Friedrich Gottlob Keller (born June 27, 1816 in Hainichen, Saxony – died September 8, 1895 in Krippen, Saxony) was a German machinist and inventor, who (at the same time as Charles Fenerty) invented the wood pulp process for use in papermaking.
He is widely known for his wood-cut machine (used for extracting the fibres needed for pulping wood).
Unlike Charles Fenerty, F.G.
Keller took out a patent for his wood-cut invention.
