German composer Hans Werner Henze, whose prolific and wide-ranging work included a wealth of operas and 10 symphonies, died Saturday, his publisher said. He was 86.

The Semperoper opera house in Dresden recently kicked off a tribute to Henze with a performance of his antiwar drama “We come to the River,” produced in collaboration with writer Edward Bond and first performed in London in 1976.

Alongside his operas, Henze was known for his symphonies, among them “Sinfonia N. 9,” finished in 1997 a choral symphony based on Anna Seghers’ novel “The Seventh Cross” that reflected his anti-fascist convictions.

As well as composing, Henze took teaching assignments in Austria, the U.S., Cuba and Germany. He served as composer-in-residence at the Berkshire Music Center in Tanglewood, Massachusetts, and at the Berlin Philharmonic, Schott Music said.
