Arthur M. Blank, co-founder of the Home Depot, was introduced to the startup life as a kid. His father launched a mail-order pharmacy business out of the one-bedroom apartment the family of four shared in the Sunnyside section of Queens, New York. Four years later, darkness set in when Blank’s father died suddenly. His mother picked up the pieces of both the family and the family business. She plowed ahead and became a successful entrepreneur, ultimately selling the company.
