Historical pictures from the past.

A family-owned company, strengthened by crises.

In the company’s history there have been many crises in which the management has withstood external influences. The company survived two world wars and the Great Depression of 1929. In 1965 Bad Karlshafen was hit by the Heinrich flood and afterwards various buildings were demolished, rebuilt and numerous employees were hired. In 2008, the bankruptcy of the Lehmann Brothers bank plunged the world into a severe economic crisis and many thousands of people lost their jobs. In 2020, COVID-19 will cause another global economic collapse but despite the pandemic, the company is well positioned for the future.
