Marie Mathias Nicolas Louis Danzas, a lieutenant in Napoleon's Grande Armée, enters into the shipping and transport business after the battle of Waterloo. The company in the French Alsace region would soon bear his name and play an active role in the development of rail travel and steam navigation in the 19th century. In 1854, the first consolidated shipments were offered on the Zurich-Basel/St. Louis route.

Danzas assumes responsibility for international mail on behalf of the Swiss PTT in 1884. Delivery within 24 hours was guaranteed for the route between Switzerland and England.  

Danzas became a part of Deutsche Post in 1999.
