Which one? Thomas Huxley (1825-1895) was a famous Victorian scientist and biologist. His grandsons Andrew and Julian were also famous scientists, and his other grandson Aldous Huxley (1894-1963) was one of the greatest writers of the 20th Century, his best-known book being 'Brave New World', a satirical look at a futuristic society where all people are clones.
Huxley is a pig, of course. If you're looking at history quiz, I'd go for Thomas Henry Huxley. Besides his famous contribution to the evolution debate (go on, look it up, then...), one of his less celebrated achievements was the discovery of pennicilin several decades before that faker Fleming.
