Muhlenberg College is a private liberal arts college located in Allentown, Pennsylvania, United States. Founded in 1848, Muhlenberg is affiliated with the Evangelical Lutheran Church in America and is named for Henry Melchior Muhlenberg, the patriarch of the Lutheran Church in America. Muhlenberg College was initially established in 1848 as the Allentown Seminary by Reverend Samuel K. Brobst, a Reformed Lutheran minister. Reverend Christian Rudolph Kessler was the school's first teacher and administrator. Between 1848 and 1867, the entity that is today Muhlenberg College operated as the Allentown Seminary, the Allentown Collegiate and Military Institute and the Allentown Collegiate Institute. In 1867, the college moved into Trout Hall, the former mansion of William Allen's son, James Allen, and was renamed after Henry Melchior Muhlenberg, the patriarch of the Lutheran Church in America. Muhlenberg's great-grandson, Reverend Frederick Augustus Muhlenberg, served as president of the college from 1867 to 1876. In 1905, the college purchased and relocated to a 51-acre (0.08 sq mi; 0.21 km) tract located in Allentown's West End, the site of today's campus.
