Query: excellent portrayal

Amos Elon has taken a major figure in Jewish life from the past couple of centuries and given him dimension. Elon, originally from the same German-speaking milieu as Herzl, was able to give insight to both a charismatic yet obscure persona; also, his knowledge of German allowed him to read primary documents in the original. But, primarily, this is a book and Elon is a good writer, and when the subject matter is one who he clearly has utmost respect for, the result is a biography which is an achievement.
