"Six great biologists 'come to life' in this book, based on the unique zoology lectures of professor Richard Eakin, University of California, Berkeley. Several times in the course of a year, Eakin--costumed, in make-up, and with props--appears before his students as a 'guest lecturer' and delivers a dramatic impersonation of one of the great biologists. His repertoire includes Harvey, Beaumont, Spemann, Mandel, Pasteur, and Darwin, and his impersonations bear the stamp of careful research into both the personality and background of each character. . . .Great Scientists Speak Again contains all six lectures. Each is preceded by an introduction giving references for the characterization. A readable and inspiring little book." --Science Teacher "A delightful and refreshing book which skillfully presents a well worn subject in an original and enjoyable way." --Yankee Book Peddler
