This momentous biography tells the story of the Huxleys: the Victorian natural historian T. H. Huxley ("Darwin's Bulldog") and his grandson, the scientist, conservationist, and zoologist Julian Huxley. Between them, they communicated to the world the great modern story of the theory of evolution by natural selection. In The Huxleys, celebrated historian Alison Bashford writes about these omnivorous intellects together, almost as if they were a single man whose long, vital life bookended the colossal shifts in world history from the age of sail to the Space Age, and from colonial wars to world wars to the cold war.

The Huxleys' specialty was evolution in all its forms—at the grandest level of species, deep time, the Earth, and at the most personal and intimate. They illuminated the problems and wonders of the modern world and they fundamentally shaped how we see ourselves.

But perhaps their greatest subject was themselves. Bashford's engaging, brilliantly ambitious book interweaves the Huxleys' momentous public achievements with their private triumphs and tragedies. The result is the history of a family, but also a history of humanity grappling with its place in nature. This book shows how much we owe—for better or worse—to the unceasing curiosity, self-absorption, and enthusiasms of a small, strange group of men and women.
