Today in Legal History: Carbon Paper Patented in London
Carbon paper was patented in London on Oct. 7, 1806. While it may be difficult to visualize in this age of electronic copies and photocopy machines, at one time if you wanted a copy of something, you hand printed it yourself. With the creation of carbon paper, used in conjunction with a typewriter, multiple copies could be made at one time. Although carbon paper (and its progeny, carbonless paper) has lost much of its market due to photocopiers and the ease of printing multiple copies, it is still used for manual credit card receipts, tickets, and duplicate checks. It is also memorialized in “cc” for emails (cc is short for carbon copy).
