Our 100 Year History

Metaalhandel J.A. Magnus B.V.
Founding 1920-1975
From a casual glance at the "Who's Who" in the Netherlands one can quickly recognize the rapid growth of the MMI group. Initially known by the name Metaalhandel J.A. Magnus B.V. The firm was founded in Hamburg, Germany in 1920 by the late J.A. Magnus. Mr. Magnus escaped from Germany in 1937 and settled in Amsterdam. During the bombing of Rotterdam in 1940 his entire yard and stocks were destroyed. Following his liberation from a concentration camp in 1945, Mr. Magnus started from scratch to rebuild his business. The firm grew rapidly and moved to Metropool Building at Weesperstraat 73. (Adapted From Recycling Today - July 1974)
Metal Magnus Int. B.V. - 1974
Metal Magnus Int. B.V. - 2017

As MMI continued to expand and it's workload growing across the world, the firm was reestablished as Metaal Magnus International, keeping the name of our founder and role model, Mr. Magnus in place.

2017 and beyond
In 2017 the appeal of our waterfront location brought developers to the area and MMI made the choice to transfer our company headquarters to the city of Amstelveen located just on the outskirts of Amsterdam. While retaining our warehousing and works near the Port of Antwerp for quick and easy access to one of the largest European ports, MMI's offices remain centrally located in the heart of the European business district for easy access to our clients throughout the region.

MMI has grown to include operations across 3 continents including the USA and UK, the latter of which is headed by a fourth generation Magnus family member who had this to say about the modern day MMI.

"We are proud to continue operating based on the traditions my great grandfather worked hard to build our reputation on. Honesty and safety are our only concerns. My Grandfather was worried about the environment long before it was politically correct to do so" .

Z. Meisner (great grandson of MMI founder Mr. J.A. Magnus)
