In 1978, Arthur Blank and his business partner Bernie Marcus were running a successful chain of hardware stores called Handy Dan – but then, they were unexpectedly fired. The next year, they conceived and launched a new kind of home improvement store that flopped on opening day, but went on to become one of the biggest private employers in the U.S. The Home Depot now earns annual revenue of almost $100 billion.
