Book excerpt: Kaufmann's Department Store was a force in Pittsburgh retail from its humble beginnings in 1871 until its merger with Federated Department Stores in 2006. The "Big Store" downtown was a landmark shopping emporium with 12 floors of everything from cosmetics and groceries to wedding gowns and lawn mowers. Under the leadership of Edgar J. Kaufmann and his wife, Liliane, the store became a forum for exhibitions of art, cutting-edge technology, and Parisian haute couture. Generations of Pittsburghers hold fond memories of meeting friends and family under the famous Kaufmann's clock to lunch at the Tic Toc Restaurant, pick up cookies at the Arcade Bakery, or peer into the store's enchanting Christmas window displays each December.
