QUALITY SINCE 1790
The court princely architect Joseph Hardtmuth laid down the foundations of the company in 1790, from which his descendants, especially his son Carl and grandson Franz, have created one of the world’s largest companies in its field.
A number of significant innovations in the field of writing instruments comes from the KOH-I-NOOR HARDTMUTH factory. For example, the production of graphite and clay pencil lead, patented as early as 1802, the principle of machine-made pencils or division of graphite pencils into individual grades 8B-10H, according to the hardness of the lead, which were soon taken over by other manufacturers as a global standard.
KOH-I-NOOR HARDTMUTH also has several achievements. In 1900, the iconic yellow pencil 1500 won the prestigious award at Grand Prix in Paris and became the most famous pencil in the world.
