A member of the distinguished British Huxley family, Julian Huxley (1887-1975) was a man of many talents and enormous energy. At the beginning of his career, he founded the biology department at Rice Institute, where he taught for three years before going on to achieve eminence as a biologist, statesman, and intellectual. While this volume concentrates on Huxley's contributions to field and laboratory biology, when first published in 1992, it also provided the first in-depth examination of his efforts to popularize science and to advance the human species through eugenics. Julian Huxley also encourages consideration of Huxley's religious and social views and his public role in science. C.
