BEFORE THE TURN OF THE CENTURY, several entrepreneurs opened stores that would become some of the largest chains in the country. In 1852, Potter Palmer opened a dry goods store in Chicago, which eventually became Marshall Field & Co. In 1881, Joseph Lowthian Hudson opened his first store in Detroit, and in 1883, Barney Kroger established a grocery store in Cincinnati.

Sears began when Richard Sears started selling watches in 1886 to supplement his income, and later hired watchmaker Alvah C. Roebuck to join his venture. In 1887, David May opened the first store of what would become The May Department Stores Co. in Leadville, Colo. And in 1897, F.W. Woolworth first opened for business.

These stores opened as America gradually shifted from an agrarian-based to a manufacturing-based society. People had more free time and more income. Automobiles became affordable and people were mobile, making them eager to get out of their houses and go shopping.
