International Senefelder Foundation Marks Its 40th Anniversary

OFFENBACH, GERMANY—Nov. 4, 2011—Alois Senefelder did for image printing what Gutenberg did for letterpress printing, i.e. both inventors enabled a high-quality method of duplication. Senefelder developed lithography in 1797/98, around 350 years after Gutenberg invented the moveable type system used in book printing.
