George G. Blaisdell founded Zippo Manufacturing Company in 1932, and produced the first Zippo lighter in early 1933, being inspired by an Austrian cigarette lighter of similar design. It got its name because Blaisdell liked the sound of the word "zipper" and "zippo" sounded more modern. On March 3, 1936, patent was granted for the Zippo lighter.
Zippo lighters became popular in the United States military, especially during World War II — when, as the company's website says, Zippo "ceased production of lighters for consumer markets and dedicated all manufacturing to the U.S. military." The Zippo at that time was made of brass, but as this commodity was unobtainable due to the war effort, Zippo turned to using steel during the war years. While the Zippo Manufacturing Company never had an official contract with the military, soldiers and armed forces personnel insisted that Base exchange (PX) stores carry this sought-after lighter.
After World War II, the Zippo lighter became increasingly used in advertising by companies large and small through the 1960s. Many of the early advertising Zippo lighters are works of art painted by hand, and as technology has evolved, so has the design and finish of the Zippo lighter. The basic mechanism of the Zippo lighter has remained unchanged.
