Pasteur's life is most a propos for this distinguished series. It expresses in purest example the ideals and methods of the scientist. His was a life well suited to compact recital. The author sets forth a figure psychologically uncomplex, if amazing in acuity and intuition whose career was a succession of triumphs. Only the loss of a child marred his domestic tranquillity. A patient but unimpassioned toiler, pragmatic, Pasteur was humorless, proud of his discoveries but relatively free of vanity, unshakeably self-confident, gently sentimental and a patriot. The author, sole living descendant of Pasteur, writes with a simplicity and sympathy that are admirable.
