The company is considered the main producer of Hanau silver. During the 19th Century Hanau became famous for its silversmith workshops producing excellent copies of antique silver in historical styles.

Johann Daniel Schleissner, son of a goldsmith in Augsburg, moved to Hanau in 1816 and the following year he opened his own company. He produced items in the Augsburg style and sold them internationally, especially in Russia, France and Near East.
