Joseph Warren, a Founding Father of the United States, was an American physician who was one of the most important figures in the Patriot movement in Boston during the early days of the American Revolution, eventually serving as President of the revolutionary Massachusetts Provincial Congress. Warren enlisted Paul Revere and William Dawes on April 18, 1775, to leave Boston and spread the alarm that the British garrison in Boston was setting out to raid the town of Concord and arrest rebel leaders John Hancock and Samuel Adams. Warren participated in the Battles of Lexington and Concord the following day, the opening engagements of the American Revolutionary War.

Samuel Adams was an American statesman, political philosopher, and a Founding Father of the United States. He was a politician in colonial Massachusetts, a leader of the movement that became the American Revolution, a signer of the Declaration of Independence and other founding documents, and one of the architects of the principles of American republicanism that shaped the political culture of the United States. He was a second cousin to his fellow Founding Father, President John Adams.
