The "her" of course, was Saltaire's ANDY LOGAN, a/k/a MRS LYON, mom of Jon and his siblings of Broadway and Harbor Prom.
Andy Logan came to New York from Ohio or somewhere after Swarthmore, adopted the name of her hero, New Yorker writer E.B. White, and, in what had to be a dream job, got a job writing for that magazine for the rest of her life. Koch's dream of running her down was never realized, but that remark shows the kind of great journalist Andy Logan was. Her papers are archived in the New York Public Library "Andy Logan" collection.
Andy sometimes wrote the Saltaire column for the Fire Island News. Below is a piece she wrote for the Fire Island Guide in 1966. More on Andy's Curriculum Vitae follows the article.
