Montblanc International GmbH is a German manufacturer of writing instruments, watches and accessories, often identified by their "White Star" logo.
Founded by the stationer Claus-Johannes Voss, the banker Alfred Nehemias and the engineer August Eberstein in 1908, the company began as the Simplo Filler Pen company producing up-market pens in the Schanzen district of Hamburg. Their first model was the Rouge Et Noir in 1909 followed in 1910 by the pen that was later to give the company its new name, Montblanc. The first pen (a fountain pen) known as the Meisterstück (English: "Masterpiece," the name used for export) was produced in 1924. Today Montblanc brand is on other goods besides pens, including watches, jewel, fragrance, leather goods and eyewear.
The company was successful despite its founder, Eberstein, fleeing to the US to avoid prosecution for stealing company funds in 1909. In 1934 the company changed its name to Montblanc-Simplo GmbH, and introduced its first piston filler.
