Scientists may take exception to this light-hearted biography of a dramatic figure, the leading authority on ""physical optics"". But whatever the value of this book as a survey of his work, it has a definite value as a career book with an inspirational character for any boy interested in the field of science. Dr. Wood, genius, showman, practical joker -- and scientist -- makes ideal material for Seabrook, and in the course of his life, Dr. Wood has made signal contributions to civilization.
