Westminster Theological Seminary is a Presbyterian and Reformed Christian graduate educational institution located in Glenside, Pennsylvania, with a satellite location in London. The Seminary was formed in 1929, largely under the leadership and funding of J. Gresham Machen. Though independent, it has long had a close relationship with the Orthodox Presbyterian Church, which Machen helped found in 1936. The first president of the Seminary was Edmund Clowney, who served from 1966 until 1984. He was followed by George Fuller and Samuel T. Logan. In 1982, the California branch of Westminster became an independent institution, Westminster Seminary California, and in 2009 the Dallas, Texas branch was established as Redeemer Theological Seminary. The current president is Peter Lillback, who also serves as a professor of Historical Theology. Westminster was accredited in 1986 by the Association of Theological Schools in the United States and Canada and received accreditation in 1954 by the Middle States Association of Colleges and Schools.
