Daniel Leonard was the son of a prominent family in the ironworks industry. He lived in Taunton, Massachusetts until shortly after he accepted a position working for the Royal Governor of the state, at which point he became unpopular enough that he was forced to move to Boston, which was under British occupation at the time.

It makes sense, then, that Leonard put pen to paper and wrote essays to be published in the Boston Gazette under the pen name “Massachusettensis.” (What doesn’t make sense, 250 years later, is why he chose such a peculiar name. At least, not to us.) He began writing these pieces in December 1774 but it was the one published on this day in 1775 that finally set John Adams to writing replies under a pen name of his own. This back-and-forth continued for about three months, until a major event escalated the tensions between the Crown and the Colonies to the point where the exchange of essays became moot.
