To the Editor:

Your obituary on the British writer Roald Dahl (Nov. 24) omits an important aspect of the subject's life. Mr. Dahl, well known for his children's books, as well as writings dealing with the dark, bizarre side of human nature, such as "Tales of the Unexpected," had his own dark and unexpected side: he was a blatant and admitted anti-Semite.

In 1983, the British periodical Literary Review published a book review by Mr. Dahl in which he referred to "those powerful American Jewish bankers" and charged that the United States Government was "utterly dominated by the great Jewish financial institutions over there."

Later that same year, defending these outrageous statements, Mr. Dahl stated in an interview that was published in the British magazine New Statesman:

"There is a trait in the Jewish character that does provoke animosity, maybe it's a kind of lack of generosity towards non-Jews. I mean there is always a reason why anti-anything crops up anywhere; even a stinker like Hitler didn't just pick on them for no reason."

The British poet Stephen Spender and the historian Paul Johnson protested Mr. Dahl's anti-Semitic outburst, while in this country The New Republic (Oct. 31, 1983) referred to his Literary Review comments as the "ugliest piece of anti-Semitism to appear in a respectable setting for a long time." But Mr. Dahl was not finished.
