On July 24th, 1788, the Chemical Factory Marktredwitz (CFM) was founded as the first chemical factory in Germany.

Around 100 years later, the Tropitzsch brothers acquired the company from the founder’s successors and intensified their research and development activities in the field of pesticides and other basic chemicals.

At the turn of the millennium, biotech experienced a real boom. Oskar Tropitzsch recognized the great market potential behind and in 2001, he founded Iris Biotech GmbH to strengthen the market position in the fields of peptide synthesis and life sciences in general. The company name thereby relates on one hand to the name of Oskar Tropitzsch’s daughter Iris, but on the other to nature, the plant “Iris” and the iris within the eye. Shortly after the foundation of the company, Dr. Thomas Bruckdorfer joined and brought in his scientific knowledge in peptide chemistry and the required market expertise to further develop the company successfully on long term.
