Ask a plain question — movements, influence, education, exhibitions, holdings, peers. Every answer carries its provenance.
Ludwig von Siegen was a German soldier and amateur engraver, who invented the printmaking technique of mezzotint, a printing-process reliant on mechanical pressure used to print more complex engravings than previously possible. He was a well-educated aristocrat, and a Lieutenant-Colonel who commanded the personal guard of William VI, Landgrave of Hesse-Kassel, and acted as a personal aide to the ruler, with the title kammerjunker or Chamberlain.
