We return from vacation with sad news: the conductor Yakov Kreizberg died today at home in Monte Carlo, age 51, in the presence of his wife and two sons, after a long illness, according to his manager, Linda Marks of Harrison Parrott.

Kreizberg was Chief Conductor and Artistic Advisor of the Netherlands Philharmonic and Netherlands Chamber Orchestra, and principal guest conductor of the Vienna Symphony Orchestra (not to be confused with the Vienna Philharmonic). Past posts included that of principal conductor of the Bournemouth (U.K.) Symphony Orchestra and that of general music director at Berlin’s Komische Oper.

He last conducted the National Symphony Orchestra at the Kennedy Center in 2008; he had also conducted the Baltimore Symphony Orchestra, and performed at George Mason University with the Bournemouth orchestra in 1997.

Kreizberg was a member of a musical family; his brother is the conductor Semyon Bychkov.

In an introductory series of videos posted two years ago, the violinist Hilary Hahn interviewed Kreizberg and Florian Zwiauer, the concertmaster of the Vienna Symphony, about their roles.
