The Christmas Lecture is presented in the tradition of the great British scientist Michael Faraday (1791-1867), who began presenting his annual Christmas lectures for children and their families at the Royal Institution of Great Britain in the 1840s. A collection of these lectures on the chemical history of a candle can be found online here, thanks to Project Gutenberg. You can also find more of his writings online by searching for "Michael Faraday" on Google Books.
