In the 1890s, this issue was brought forcefully to the attention of European Catholics by Comtesse de Ravilliax's translation of a biography of Isaac Thomas Hecker by Paulist father Walter Elliott, with the introduction by Abbé Felix Klein drawing the most ire from the Vatican. His biography, written in English by the Paulist Father Elliott in 1891, was translated into French six years later and proved an inspiration to the French. Father Hecker, commonly known as "The Yellow Dart," had been dead for years at this point and had never been viewed by the Pope with disfavor. However, this translation of Hecker's biography and Abbé Klein's introduction to the book made him appear to have been much more of a radical than he in fact was.
