NEW YORK — Harold Shaw, an artist manager whose clients included some of the most famous performers in classical music, died Tuesday at his home in New York. He was 90.
The cause was pancreatic cancer, said his son, José R. Cifuentes.
During his career Shaw’s starry roster included guitarists Julian Bream and John Williams, violinist Nathan Milstein, cellist Jacqueline du Pré and singers Jessye Norman and Janet Baker. A friend of pianist Vladimir Horowitz and his wife, Wanda, Shaw helped persuade Horowitz, who suffered from depression and stage fright, to return to regular performances in 1974 after a long absence.
Shaw, who began his career working with the celebrated impresario Sol Hurok, founded his own agency, Shaw Concerts, in 1969. Full story for BostonGlobe.com subscribers.
