From its opening in 1812, the Seminary has been blessed with able leadership, including its first professor, Archibald Alexander, and soon thereafter, Samuel Miller and Charles Hodge. It became the dominant influence in Presbyterianism in the United States for more than a century. Administered by its faculty with a rotation of leadership until 1902, its first president was Francis Landey Patton, previously president of the University, who was followed by J. Ross Stevenson in 1914, John A. Mackay in 1936, and James I. McCord in 1959.
Today, the Princeton Theological Seminary not only is the outstanding Presbyterian Seminary in the country but is one of the leading seminaries in the world. Its distinguished faculty of thirty-eight is supplemented by fourteen adjunct and visiting professors and more than fifty pastors and chaplains cooperating in field training. Its 740 students come from throughout the world and from many confessions. It awards advanced degrees and provides mid-career instruction to large numbers of ministers through institutes and special seminars. Its Speer Library is one of the best research libraries in its field. While remaining separate institutions, the Seminary and the University have cooperated in many ways in enriching the intellectual life of an academic community.
