First published in 1892, this autobiography of the great naturalist, compiled and edited by his son Francis, offers fascinating glimpses into the mind and personal experiences of the man whose discoveries have had such a profound influence on science, philosophy, and the modern world view. In the first half of the book Darwin reminisces about his early life, his family and upbringing, and his five-year voyage on the HMS Beagle, during which he made the many observations that were later to prove so critical to his formulation of evolutionary theory. The second half is devoted mainly to the Origin of Species: its foundations, development, the writing and publication process, its varied critical reception, and the gradual acceptance and growth of evolutionary theory. Also included are thoughts on his lesser-known work in geology and the fertilization of flowers, plus a selection of his letters. This autobiography is a an intriguing behind-the-scenes look into the personal life of a great scientist and the development of one of the most powerful ideas of the modern era.
