The Pullman factories soon themselves became the focus of attention by salesmen from all over the world. Suppliers of iron, steel, upholstery, and many other commodities needed for the manufacture of sleeping cars descended upon Pullman. The industrial magnate approved the design, by architect Solon Spencer Beman, and the construction of the new 50-room Hotel Florence to rent rooms to these supply representatives. The hotel cost $100,000 (in gold-standard dollars) to build. George Pullman named the hotel after his oldest daughter, Florence Pullman. The most luxurious suite in the hotel, the Pullman Suite, was designed for the personal use of George Pullman and his family. The hotel could also offer first-class accommodations to railroad CEOs who came to Pullman to do business with the firm. The hotel opened to guests on November 1, 1881.
