Senator T. C. Power met A. C. Johnson in Chicago and offered him a job out west, bringing the nineteen-year-old to work as chief clerk at Power’s Fort Benton Mercantile in 1879. Power and Johnson became friends and both moved to Helena in 1890. Johnson went on to direct Power’s American National Bank and its successor, the First National Bank of Montana, earning the admiring nickname “dean of Montana bankers” and holding that a banker’s responsibility was to those who trusted him with their money. Built in 1892, his home reflected the image he cultivated for his financial institutions: strong, fortresslike, and invincible. Its Romanesque style, with a castle-like tower, round-arched entryway, and rough granite blocks, expressed that intention well. Banker Henry Hale Piggott and his family were living there by 1927 and raised their three daughters in the house. In 1956, the Episcopal diocese bought the residence, which then became home to several Episcopal bishops, and the “9 Cross” in the porch’s wrought ironwork, the diocese’s registered livestock brand, recalls that ownership.
