VIENNA —U.S. writer Frederic Morton, who became internationally recognized in part through books on the Austrian homeland that he was forced to flee because of the Holocaust, has died, his Austrian publishers said Monday. He was 90.

The Deuticke publishing house said Morton died in his Vienna hotel room overnight on the eve of a public reading of some of his works in the Austrian capital. The Austria Press Agency said that event will now be turned into a memorial for the Vienna-born author. Morton wrote 12 books, including “The Rothschilds” and “A Nervous Splendor,” both of them National Book Award finalists. “The Rothschilds” was made into a Tony Award-winning musical, while “A Nervous Splendor,” chronicling 1888 to 1889 in Vienna, focused on the major Austrian personalities and events of that year – among them the birth of Adolph Hitler, whose rise to power led to Morton’s self-exile 40 years later. Decades later, Morton would describe his uprooting as the common theme running through all of his works, and not only those dealing with Austria.

“Everything I write has something to do with the loss of my homeland, directly or indirectly,” he told Austrian state broadcaster ORF.

Born Fritz Mandelbaum on Oct. 5, 1924, Morton grew up as the son of a well-to-do Jewish family of industrialists who fled first to London a year after Hitler’s 1938 annexation of Austria and then to New York.

Morton’s interest in writing grew while studying literature at Columbia University and attending classes at the New School for Social Research.
