Elisabeth S. Mortimer Garden Internship

The Elisabeth S. Mortimer Internship was created in 1994 when Elisabeth and Charles Mortimer made a generous donation to the Pinchot Institute for Conservation to set up an internship at Grey Towers National Historic Site. The focus is on gardening, one of Mrs. Mortimer's greatest passions. Because of the generosity of the Mortimers the chosen intern will receive a $2,500.00 stipend for the 12 week program.

Grey Towers is a French-style mansion designed by Richard Morris Hunt and built in 1886. The 101-acre site, administered by the USDA Forest Service, consists of formal, landscaped and wooded grounds.
