Arnold Hague (December 13, 1840 - May 14, 1917) was an American geologist and surveyor active in the late 18th and early 19th century. Hague was born in Boston, Massachusetts in 1840. As the son of a clergyman he was well educated and graduated from Yale University in 1863. Afterwards he traveled for Europe where he pursued further studies in geology at Gottingen, Heidelberg, and Freiberg. Upon his return to the United State in 1867 Hague was assigned to assist Clarence King in a study of the surface geology of the Comstock Lode and the amalgamation process, known as the ‘Washoe Process' practiced there. When the U.S. Geological Survey was formed in 1879 Hague became a founding member. In 1883 he was commissioned as the official geologist of Yellowstone National Park and assigned to study the parks famous geysers. Hague's report on Yellowstone, published in 1904, is perhaps his most significant work and certainly the work for which is best known today. Hague died in Washington D.C. in 1917. He was a member of the National Academy of Sciences, vice president of the International Congress of Geologists, and president of the United States Geological Society. Learn More...

Julius (Julien) Bien (September 27, 1826 - December 21, 1909) was a German-Jewish lithographer and engraver based in New York City. Bien was born in Naumburg, Germany. He was educated at the Academy of Fine Arts, Cassell and at Städel's Institute, Frankfurt-am-Main. Following the suppression of the anti-autocratic German Revolutions of 1848, Bien, who participated in the pan-German movement, found himself out of favor in his home country and joined the mass German immigration to the United States. Bien can be found in New York as early as 1849. He established the New York Lithographing, Engraving & Printing Company in New York that focused on the emergent chromo-lithograph process - a method of printing color using lithographic plates. His work drew the attention of the U.S. Government Printing Office which contracted him to produce countless government maps and surveys, including the Pacific Railroad Surveys, the census, numerous coast surveys, and various maps relating to the American Civil War. Bien also issued several atlases both privately and in conjunction with a relation, Joseph Bien. At the height of his career Bien was elected president of the American Lithographers Association. After his death in 1909, Bien's firm was taken over by his son who promptly ran it into insolvency. The firm was sold to Sheldon Franklin, who, as part of the deal, retained the right to publish under the Julius Bien imprint. In addition to his work as a printer, Bien was active in the New York German Jewish community. He was director of the New York Hebrew Technical Institute, the New York Hebrew Orphan Asylum, and president of the B'nai B'rith Order. Learn More...
