The positiv pipe organ formerly located in Blaisdell Hall at the University of Pittsburgh, Bradford could be rolled onto the stage for concerts. Otherwise it was located in the rehearsal/lecture hall (shown below left). The instrument was originally built by M.P. Moeller of Hagerstown MD for Temple Beth Zion in Bradford, PA in 1936 to accompany a small chior. It was rebuilt in 1948 after a flood accident. In 1963 it was moved to Temple Beth El, a larger space, and the swell box was dismantled to make it louder and clearer. In the following decades, the use of choirs and organs in Reform Jewish liturgy declined due to a conservative movement. The choir was disbanded in the 1980s and the instrument was very rarely used.

In 1996-1997 it was revoiced by L. R. Lawson for chamber music use. A celebratory chamber concert, titled CHESVAN 19, after its Hebrew date, was performed by the Southern Tier Consort under the direction of Richard Snyder with players including flautist, Peter Hurd and keyboardist, Laura Peterson (The Bradford Era 11.7.1998). The concert featured John Loeillet's (b. 1675) Trio Sonata and other works of that period for positiv organ with other instruments. In 2006 the organ was donated to the University of Pittsburgh. The case was reconfigured exposing the pipework to intensify its brilliance suiting it for the large Bromeley Theater. Large casters were then installed to make it a moveable positiv. It remained there until the retirement of the university's music director, Lee Spear in 2009.

POSTSCRIPT: After Professor Spear's, retirement the organ was placed in storage. In September 2010 the University issued a memorandum that it was disposing of the organ. In Summer 2011 the Division of Communications announced that it was considering using the instrument for teaching purposes and in October 2011 it was returned to the rehearsal/lecture hall.
