Sylvia Welter was the spouse of J. D. Salinger.

"Salinger allegedly annulled this marriage, because he learned that she was a Gestapo informant. The evidence the book provides in this regard is speculative, noting that the annulment decree accuses Welter of “false representation.” It also quotes Leila Hadley Luce, a journalist and former girlfriend of Salinger’s, who says: “He said he found out some disturbing things about what she did in the war, specifically with the Gestapo. . . . Jerry said she had lied to him and that when he learned what she had really done in the war he could not possibly remain with her.” "
