Eberhard Faber's company made pencils and other office supplies in New York City from 1861 until 1956, when manufacturing moved to Wilkes-Barre, Pa. A. W. Faber-Castell acquired the company in 1987.
According to the accession file, at the National Museum of Natural History Charles Louis Pollard was an assistant curator of ferns from 1895 to 1903, William R. Maxon was the curator of plants from 1899 to 1946, and Conrad V. Morton was a curator of ferns from 1926 to 1972. All three men presumably used this ruler in their research.
