In America, Candace Wheeler was one of the first woman interior designers and helped encourage a new style of American design. She was instrumental in the development of art courses for women in a number of major American cities and was considered a national authority on home design. An important influence on the new profession was The Decoration of Houses, a manual of interior design written by Edith Wharton with architect Ogden Codman in 1897 in America. In the book, the authors denounced Victorian-style interior decoration and interior design, especially those rooms that were decorated with heavy window curtains, Victorian bric-a-brac, and overstuffed furniture. They argued that such rooms emphasized upholstery at the expense of proper space planning and architectural design and were, therefore, uncomfortable and rarely used. The book is considered a seminal work, and its success led to the emergence of professional decorators working in the manner advocated by its authors, most notably Elsie de Wolfe.
