Nathan Ancell; Co-Founded Furniture Firm

Nathan S. Ancell, 90, co-founder of Ethan Allen Inc., one of the nation’s largest furniture companies. Ancell entered the furniture business in 1932 as a young lawyer just out of Columbia University. He spent a vacation tending his brother-in-law Theodore Baumritter’s housewares company and never went back to law. The two men bought a factory in Vermont, where Ethan Allen, the leader of the Green Mountain Boys during the Revolutionary War, was a folk hero. To gain an edge in the market, Ancell decided that instead of selling piecemeal, he would sell furniture systems and signed up retailers who would offer the entire Ethan Allen line of colonial furnishings, from bedroom set to dining room table. He later opened more than 300 Ethan Allen stores, all housed in identical Georgian-style buildings. A pioneer in the industry, he sold whole rooms of furniture and flourishes, including drapes, wallpaper, even knockoffs of Picassos, Monets and Van Goghs, which he called Artagraphs, to go along with the rest of his merchandise. “We are selling what you can do with the product, not the product itself,” he told Forbes magazine in 1978. “We offer the middle class a service that only the rich could afford.” His company was sold for $150 million in 1980 to Interco Inc. of St. Louis. In his retirement years, Ancell turned a personal hobby into another, much smaller business: a store in White Plains, N.Y., called World of Interior Design. Created for his daughters, it was opened to sell off 6,000 objets d’art he had collected over 60 years. On Monday at his home in New Rochelle, N.Y.

Robert Sobel; Author, Business Historian

Robert Sobel, 68, prolific business historian and newspaper columnist who wrote or edited more than 50 books. A professor at New York’s Hofstra University, where he spent 40 years, Sobel specialized in the history of business, aiming his works at a mass market. His topics ranged from the financial markets, as in his 1968 “Panic on Wall Street: A History of America’s Financial Disasters,” to IBM and the economic philosophy of Calvin Coolidge. Sobel relied on vignettes, anecdotes and reminiscences to compile his studies, which some critics found unoriginal and others called brisk and entertaining. The National Review, for instance, said his “Coolidge: An American Enigma,” published in 1998, offered “no new revelations” but still was informative and highly readable. His main talent, wrote Gerald Carson in the New York Times review of “Panic on Wall Street,” was enlivening matters “that might otherwise remain somewhat abstract.” On Wednesday of brain cancer at his home in Long Beach, N.Y.
