Isaac Sears was an American merchant, sailor, Freemason, and political figure who played an important role in the American Revolution. Sears and his fellow Sons of Liberty all gathered at a coffee house on October 31, 1765, the day before the Stamp Act was to take effect. They ultimately resolved to enforce the opposition to the distribution of the stamps and formed an association to stop the importation of British goods until the act was rescinded. Sears organized and was a known leader of the Sons of Liberty in 1765.
