The Q-tip was invented in the 1920's by Leo Gerstenzang (a Polish-born American). His wife had used a toothpick with cotton stuck on the end to clean their baby's ears, and Leo invented Q-tips to replace her jury-rigged invention. Gerstenzang's original Q-tips consisted of a wooden stick swathed in cotton at both {ends;} much later, the wood was replaced by white cardboard. Gerstenzang started the Infant Novelty Company to sell Q-tips (which he then called Baby {Gays);} in 1926, he changed the name of his product to Q-Tips Baby Gays. The Q stood for 'quality'. Eventually, the name changed to Q-tips. Doctors today advise that you should not use Q-tips to clean inside your ears. Q-tip, however, have many other uses, including cleaning small areas (like jewelry or the space between computer keys), applying glue, spreading paint, etc.
