Hymen L. Lipman (March 20, 1817 – November 4, 1893) is credited with registering the first patent for a pencil with an attached eraser on March 30, 1858 (). Hymen L. Lipman was born March 20, 1817, in Kingston, Jamaica, to English parents. He emigrated to the United States around 1829 with them, arriving in Philadelphia, Pa., where he resided for the remainder of his life. In 1840, Lipman succeeded Samuel M. Stewart, then the leading stationer in Philadelphia. Three years later, he started the first envelope company in the U.S. In 1848, he was married to Mary A. Lehman, daughter of Peter Lehman, one of the founders of the Philadelphia College of Pharmacy. They had a son and two daughters. In 1862, Lipman sold his patent to Joseph Reckendorfer for $100,000, who went to sue the pencil manufacturer Faber for infringement.〔Petroski, Henry (1990).

ISBN 0-394-57422-2; ISBN 0-679-73415-5, page 171〕 In 1875 the Supreme Court of the United States ruled against Reckendorfer declaring the patent invalid because his invention was actually a combination of two already known things with no new use.〔http://supreme.justia.com/us/92/347/case.html Reckendorfer v.
