Sylvia Rosen Baumgarten ’55, of La Jolla, Calif., formerly of New York City; Feb. 1, of lung cancer. She was an author, a raconteuse, “queen bee” of the bridal salon, and “Maw,” says her son. She had a million expressions for every occasion and died wearing her favorite sweatshirt, which read, “I’m not bossy. I just know what you should be doing.” From 1982 to 2015 under the pen names Ena Halliday, Louisa Rawlings, and Sylvia Halliday, she wrote for a variety of publishers, including Pocket Books, Harlequin, Kensington Publishing, and Diversion Books. She authored 15 historical romance novels that were highly praised and translated into multiple languages. In addition, she received several awards for her writing, including 1986 and 1987 Gold Medallion Finalist awards from the Romance Writers of America (RWA), a 1989 Reviewer’s Choice Award from Romantic Times magazine, and she was a 1994 RWA RITA Award Finalist. Later on, continuing in the romance sector, she took a job as a wedding gown saleswoman in New York City. She was president of the Romance Writers of America New York City chapter. She played the piano and was a fan of theater, opera, ballet, and classical music. She also enjoyed words and word play and had a Sunday crossword published in the New York Times on July 4, 1971. She had an encyclopedic knowledge of trivia and was a contestant on the game shows Jeopardy! and Who, What, or Where Game. In her 80s, she started a blog titled “Life Lessons from an Old Bitch,” which consisted of a mix of reminiscences, nostalgia, commentary on society, and advice for younger generations. She moved to Atria La Jolla senior independent living in San Diego in 2020 to be close to her daughter and, while there, wrote for and edited the Atria newsletter and participated in play readings. She signed her letters and emails to her children as Maw. She is survived by four children, including sons Fredrick Baumgarten ’79 and Roger Baumgarten ’82; daughter-in-law Barrett Sheridan ’82; sister Deena Rosen Mazer ’62; brothers-in-law Joel Baumgarten ’59 and Samuel Baumgarten ’65; niece Deborah Baumgarten ’85, and former husband Sidney Baumgarten ’54.
