Harriet Pattison, the landscape architect behind notable Pennsylvania structures, including Hershey’s corporate campus, has passed away at 94 years old, writes Fred A. Bernstein for The New York Times.  

The Newtown Square resident has often been tied to the noteworthy architect Louis Khan with whom she collaborated on projects, and also shared a son. However, her brilliant designs and 30 years of experience speak for themselves.  

In addition to the 150-acre campus, Pattison is the brains behind North Philadelphia’s Columbia Avenue Station. Other projects include landscapes for private homes across the Keystone State and Maine.  

In 2016 she presented her work at her alma mater, the University of Pennsylvania. Thanks to her artistic prowess, the American Society of Landscape Architects named her a fellow the same year.

Her projects with Khan include the Kimbell Art Museum in Fort Worth, Texas, and the Franklin D. Roosevelt Memorial on New York City’s Roosevelt Island.  

Pattison is solely survived by her filmmaker son Nathaniel Khan. Despite never marrying his father, she persevered in establishing herself as a single mother. 

While Pattison faced hurdles due to her lifestyle and marital status, she continued to blossom as an architect and master her craft.
