In the 19th century, Lehrte was the main junction for rail roads going North, South, East and West and was the main railway station for connections to Berlin.
Directly beside the Lehrte railway station in 1888, the chemist, Constantin Leonhardt, and the pharmacist, Johannes Heinrich Martini, founded the company "Leonhardt & Martini". It was renamed "Chemische Fabrik Lehrte" in 1926.

Right from the beginning, the founders of our company started with the production of important ingredients for the food industry and excipients for the pharmaceutical industry.

Milestones and ownership through three centuries:

When Merck KGaA took a strategic decision in 2013 to shed itself of small companies within the group and announced the closure of CFL despite its profitability, a privately-owned company from Saxony-Anhalt in Eastern Germany and raw material supplier to CFL, decided to buy the Lehrte site. Therefore, following forty years of administration within a global corporation, the summer of 2014 marks the restart of CFL as an owner-managed company under the enterprising leadership of Sebastian Reichenbach and Daniel F. Schüssler, allowing for a customer and solution oriented management.
