Belgian Violinist Arthur Grumiaux, 65; Performed With Pianist Clara Haskil

Arthur Grumiaux, a world-recognized violinist, has died in his native Belgium, a spokesman for his recording company, Philips Classics, announced this week.

Grumiaux, who had played publicly since he was 5, was 65 when he died Oct. 15 of an apparent heart attack, the spokesman said.

Probably best known for his association with pianist Clara Haskil, Grumiaux performed in a series of concerts with her throughout Europe and with her also made several records of Beethoven and Mozart sonatas in the 1950s that are considered among the best ever done.

He had established a promising concert career while in his teens but refused to perform during the German occupation of Belgium during World War II.

After the war, he made his debut over the British Broadcasting Co. and quickly became known outside his native land. With Georges Janzer on viola and Eva Czako on cello he recorded a series of Beethoven string works that continue to sell well.

In 1973, Grumiaux, who last appeared in the United States more than 20 years ago, was made a baron by King Baudouin of Belgium.
