Faber-Castell was founded in 1761 at Stein near Nuremberg by cabinet maker Kaspar FABER (1730–84) as the A.W. Faber Company, and has remained in the FABER family for eight generations It opened branches in New York (1849), London (1851), Paris (1855), and expanded to Vienna (1872) and St. Petersburg (1874). It opened a factory in Geroldsgrün where slide rules were produced. It expanded internationally and launched new products under Kaspar FABER's ambitious great-grandson, Lothar (1817–96). In 1900, after the marriage of Lothar's granddaughter with a count of CASTELL, the A.W. Faber enterprise took the name of FABER-CASTELL and a new logo, combining the FABER motto, since 1761, with the "jousting knights" of the CASTELLs' coat-of-arms. A.W. Faber is the oldest brand-name pencil continuously sold in the US since 1870. Today Faber-Castell is one of the world's largest and oldest manufacturers of pens, pencils, other office supplies (e.g., staplers, slide rules, erasers, rulers) and art supplies, as well as high-end writing instruments and luxury leather goods.
