Passage: In July 2005 an authentic 1826 Beethoven manuscript titled "Grande Tugue [sic] à quatre mains" was found by a librarian at the Palmer Theological Seminary in Wynnewood, Pennsylvania. The manuscript was authenticated by Dr. Jeffrey Kallberg at the University of Pennsylvania and by Dr. Stephen Roe, head of Sotheby's Manuscript Department. This was the four-hand piano arrangement of the Große Fuge, Op. 134. The manuscript had been missing for 115 years. It was auctioned by Sotheby's Auction House on 1 December 2005; it was bought for GBP 1.12 million (USD 1.95 million) by a then-unknown purchaser, who has since revealed himself to be Bruce Kovner, a publicity-shy multi-billionaire who donated the manuscript—along with 139 other original and rare pieces of music—to the Juilliard School of Music in February 2006. It has since become available in their online manuscript collection. The manuscript's known provenance is that it was listed in an 1890 catalogue and sold at an auction in Berlin to a Cincinnati, Ohio industrialist, whose daughter gave it and other manuscripts including a Mozart Fantasia to a church in Philadelphia, Pennsylvania in 1952. It is not known how the Beethoven manuscript came to be in the possession of the library.
