Justus Claproth (1728 - 1805) was a German jurist, or teacher of law, and inventor of the deinking process of recycled paper. Before the invention of the paper machine in 1799 the most common fibre source was recycled fibres from used textiles. The rags were from hemp, linen and cotton. It was not until the introduction of wood pulp in 1843 that paper production were independent of recycled materials. The process for removing printing inks from recycled paper was invented by Justus Claproth in 1774. He practiced together with German paper producer Johann Engelhard Schmid. Today this method is called deinking.
