Sphinx and Andromeda. All nudes, these works provoked great controversy and were ultimately hidden behind a drape with special permission given for viewers to see them.Bust of Dalou and Burgher of Calais were on display in the official French pavilion at the fair and so between the works that were on display and those that were not, he was noticed. However, the works he gave Hallowell to sell found no takers, but she soon brought the controversial Quaker-born financier Charles Yerkes (1837–1905) into the fold and he purchased two large marbles for his Chicago manse; Yerkes was likely the first American to own a Rodin sculpture. Other collectors soon followed including the tastemaking Potter Palmers of Chicago and Isabella Stewart Gardner (1840–1924) of Boston, all arranged by Sarah Hallowell. In appreciation for her efforts at unlocking the American market, Rodin eventually presented Hallowell with a bronze, a marble and a terra cotta. When Hallowell moved to Paris in 1893, she and Rodin continued their warm friendship and correspondence, which lasted to the end of the sculptor's life. After Hallowell's death, her niece, the painter Harriet Hallowell, inherited the Rodins and after her death, the American heirs could not manage to match their value in order to export them, so they became the property of the French state. Great Britain After the start of the 20th century, Rodin was a regular visitor to Great Britain, where he developed a loyal following by the beginning of the First World War. He first visited England in 1881, where his friend, the artist Alphonse Legros, had introduced him to the poet William Ernest Henley. With his personal connections and enthusiasm for Rodin's art, Henley was most responsible for Rodin's reception in Britain. (Rodin later returned the favor by sculpting a bust of Henley that was used as the frontispiece to Henley's collected works and, after his death, on his monument in London.) Through Henley, Rodin met Robert Louis Stevenson and Robert Browning, in whom he found further support. Encouraged by the enthusiasm of British artists, students, and high society for his art, Rodin donated a significant selection of his works to the nation in 1914. After the revitalization of the Société Nationale des Beaux-Arts in 1890, Rodin served as the body's vice-president. In 1903, Rodin was elected president of the International Society of Painters, Sculptors, and Engravers. He replaced its former president, James Abbott
