Pedro de Altube Idigoras (April 27, 1827 – August 8, 1905) was a Basque-born American rancher who established, along with his brother Bernardo, the renowned Spanish Ranch in northwestern Nevada. Pedro Altube and his brother Bernardo had emigrated from Spain to Argentina and from there, in 1849, he joined the rush for gold in California, amassing a small fortune not only in the mining camps but in very lucrative cattle and dairy operations. The Altube brothers then established a ranch in northeastern Nevada — the extensive and prosperous Spanish Ranch in Independence Valley, Elko County, near Tuscarora.
