Charles Darwin

I recommend his first book, The Voyage of the Beagle.  It's a travelogue and natural history of his trip around the world on a survey ship.  Great reading, great history, don't miss it.

Charles Darwin was born in Shrewsbury, England on Feb. 12, 1809. His father was also a naturalist and a physician. His mother died when he was eight.  At age sixteen, Darwin left Shrewsbury to study medicine at University of Edinburgh . However, he did not continue in the studies because the sight of surgery performed without anesthesia repelled him.

Darwin studied to become a clergyman at attended Cambridge University. After graduation, he went on a five-year scientific expedition to the pacific coast of South America on the H.M.S. Beagle from 1831 - 1836. On the Origin of Species was published in 1859 describing evolution and natural selection and giving a theoretical explanation for the diversity among living and fossil beings. Darwin was among the first evolutionary biologists. His book was popular but also controversial among those who felt threatened at the notion that humans were descended from ape-like creatures.

Darwin married in 1839 and lived with his wife and children at their home on Downe, England. He was ill much of the time, but through discipline and family support was able to remain productive.  The identity of his illness is not known with certainty, but may have been Chagas disease contracted during his travels in South America. He died on April 19, 1882 and is buried at Westminster Abbey.

Darwin's main works include The Origin of Species and The Descent of Man. They were published in 1859 and 1871 respectively.

Roger Lewin, Ph.D. is a prize-winning author of 17 science books, including the acclaimed Complexity: Life at the Edge of Chaos. He speaks frequently at national conferences on complexity science and business. Lewin worked on the London staff of New Scientist for nine years and then for Science of Washington, D.C. for another nine years. Following his years of writing for these magazines, Lewin ventured off on his own and became a full-time free-lance writer in 1989 in order to concentrate on his books. Earlier, Lewin wrote several popular science books, including three with world-renowned anthropologist Richard Leakey. Intellectual like a wonderful storyteller, and yet highly accurate as a reporter, Lewin writes with both dedication and intrigue. In his book, Bones of Contention, Lewin analyzes only key events in the past century of paleoanthropology, focusing on important happenings. The book is more of a narration than that of a report, telling the story, invoking understanding. Lewin seems to enjoy enriching the reader with little known facts and interesting insights while he tells the story.
