Josef Suk, a Czech violinist who was known for his warm-toned interpretations of works by Mozart, Beethoven, Debussy and Janacek as well as for his lineage — he was a great-grandson of Dvorak and a grandson of the turn-of-the-century violinist and composer also named Josef Suk — died on Wednesday in Prague. He was 81 and a lifelong Prague resident. The cause was prostate cancer, said Antonin Matzner, a program adviser at the Prague Spring International Music Festival, of which Mr. Suk was honorary president.

Tall, elegant and silver-haired, Mr. Suk pronounced souk, at the height of his career, projected a thoughtfulness and an authority in his music-making that more than compensated for his disinclination to wrap his performances in technical flashiness. New York Times
