24 - Lithography stones by Kai Linke

The monument in Büsingpark commemorates Alois Senefelder's former place of work in Offenbach. He had developed the first chemical planographic printing process in Munich around 1798 and founded a print shop there.
After the Offenbach music publisher Johann Anton André (1775-1842) acquired the patent rights to this new printing technique in 1799, he brought Senefelder to Offenbach in the spring of 1800, as the inventor was to personally supervise the introduction of lithography in the publisher's music printing shop. The residential and commercial building with print shop was located on this site, at what was then Domstraße 21.
André's publishing production was gradually converted from tin and copper engraving to the faster and more cost-effective process of lithography.
Two brothers, Johann Anton André, brought the new printing process from the Offenbach headquarters to the music publisher's branches in Paris and London. The technique, which is considered the forerunner of offset printing, subsequently spread throughout the world.
