Albert Americus Rich was born on November 8, 1845 in New York state and came to Montana in 1872. Ten years later, Rich bought a small ranch located 560 yards northwest from the Hunters Hot Springs town site. Eventually, Rich expanded the ranch to over 1,000 acres and he and his family lived on this ranch long past the turn of the 20th century.

During the 1890s, A. A. Rich was appointed Commissioner of Roads and Bridges in an area of Park County which included Hunters Hot Springs. According to Rich family archivist Sharon Pohlman, there is a written family history footnote that says A. A. Rich "worked for the railroad" which could explain the railway-style headgear he is wearing in the group photo.
