Argonne National Laboratory is one of the United States Department of Energy's oldest and largest science and engineering research national laboratories and is the largest in size in the Midwest (approximately twice the area of the nearby Fermilab). The laboratory is managed by UChicago Argonne, LLC, which is composed of the University of Chicago and Jacobs Engineering Group Inc. It is located on 1,700 acres (6.9 km²) in DuPage County, 25 miles (40 km) southwest of Chicago, Illinois, on Interstate 55, completely encircled by Waterfall Glen Forest Preserve. When it was first established it was known as the University of Chicago's Metallurgical Laboratory (Met Lab), and it was previously located within Red Gate Woods. Early on the lab was part of the Manhattan Project, which built America's first atomic bomb.
