"When Reuben and Austin began to produce roasted coffee there were at least twenty-five other companies already engaged in some form of coffee production and distribution in San Francisco including, of course, the well-known Folger Company started by William Bovee (which began in San Francisco thirty years earlier). Most of these coffee businesses were started by family groups which contributed to the growth of San Francisco. San Francisco in the nineteenth century was ripe for the importing and roasting of coffee. The foundation for commercial production of coffee dated back to the 1820s when English planters brought coffee to Costa Rica. By the early 1840s German and Belgian planters followed with coffee plantations in Guatemala and El Salvador, two of the several Central American countries where Hills Bros. would obtain its mild coffee beans. During the Gold Rush (1849) San Francisco rapidly expanded and grew. Coffee was imported and sold, after roasting, to restaurants and hotels. Yankee gold miners and others without equipment to roast and brew their own coffee, populated "coffee houses."In 1873, two brothers, Austin Herbert and Reuben Wilmarth Hills arrived in San Francisco from their home in Rockland, Maine with their father Austin who had come to California some years earlier. Five years later in 1878 A. H. and R. W. Hills established a retail stall to sell dairy products in the Bay City Market under the name of their new partnership Hills Bros. Their small business expanded in less than four years with the acquisition of a retail coffee store titled Arabian Coffee & Spice Mills on Fourth Street in San Francisco. In two more years (1884) still larger quarters were occupied at Sacramento and Sansome Streets."
