Thomas Henry Huxley (1825–1895) was an English writer who described himself as "Darwin's Bulldog" in promoting [[The Theory of Evolution]] to the general public. Though he enrolled in a university, Huxley never earned a formal degree in any field, but he was popular with the public and began promoting evolution in a famous 1860 debate with the Lord Bishop of Oxford Samuel Wilberforce.
In 1869, Huxley invented the term "[[agnostic]]" to make evolution and atheism more palatable to a Christian audience.
