1901: Aage Gerstenberg and Christian Agger establish G&A as a consulting engineering company.

Our history
Gerstenberg & Agger A/S was founded in 1901 by engineers Aage Gerstenberg and Christian Agger.
Since 1916, the Gerstenberg family was the sole owner of the
company, which in the first few decades primarily earned its money
as consulting engineers. In the subsequent decades Gerstenberg
& Agger A/S specialized in the development, production and
installation of equipment for the food industry, and at the end of
the century the company was the leading manufacturer of food
processing plants in the world.
In 2004 Gerstenberg & Agger A/S acquired Schröder GmbH. The
year after the two companies merged all main activities and
transferred them to the new subsidiary Gerstenberg Schröder A/S.
This company was sold to SPX Flow Technology in 2010.
