<noinclude></noinclude>[[Hardtmuth]] (or ''"L & C Hardtmuth"''), more commonly known as ''"[[Koh-i-Noor]] Hardtmudt"'', is a historic producer of pencils and office supplies that was founded in [[1790]] by ''Joseph Hardtmudt'', which in [[1802]] patented the first pencil made of clay and coal. Born in the Austro-Hungarian Empire, the company was transferred from the sons of the founder from Vienna to České Budějovice, currently in the Czech Republic. The company introduced in [[1889]] the line of pencils ''"Koh-i-Noor"'', called by the same name of the famous diamond to magnify their quality. To distinguish them, they were painted in yellow, a color that from then has become a classic for pencils.

Il nome ''Koh-i-Noor'' è diventato il marchio distintivo dell'azienda che era con la [[Faber Castell]] uno dei principali produttori europei di matite ed è ancora sul mercato nel campo degli articoli da cancelleria e da disegno. Non sono note fino ai tempi recenti produzioni proprie di penne stilografiche, ma l'azienda ha commercializzato in più casi penne prodotte da altri (in particolare commercializzava in Europa le [[Waterman]]), talvolta anche con marchio proprio.

The ''Koh-i-Noor'' brand became the hallmark of the company, that with [[Faber Castell]] was one of the leading European pencils producers and is still on the market in the field of stationery and drawing tools. It's not known until recent a production of fountain pens, but the company has marketed in more cases pens produced by others (particularly they marketed in Europe the [[Waterman]]'s), sometimes even with their own brand.
