William Appleton Potter (December 10, 1842 – February 19, 1909) was an American architect who designed numerous buildings for Princeton University, as well as municipal offices and churches.
For Princeton, retaining Potter represented a shift from dependence on Philadelphia architects to a New York practitioner.
Under his supervision, designs were produced for customhouses, courthouses, and post offices in Kentucky, Indiana, Massachusetts, Georgia, and Tennessee.
From 1875 to 1881, along with major public projects, the firm produced summer vacation cottages in Newport, Rhode Island, and the Jersey Shore, as well as the Adam-Derby House at Oyster Bay, New York.
In addition, the Innis Arden Cottage, which was designed by an associate of Potter, Katherine C. Budd, an early and prominent woman and architect, remains on the property as well.
