Crane remains the predominant supplier of paper for use in U.S. currency (Federal Reserve Notes). </P> <P> Stephen Crane was the first in the Crane family to become a papermaker, buying his first mill, "The Liberty Paper Mill", in 1770 . He sold currency - type paper to engraver Paul Revere, who printed the American Colonies' first paper money . In 1801, Crane was founded by Zenas Crane, Henry Wiswall and John Willard . The company's original mill had a daily output of 20 posts (1 post = 125 sheets). Shortly after, in 1806, Crane began printing currency on cotton paper for local, as well as regional, banks, before officially printing for the government . Crane developed a method to embed parallel silk threads in banknote paper to denominate notes and deter counterfeiting in 1844 . </P>
