The history of Mono began long before 1959. Over 125 years ago.

In 1895 Wilhelm Seibel I laid the foundation stone for the family business with the founding of the Britaniawarenfabrik W. Seibel in Mettmann in North Rhine-Westphalia. Expansion followed in 1911 with a branch factory in Ziegenhain in Hesse, which later became the property of his two younger sons Heinrich and Alfred Seibel.

Due to the good order situation in the post-war years, the workforce of the two plants in Mettmann and Ziegenhain grew to almost 1000 employees. But in the 1950s the company felt the effects of competition, especially from Japan and Spain. The sales figures fell, employees had to be laid off, the Mettmanner company initially merged before it was dissolved.

In Ziegenhain, Herbert Seibel (Heinrich Seibel's eldest son) tried to take countermeasures and commissioned Peter Raacke to develop a new cutlery. Mono A came onto the market, founded the Mono brand and secured the existence of the family business as a manufactory through a strategic focus on quality and design.

In 1985 Herbert Seibel retired at the age of 75 and his nephew Wilhelm Seibel IV, a great-grandson of the founding father, took over the business. At the end of the 80s he led the flatware production back to Mettmann.

Today, Wilhelm Seibel V. runs the family business with his sons Johannes and Matthias, the fifth and sixth generations, with around 30 employees.
