Michael Beshoar was a schoolmate of the Thatcher brothers in Pennsylvania, then graduated from the University of Michigan School of Medicine and moved to Arkansas, where he ran a medical practice until the start of the Civil War. He joined the Confederate Army as a surgeon, but after he was captured by the Union Army he then served that army also as a surgeon. After the war, Beshoar settled in Pueblo where he established a medical practice, Pueblo’s first drug store and its first newspaper, a weekly named The Chieftain, which he sold a year later. He had been commuting weekly between Pueblo and Trinidad, running medical practices and drug stores in both cities, but eventually settled full-time in Trinidad, where he practiced medicine, owned several businesses, including a coal mine, and founded his final newspaper, the Trinidad Advertiser, a morning daily that he edited for many years.
