Since 1983 - the WESSLING family business

In 1983 Dr Erwin Weßling laid the foundation stone for the company in Altenberge and wrote the first chapter in its success story.

One generation later, the story is still being told as Julia, Florian, Anna and Diana Weßling lead the international WESSLING Group and its 1,200 employees into the future.

A restored windmill in the heart of the Münsterland dating back to the 18th century was the site Dr Erwin Weßling chose for the first chemical laboratory in the life of the young company. WESSLING then went on to set up one site after another throughout Germany – and in international locations from 1992 onwards. 40 years after its foundation, the group has sites at 22 locations in Europe and China.

As the company continues to grow, it still abides by its principles. WESSLING remains true to the name it made for itself in the beginning, enjoying an enviable reputation for consultancy based on engineering and scientific expertise geared to the specific requirements of the customers and known for its precise analysis methods and test results.
