Manuscript Collections

Buxtehude, Dietrich
Prelude and Fugue in G Minor

This treasure is a manuscript of three leaves in the hands of Johann Christoph and Johann Sebastian Bach. The manuscript contains the earliest known example of Johann Sebastian Bach's hand, as identified by Hans-Joachim Schultze of the Bach-Archiv. It is also one of the few extant pre-18th century manuscript sources of Buxtehude's organ works.

Craig Manuscript Collection
1768-1808

Forty bound volumes, approximately 5,000 manuscript items, and a small group of printed materials reflect the career of Major Isaac Craig. Located at Fort Pitt as quarter master general of the U.S. Army, his correspondence and letter books from 1791-1799 form an important part of this section.

The assemblage also contains smaller groups of papers belonging to several of his sons, especially Henry, John and Neville; papers on the Craig family and their various land holdings; and materials gathered and written by Isaac Craig's grandson and namesake, Isaac Craig.

Other valuable contributions include a journal by George Croghan, 1765; papers of Colonel George Morgan, Indian Agent, 1774-1778; and letters and papers on the Whiskey Insurrection, 1790-1800.
