Thomas Henry Huxley (May 4, 1825 - June 29, 1895)
According to Wikipedia, Huxley "was an English biologist, known as 'Darwin's Bulldog' for his advocacy of Charles Darwin's theory of evolution....
"Huxley's famous 1860 debate with the Lord Bishop of Oxford, Samuel Wilberforce, was a key moment in the wider acceptance of evolution, and in his own career. Wilberforce was coached by Richard Owen, against whom Huxley also debated on whether man was closely related to apes..... He was instrumental in developing scientific education in Britain, and fought against the more extreme versions of religious tradition.
"Huxley used the term 'agnostic' to describe his own views on religion, a term whose use has continued to the present day, and which throws light on his demanding criteria for proof in science."
