On February 22, 1916, the Telluride Daily Journal reported the death of Mahlon D. Thatcher (age 76), commenting that he was "one of the most prominent and widely known men in Colorado" and "reputed to be Colorado's wealthiest citizen". His fortune was estimated close to $50 million. Thatcher had come to Colorado in 1865 lacking money and influence, but his business acumen enabled him to create a fortune which contributed to the foundation of economic prosperity in the West, from Chicago to the Coast. He was an official of numerous banking institutions throughout Colorado, New Mexico and Montana, and was highly regarded for his leading role in the industrial and financial growth of the Rocky Mountain region .
