Forever famous for his outsized signature on the Declaration of Independence, John Hancock was a larger than life figure in other ways as well. Part of the great Boston triumvirate that included Samuel Adams and James Otis, Hancock was a wealthy merchant whose bank account helped to finance the radical activities of the Sons of Liberty. Hancock himself became a thorn in the side of the British, who seized his ship, the Liberty, in 1768 and put a price on his head in 1775.
