Sometimes referred to as Hercules, Inc., the Hercules Powder Company (“Hercules”) was created as a result of a DuPont antitrust lawsuit in the early 1900s.  Based in Wilmington, Delaware, Hercules soon opened the Bacchus Works facility in Magna, Utah.   Initially a small dynamite manufacturing firm, Hercules evolved into a munitions manufacturer for the U.S. military and a rocket producer for NASA.  Employing as many 4,500 workers, the Bacchus Works facility was a significant employer to residences of Bacchus, Magna, and West Valley.  

Hercules’ presence in Utah ended in the late 1990s when its two divisions were sold.  Alliant TechSystems (ATK) purchased the Hercules Aerospace Division of Bacchus Works in 1995.  The Hercules’ Composite Product Division was purchased by Hexcel Corporation in 1996.
