''Hardtmuth is in some encyclopedies stamped as the inventor of the nowaday pencil. It is true, that he, as a man connected with manufacture of ceramics (he had a factory for the production of ceramics), found out how to simple make the inside of a pencil in the way the ceramics is produced. He pressed the atificial insides made from clay, powder graphite, soot and organic vehicle. With the different volume of clay and different degree of the burning out he got the insides of different hardness (the hardness is marked with numbers or letters). Josef Hardtmuth gained a patent for his discovery. He laid the foundations of the industrial pencil-production with the technology of graphite insides, which hasn´t been went better untill now.
The pencils were manufactured in a Wienna ceramic factory J. Hardtmuth. The production was gradually increasing, so that the pencils have been the main production programm since the 30´s of the last century. Therefore the followers of Josef Hardtmuth –Lewis and Charles Hardtmuth built up a new factory in Ceské Budejovice (L. & C. Hardtmuth) and in 1848 they started the manufacture of pencils and ceramics. The choice of this place appeared as a very advantageous one (the accessability of the main raw materials, good locality on the trace of the first railway in Europe, cheap labour force). And so the factory could specialize only on the production of pencils and other stationery.''
