R. G. Robertson

R. G. Robertson served as a U.S. Marine Corps officer in the Vietnam War from late January 1968 until February 1969. After completing his military service, he earned an MBA from the University of Michigan. During nineteen years in the investment business, he was a partner at Hambrecht & Quist and later a self-employed options market maker on the Pacific Stock Exchange in San Francisco.

In 1990, he and his wife, Karen, moved from the Bay Area to Sun Valley, Idaho, where he began writing about mountain men and the fur trade. In researching his books, the couple drove thousands of miles across the western United States, visiting the sites where Beyond the Yellowstone and R. G.'s other books take place. In 1999, they relocated to Scottsdale, Arizona, where they live today.

In addition to writing, R. G. enjoys mountain climbing, hiking, skiing, biking, movies and traveling the American West.
