AINMULLER, MAXIMILIAN EMMANUEL (1807 1870), German artist and glass-painter, was born at Munich on Feb. 14, 1807. In 1828 he was appointed director of the newly founded royal painted-glass manufactory at Munich. The method which he gradually perfected there was a development of the enamel process adopted in the Renaissance, and consisted in actually painting the design upon the glass, which was subjected, as each colour was laid on, to carefully-adjusted heating. The earliest specimens of Ainmiiller's work are to be found in the cathedral of Ratisbon. With a few exceptions, all the windows in Glasgow cathedral are from his hand. Specimens may also be seen in St. Paul's cathedral, and Peterhouse, Cambridge, and Cologne cathedral contains some of his finest productions. Ain muller had considerable skill as an oil-painter, especially in interiors. He died on Dec. 9, 1870.
