The Grede legacy dates to 1920 when William J. Grede founded Grede Foundries, Inc., with an iron foundry in Wauwatosa, Wis.  The company has grown through a series of acquisitions. In February 2010, Grede combined assets with Citation Corporation to create the most diversified foundry company in North America.  In August 2014, Metaldyne Performance Group (MPG) was formed by the joining of Metaldyne, HHI and Grede, and in 2017, MPG was purchased by American Axle & Manufacturing Holdings, Inc.
