the center, and Crane named the candy after its resulting life preserver shape. In 1913, Crane sold the formula for his Life Savers candy to Edward Noble of Gouverneur, New York for $2,900. Noble started his own candy company and began producing and selling the mints known as Pep-O-Mint Life Savers. He also began to package the mints into rolls wrapped in tin foil to keep them from going stale. This process was done by hand until 1919 when machinery was developed by Edward Noble's brother, Robert Peckham Noble, to streamline the process. Robert was a Purdue-educated engineer. He took his younger brother's entrepreneurial vision and designed and built the manufacturing facilities needed to expand the company. The primary manufacturing plant for Life Savers was located in Port Chester, New York, a local landmark replete with a Life Savers motif cast into the cornice. Robert led the company as its chief executive officer and primary shareholder for more than 40 years, until selling the company in the late 1950s. By 1919, six other flavors (Wint-O-Green, Cl-O-Ve, Lic-O-Rice, Cinn-O-Mon, Vi-O-Let and Choc-O-Late) had been developed, and these remained the standard flavors until the late 1920s. In 1920, a new flavor called Malt-O-Milk was introduced. This flavor was received so poorly that it was discontinued after only a few years. In 1925, the tinfoil was replaced with aluminum foil. Noble promoted the candy at the cash registers of saloons, cigar stores, drug stores, barber shops, and restaurants. He had the candy placed, with a five-cent price, near the cash register. In 1921, the company began to produce solid fruit drops. In 1925, technology improved to allow a hole in the center of the fruit candies. These were introduced as the "fruit drop with the hole" and came in Orange, Lemon and Lime, each of which were packaged in their own separate rolls. In contrast to the opaque white mints previously produced by the company, these new candies were crystal-like in appearance. These new flavors quickly became popular with the public. Four new flavors were quickly introduced, namely, anise, butter rum, cola and root beer, which were made in the clear fruit drop style. Other than butter rum, which remains in the brand's lineup of flavors, these did not prove to be as popular as the three original fruit drop flavors. In 1931, the Life Savers "Cough Drop" was introduced with menthol, but
