It's July Fourth -- a good time take a moment to thank the heroes who made our nation a reality. Washington, Jefferson, Franklin, Hamilton. Those names are always at the top of the list. But this year, let's thank another patriot who had a huge impact on the success of the American Revolution: Hercules Mulligan.

What makes Hercules Mulligan worthy of remembrance? 

Aside from being a daring activist and spy throughout the Revolutionary War, Mulligan saved George Washington's life-twice! He also converted Alexander Hamilton from a supporter of British colonial rule to a firebrand for the cause of independence. Not bad for a roly-poly Irish haberdasher.

Born in County Antrim, Ireland, in 1740, Mulligan moved to New York City with his family when he was six. After attending Kings College, the forerunner of Columbia University, Mulligan decided to become a tailor. It was a career choice that would reward him handsomely-and place him in a position to become an important player in the struggle for freedom.
