Our 100 Year History

Initially known as 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. Following his liberation from a concentration camp in 1945, Mr. Magnus started from scratch to rebuild his business, and the firm grew rapidly.

As MMI continued to expand, the firm was reestablished as Metaal Magnus International — keeping the name of our founder and role model, Mr. Magnus, in place. In 2017, MMI transferred its company headquarters to Amstelveen, on the outskirts of Amsterdam, while retaining warehousing near the Port of Antwerp for easy access to one of the largest European ports.

Today, MMI has grown to include operations across 3 continents, including the USA and UK — the latter headed by a fourth-generation Magnus family member.

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
