Joseph Franz Weigl
Joseph Franz Weigl was a Bavarian and Austrian cellist. He was the principal cellist in the orchestra of the Esterházy family, before moving to Vienna and the Burgtheater. He played under the directorship of Joseph Haydn, who also was godfather to the cellist's son, and it is thought that Haydn wrote his cello concerto in C major for him.
He was the father of Joseph Weigl, the composer and conductor, and Thaddäus Weigl, the composer and music publisher.
