William Lightfoot Price (November 9, 1861 – October 14, 1916) was an American architect, a pioneer in the use of reinforced concrete, and a founder of the utopian communities of Arden, Delaware and Rose Valley, Pennsylvania.

James had previously taught at the Quaker Westtown School and later became an insurance salesman for the Provident Life and Trust Company.

The owners of Philadelphia's Strawbridge & Clothier Department Store were investors with George W. Vanderbilt in a proposed resort hotel in Ashville, North Carolina, and may have recommended Price to design the Kenilworth Inn (1890–91, burned 1909).

Price experimented with new materials, especially reinforced concrete, that were cheaper for constructing hotels and industrial buildings, and allowed wide spans and soaring spaces.

At Rose Valley, a utopian community he co-founded, he built new buildings and altered existing ones, creating an Arts & Crafts village.

Following the 1976 legalization of gambling in the city, architect Robert Venturi hoped to make the building the centerpiece of a casino-hotel, but its reinforced concrete had deteriorated so much that it could not be saved.

The Single-Taxers hoped that by gaining control of a small political entity they could put their principles into action and show that they could really work.

Stephens and Price adopted "You are welcome hither" as the community motto because they wanted Arden to be a place open to people of all economic levels and political views, a new departure in an era when restrictions were the norm.

Price never lived in Arden, but built and owned a handful of cottages;—he was more deeply involved in Rose Valley, another idealistic community nearby in Pennsylvania—but Frank Stephens did.

The houses he built before founding Rose Valley are made from the same hodge-podge of materials as any other turn-of-the-century American architect used for the show places of rich clients: cut and rough stone, cedar and slate shingles, Gothic and half-timber wood work, red brick and buff stucco.

He admonished both rich and poor to “...dispense with the plush albums and tea-store chromos and self-playing melodeons and comic operas and the daily installment of wood-pulp which calls itself the modern newspaper.

Citing the way the house fit its site, the way the pergola helped integrate the building and gardens, the use of local materials, and the references to indigenous architecture, magazines compared it to the designs of Frank Lloyd Wright who was then just beginning to develop his signature Prairie School style.

He was instrumental in the founding of the American Civil Liberties Union, and she was a tireless proponent of the Women's International League for Peace and Freedom.

Under the terms of Mildred Scott Olmsted's will, Thunderbird Lodge was donated to the Rose Valley Centennial Foundation in 2015 "to preserve it in perpetuity".
