Sir William Pepperrell, 1st Baronet (27 June 1696 – 6 July 1759) was a merchant and soldier in Colonial Massachusetts. He is widely remembered for organizing, financing, and leading the 1745 expedition that captured the French garrison at Fortress Louisbourg during King George's War. During his day Pepperrell was called "the hero of Louisburg," a victory celebrated in the name of Louisburg Square in Boston's Beacon Hill neighborhood. He is the great-great-great grandfather of actor Robert Hardy.
