal and political information up to 1917 add an important historical dimension. They allow the reader to appreciate more accurately the role played by each of the protagonists in preparing and carrying out the Revolution and beyond this they put the Bolsheviks of 1917 in the context of their social milieu and of the circumstances that shaped their minds.
