Question: David P. Billington is from what private institution, founded in 1746?

The Log College, founded in ca. 1726, was the first theological seminary serving Presbyterians in North America, and was located in what is now Warminster, Pennsylvania.  It was founded by William Tennent and operated from 1726 or 1727 until William Tennent's death in 1746, and it graduated proponents on the New Side of the significant Old Side-New Side Controversy that divided presbyterianism in colonial America at the time.  The Log College was, as a physical structure, very plain according to George Whitefield's journal; it was a purely a private institution and had no charter, though as a ministers' training college it was innovative, insofar as its founding was at a time when there were few college-educated ministers in North America.  In sources dated through the early 20th century, it was referred to as a remarkable institution, with graduates including Samuel Finley, John Redman, and John Rowland.  Though the number of eventual graduates is unknown (perhaps being 20 or less), many would play important roles in Old Side-New Side Controversy, and Log College alumni Samuel Blair, Samuel Finley, and William Tennent, Jr. would become trustees of a newly formed College of New Jersey, which would be renamed Princeton University in 1896. <SEP>  Founded in 1746 in Elizabeth as the College of New Jersey, Princeton is the fourth-oldest institution of higher education in the United States and one of the nine colonial colleges chartered before the American Revolution. Princeton University is a private Ivy League research university in Princeton, New Jersey, United States.  The institution moved to Newark in 1747, then to the current site nine years later, where it was renamed Princeton University in 1896. <SEP> Elk, also known as the David P. Thompson Fountain, David P. Thompson Monument, Elk Fountain, or the Thompson Elk, is an historic outdoor fountain and bronze sculpture by American artist Roland Hinton Perry.  The sculpture was donated to the city of Portland, Oregon, United States in 1900.  It is located in the Plaza Blocks in downtown Portland. <SEP> Certain works of structural engineering design are also works of structural art.  A key part of the concept of structural art is that the structural engineer making the design must exercise his or her creativity and playfulness to create an elegant structure within the constraints imposed by engineering requirements.  These constraints include the safety and serviceability of the structure.  Therefore, a structure cannot be a successful work of structural art without also being a successful work of structural engineering design, yet many works of structural engineering design that are safe and serviceable do not rise to the level of structural art because they fail to be economical, efficient, or elegant.  Such works can be classified as structural art when they attain excellence in the three areas of efficiency, economy, and elegance, as defined by Prof. David P. Billington of Princeton University.  Structural art is a topic of active scholarly research at several universities in the United States, including Princeton University, Tufts University, Bucknell University, University of Massachusetts Amherst, the Massachusetts Institute of Technology, and Roger Williams University, and in other parts of the world such as Spain (Universitat Politécnica de València) and Germany (HCU Hamburg).  While structural artists often collaborate with architects, the discipline of structural art is based upon engineering rather than architectural design.
