Pierre S. du Pont graduated from MIT with a degree in chemistry and took courses in mechanical drawing, water analysis, and physics, among others. He was introduced to new technologies during visits to World's Fairs at the turn of the 20th century. Mr. du Pont was inspired to use these developments to enhance beautiful spaces at Longwood. He and his electrical engineer Russell Brewer methodically experimented with the latest pumps, nozzles, and lights, often working with the manufacturers to create something new. Mr. du Pont personally annotated 56 pages of calculations and test results to create Longwood's biggest and most spectacular hydraulic display, the Main Fountain Garden.

Beyer Blinder Belle, Initial Report for Main Fountain Garden. "The Main Fountain Garden is often refered to as an Engineer's Garden, due to its technical complexity."
