If you were asked, who is the man once called "the greatest incendiary in all of America" and one of the earliest activists in the Revolution, chances are you may not give the right answer.
According to historian Christian Di Spigna, the answer is Dr. Joseph Warren. He laid the groundwork for American independence, at a time when many colonists were opposed to armed rebellion. But Warren was martyred at Bunker Hill, and today his story is largely forgotten.
Di Spigna will be speaking at the New England Historic Genealogical Society on December 12.
Christian Di Spigna is the author of the new book, "Founding Martyr: The Life And Death Of Dr. Joseph Warren, The American Revolution's Lost Hero." He tweets @Martyr1776.
