Ellen Krieger, v-p and associate publisher of Aladdin, will retire at the end of June. She joined Simon & Schuster in 1994 as Aladdin’s v-p, editorial director, after serving as editorial director of the Flare and Camelot imprints at Avon Books for 10 years. She had previously been subsidiary rights manager for Harper Junior Books. While at Aladdin, she oversaw the merging of Pocket Books’ middle grade and teen imprints into the children’s division, and launched Aladdin M!X, the first branded program targeting tweens. Under her watch Aladdin has grown from an in-house paperback imprint to a full hardcover/softcover imprint.
