Andreas Eigner (1801–1870), who was born at Diedldorf, Upper Palatinate, distinguished himself as a painter and a restorer of old pictures.
He successfully employed alcoholic vapours, and a varnish of his own invention, to protect paintings against the destructive influence of the atmosphere.
He was chiefly employed in the Galleries of Munich, Augsburg, Stuttgart, Carlsruhe, Basle, and Solothurn.
