Museum Overview 
Hagley is where the du Pont story begins in the Brandywine Valley and features the original du Pont mills, estate, and gardens. Hagley extends over 235 acres along the Brandywine River. Exhibits and demonstrations bring this important chapter in American history to life. Hagley tells the story of the people who worked for the DuPont Company in the nineteenth century, how they lived, and how their lifestyles changed during a century in tune with new machinery and new production methods in their workplace.
The Hagley Museum exhibits history from the early years of the du Pont family and corporation in the Brandywine Valley. It features the original du Pont mills, estate and gardens. The museum opened in 1957. The Hagley Museum and Library extends over 235 acres (0.95 km²) along the banks of the Brandywine Creek. Exhibits and demonstrations showcase the connections between early industrial technology and early American history. The Hagley Museum also exhibits personal stories of the people who worked for the DuPont Company in the nineteenth century, how they lived, and how their lifestyles changed during a century in tune with new machinery and new production methods in their workplace.
In 1802 a French immigrant, Eleuthere Irenee du Pont, chose the banks of Brandywine Creek to start his black powder mills. He chose the location because of the natural energy that the water provided; the availability of timber and willow trees (used to produce quality charcoal required for superior black powder); the proximity to the Delaware River (on which other ingredients of the powder – sulfur and saltpeter – could be shipped); and the quarries of gneiss which would provide building materials for the mills. The E. I. du Pont de Nemours & Company's black powder manufactory became the largest in the world. In 1921 the mills along the Brandywine closed and parcels of the property were sold. It was on the occasion of the DuPont Company's 150th anniversary in 1952,that plans for a museum were established. Of course this is the site that began the DuPont legacy and it is located at the midpoint of the DuPont Historic Corridor.
Origin of the name 
Hagley historians only know that the name was already in use well before E.I. du Pont expanded downstream from Eleutherian Mills in 1813 by purchasing the land that became the Hagley Yards. An 1813 document refers to the land as Hagley and it had been called Hagley as early as 1797, when its owner, Philadelphia Quaker merchant Rumford Dawes, applied for insurance on buildings that were said to be located in a place called Hagley on the Brandywine. Dawes had acquired the property in 1783. Since the name Hagley did not appear on the documents transferring ownership at that time, it seems likely that Dawes gave this name to the Brandywine location.
It seems likely that Delaware's Hagley was named for an English estate that was well known in the second half of the eighteenth century. It is likely that Dawes chose the name based on an English narrative poem by James Thomson. Hagley Hall was the seat of Thomson's patron the Baron Lyttleton, and the poem's description of a sylvan dale is strikingly reminiscent of the Brandywine Valley. The Seasons was popular in Philadelphia at the time that Rumford Dawes acquired and named Hagley. No other place of that name is known to have existed in eighteenth- century Europe or America. The English Hagley estate is located in the West Midlands countryside approximately ten miles southwest of Birmingham.

The museum and grounds include the first du Pont family home and garden in the United States, the powder yards, and a nineteenth-century machine shop. On the hillside below the mansion lies a Renaissance-Revival garden, with terraces and statuary, created by Louise Evalina du Pont Crowninshield (1877–1958) in the 1920s.
