Friedrich Gottlob Keller (born June 27, 1816 in Hainichen, Saxony – died September 8, 1895 in Krippen, Saxony) was a German machinist and inventor, who 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). Before wood pulp became widely available paper was made from rags.
