Biographical note: Eugene S. Ives, Tucson, Arizona attorney and politician, was born in Washington, D.C. in 1859. He moved to Arizona around 1895, first to Yuma, and then to Tucson in 1901. Soon after his arrival in Arizona he obtained a position as counsel for the Southern Pacific Railroad. In 1900, he was elected to the territorial legislature and he was an active member of the Arizona state Democratic Party. Ives enjoyed a successful law career, representing such Arizona legends as W.P. Hunt and William Greene. He is also known for his representation of Mexican citizens in 1911 in the Chamizal Land Company lawsuit in El Paso, Texas. Eugene Semmes Ives was the third son of Joseph Christmas and Cora Semmes Ives. Born in New York City on December 25, 1828, Joseph graduated from West Point in 1852. As an engineer in the U.S. Army, he worked with A.W. Whipple on the Pacific Railroad survey along the 35th parallel in 1853 and 1854. In 1859, Joseph commanded the Colorado River Exploring Expedition to determine the head of navigation of the river, and to explore the river farther upstream by land. He was one of the first Anglos to set foot in the Grand Canyon.
