PRAGUE (AP) – A musical manuscript handwritten by Ludwig van Beethoven is being returned to the heirs of the richest family in pre-World War II Czechoslovakia, whose members had to flee the country to escape the Holocaust. The Moravian Museum in the Czech city of Brno has had the original manuscript for the fourth movement of Beethoven’s String Quartet in B-flat Major, Op. 130 in its collection for more than 80 years. The museum put the score on display for the first time in early December in anticipation of handing it over to its rightful owners.
