    Historical Note

    Key figures in the banking history of Tucson and Tombstone, Barron and Lionel Jacobs initially began their financial careers as merchants and suppliers. In 1867 they partnered with their father, Mark Israel Jacobs, to expand the family’s mercantile business, the Mark I. Jacobs Company, from San Bernardino to Tucson. Mark Jacobs was a Polish-born Jew who worked as a men’s clothing retailer in England before moving his family to California, settling first in San Diego in the 1850s and later in San Bernardino and San Francisco. Lionel (1841-1922) and Barron (1843-1936) were his two oldest sons and eventually became the patriarchs of the Barron family.
    The Arizona branch of the Jacobs enterprise flourished and in 1869, Mark I. Jacobs moved to San Francisco to coordinate the company’s purchase and shipment of merchandise to Arizona. By 1871, Lionel and Barron began to offer financial services in addition to their mercantile business including exchanging gold coin for paper money, providing short term loans, holding savings deposits, redeeming checks and drafts, and collecting payments for settlers in Tucson, Tombstone, and surrounding areas.
    The Tucson population and economy boomed in the mid 1870s, especially after the arrival of the Southern Pacific Railroad, and the Jacobs brothers’ enterprises expanded. By 1875 the firm had become one of the largest mercantile establishments in Arizona Territory and the brothers renamed it Lionel M. Jacobs and Company. In 1879 they partnered with Phillip William Smith to open the Pima County Bank, the first formal financial institution in Tucson. In 1880 Smith and the Jacobs expanded their business by opening the Agency Pima County Bank in Tombstone (they changed the name of this institution to the Cochise County Bank in 1881). Both banks did well - the Pima County Bank won a banking war with several Tucson competitors and became the First National Bank of Tucson in 1882. The bank later evolved into the Bank of Tucson, the Consolidated Bank of Tucson, the Arizona National Bank, and the current Valley National Bank.
    Along with their financial success the Jacobs brothers also achieved political success. Lionel was appointed to the Pima County Board of Supervisors in 1871. He was also elected to the territorial legislature and served on the Tucson city council. Both Lionel and Barron also served as treasurer for the territorial legislature.
    As their business expanded it came to involve or employ increasing numbers of their family members, including their younger brother Albert Ephraim, their nephew Abraham Franklin, their uncle Jacob Philip Solomon, and their brother-in-law Marcus Katz.
