This is Part 2 of an exploration of the live of the most productive people in history. We will look at the life, times, and work habits of medieval philosopher Thomas Aquinas (the most prolific writer before the invention of the word processor), composer Georg Philipp Telemann (who produced thousands of music compositions), sci-fi writer Isaac Asimov (who wrote 500 books in nine out of the 10 major categories of the Dewey Decimal System) and Thomas Edison, who had over 1,000 patents to his name.
