The story

The company was founded in 1856 by Diedrich Leonardt to manufacture dip pens. After two large expansions led by Leonardt in 1863 and 1867, D Leonardt & Co. developed large export market in South America and Eastern Europe, and produced pens for the King of Italy. The manufactured pens were considered to be of high quality and included their famous patent ballpoint pens, such as the "Automatic Wonder Pen", a new type of fountain pen introduced in 1871.

Despite most manufacturers of nibs established in Birmingham having since closed their factories, Leonardt & Co. is one of the few companies that have remained in the industry since its founding, although the company ceased to produce pens.

The Leonardt brand is currently produced by the Manuscript Pen Company, established in 1980. and based in Highley

The only other British company that currently manufactures dip pens is William Mitchell (Calligraphy) through its brands Joseph Gillott's and William Mitchell.
