Hanns R. Neumann started to operate as a coffee broker under his own name in 1934 in Hamburg. In 1988 the company Hanns R. Neumann took over Bernhard Rothfos AG, which beginnings stem back to the year 1922. Neumann Kaffee Gruppe was created in 1990 by integrating the Neumann and Rothfos companies.

A Management Board under the leadership of Michael R. Neumann piloted the progress of Neumann Kaffee Gruppe to a well-organised global venture, which maintains a multi-local presence to serve its partners all over the world. The blending of traditional Hanseatic business principles with a global focus on producer country interest and customer dedication is central to the group's operations.  

Since the beginning of 2004, David M. Neumann has succeeded Michael R. Neumann as Speaker of the Board. Michael R. Neumann continues to actively contribute to Neumann Kaffee Gruppe's strategic development as Chairman of the Supervisory Board and in various consulting functions.
