Margaret Russell, the editor-in-chief and vice president for brand content at Elle Decor, has been named editor-in-chief of Condé Nast’s Architectural Digest. She will succeed Paige Rense who has edited Digest for nearly 40 years.

Russell has made Elle Decor a credible rival for Digest, and is respected for her taste and discerning eye. Digest remained virtually unchanged for much of Rense’s long tenure there, so many expect Russell will update the magazine’s image as well as bring new architects and designers into its pages.

The magazine’s offices will relocate from Los Angeles to New York. Russell will take over in September.
