attempted to create an "American Riviera". With the success of the Ponce de Leon, Flagler realized the need for a sound transportation system to support his resorts, and he purchased short-line railroads to form what would later become known as the Florida East Coast Railway. He modernized the existing railroads for them to accommodate heavier loads and more traffic, allowing guests to reach the hotel from New York City and other northern cities. Over the next two decades, Flagler expanded the system further south, until it reached Key West. Noted personalities that stayed at the hotel during its operation included President Grover Cleveland, Mark Twain, President Theodore Roosevelt, Somerset Maugham, Babe Ruth and Babe Didrikson. The headwaiter of the Ponce in the 1880s and 1890s was Frank Thompson, who was a pioneer civil rights advocate and an organizer of the professional black baseball team that became the Cuban Giants. One member of the team, Frank Grant, was elected to the Baseball Hall of Fame. The hotel saw declining visitor numbers throughout the 1910s and 1920s. A major cause of this was the continuous extension of Flagler's railway, which allowed tourists to vacation in the warmer, tropical climates further south, giving rise to cities like West Palm Beach and Miami. However, even as the Alcazar and Cordova Hotels closed, the Ponce remained open and was one of three Flagler hotels in the state to survive the Great Depression and operate into the mid-20th Century. Art colony Flagler established an artist colony at the hotel, with an Artists' Studios building constructed to the rear of the resort. The colony attracted many up-and-coming American artists of the time, including Martin Johnson Heade, who painted, among other works, "Giant Magnolias on a Blue Cloth" in Studio No. 7. The painting now hangs in the National Gallery of Art in Washington, D.C., and Heade has been honored on a U.S. postage stamp. Other works of his are in the White House and various significant galleries. Other artists of the colony included Felix de Crano, Reynolds Beal, Arthur Vidal Diehl, the flower painter Albert Fuller Graves, the Provincetown artist and teacher Charles Webster Hawthorne, the impressionist painter Harry L. Hoffman, and Heinrich Pfeiffer. During the Great Depression, the federal government had organized several of its direct aid programs in the city with the goal of revitalizing the area's tourism economy.
