Isaac Deutscher said this quote

For nearly thirty years the powerful propaganda machines of Stalinism worked furiously to expunge Trotsky's name from the annals of the revolution, or to leave it there only as the synonym for arch-traitor. To the present Soviet generation, and not only to it, Trotsky's life-story is already like an ancient Egyptian sepulchre which is known to have contained the body of a great man and the record, engraved in gold, of his deeds; but tomb-robbers and ghouls have plundered and left it so empty and desolate that no trace is found of the record it once contained. The work of the tomb-robbers has, in this present instance, been so persistent that it has strongly affected the views even of independent Western historians and scholars.
