On August 6, 1840 Benjamin Gallagher was born in Pleasant Grove, Iowa to Lavinia Zion and George Gallagher. In 1862 he moved to the Nebraska Territory where he was appointed as post trader at Fort McPherson and later to Cheyenne in the Wyoming Territory. On May 25, 1869 he served as one of the Grand Jurors on the first court of Cheyenne and later ran as a member of the People's Party for city council before joining the Democratic Party.[1] He was appointed as Auditior of the Territory by Territorial Governor John Allen Campbell and took the oath of office on December 11, 1869 and served until June 4, 1870. He later moved back to Omaha, Nebraska and in the 1890s became a supporter of the free silver movement.[2]
