An intellectual biography -- for intellectuals. It lacks the emotional and dramatic appeal of the Merejkowski, the warmth and color of the Taylor biography. But it is interesting and artists, scholars and engineers will find it absorbing, for the author has approached each facet of that complex character with scientific precision. The intellectual will like this analysis of one man's genius; the people who enjoy history for its own sake will like the full background; but the average reader will feel it too detached and objective and intangible. A scholarly and careful study.
