They knew that the transfer methods then available to Blake did not work in relief etching, so they had him invent a method perfectly analogous to the one Senefelder invented for lithography—ten years later.    From Wordnik.com.  [Introduction] Reference

It seems that Senefelder finally became thoroughly disheartened about his etched copper plates, mainly owing to the great expense and labor connected with their production, and was about to discontinue his efforts when the idea occurred to him to experiment with the stone which he had used as an ink slab for so many months, treating it in the same manner as the copper plates.    From Wordnik.com.  [The Building of a Book A Series of Practical Articles Written by Experts in the Various Departments of Book Making and Distributing] Reference

It is not surprising, therefore, that a man of such persistence and capability as Senefelder should eventually discover the best method for drawing and printing from stone; for it is a fact that, since he perfected his invention, more than a hundred years ago, it has been hardly possible to improve on his methods, so completely did he cover the entire field of manipulation in this direction.    From Wordnik.com.  [The Building of a Book A Series of Practical Articles Written by Experts in the Various Departments of Book Making and Distributing] Reference

Senefelder, who was in so little repute as an author and artist, that printers and engravers refused to publish his works at their own charges, and so set him upon some plan for doing without their aid.    From Wordnik.com.  [The Paris Sketch Book] Reference

Lithography was well known in Germany, by the very name which it still bears, nearly three hundred years before Senefelder reinvented it; and specimens of the ancient art are yet to be seen in the Royal Museum at Munich.    From Wordnik.com.  [Industrial Biography]
