Frank Winfield Woolworth (April 13, 1852 – April 8, 1919) was an American entrepreneur and the founder of F.
W.
Woolworth Company and the operator of variety stores known as "Five-and-Dimes" (5- and 10-cent stores) or dimestores, which featured a low-priced selection of 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 customers could examine what they wanted to buy without the help of a sales clerk.
