Frank Winfield Woolworth, American businessman, founded the F. W. Woolworth Company (d. 1919)
Frank Winfield Woolworth (April 13, 1852 – April 8, 1919) was an American entrepreneur, the founder of F. W. Woolworth Company, and the operator of variety stores known as "Five-and-Dimes" (5- and 10-cent stores or dime stores) which featured a selection of low-priced merchandise. He pioneered the now-common practices of buying merchandise directly from manufacturers and fixing the selling prices on items, rather than haggling. He was also the first to use self-service display cases, so that customers could examine what they wanted to buy without the help of a sales clerk.
