I heard somewhere, long ago, that one of the main drivers behind Alexander Graham Bell's early inventions was to show the wealthy family of a woman he loved that he was not after their money and was perfectly capable of making his own. How many things we enjoy today are the product of similar motivations? Was fire harnessed 1000s of years ago by a man who wanted to keep his family safe & warm?
