began in 1887 as "Compton," the summer home of John and Lydia Morris, brother and sister. The I.P. Morris Company, an iron-manufacturing firm founded by their father and later run by John Morris, was a source of family wealth.

The land the Morrises purchased in Chestnut Hill was barren, with poor soil that drained too quickly; but with diligent care they surrounded their home with a landscape and plant collection devoted to beauty and knowledge. "Two Lines," a sculpture by George Rickey marks the former mansion site. The Widener Visitor Center was formerly the carriage house.
John was a noted plantsman and community leader who explored the new world of knowledge available to Victorians. John and Lydia traveled widely in America, Asia, and Europe bringing ideas, artwork, crafts and plants back to Compton. They shared a love of history and art, and established a tradition of placing sculpture in the garden that continues today. The Morrises were active in civic affairs and preservation, and believed in the power of education. It was their earnest hope to be judged "worthy stewards."John and Lydia Morris laid plans for a school and laboratory at Compton devoted to horticulture and botany. Through the stewardship and vision of the Quaker family, Compton became the Morris Arboretum of the University of Pennsylvania in 1932. Listed on The National Register of Historic Places, it is an interdisciplinary resource center for the University, and is recognized as the official arboretum of the Commonwealth of Pennsylvania. Science, art, and humanities are pursued through a variety of research, teaching, and outreach programs that link the Arboretum to a worldwide effort to nurture the earth's forests, fields and landscapes.
