There are several theories behind the origin of the product's name. One theory refers to Mark Pringle, who filed a US Patent 2,286,644 titled "Method and Apparatus for Processing Potatoes" on March 5, 1937. Pringle's work was cited by P&G in filing their own patent for improving the taste of dehydrated processed potatoes. Another theory suggests that two Procter advertising employees lived on Pringle Drive in Finneytown (north of Cincinnati, Ohio), and the name paired well with "potato chips". Another theory says that P&G chose the Pringles name from a Cincinnati telephone book. Another source says that the name Pringles was "chosen out of a hat" to promote a family name appeal.
