Why are lifesavers called lifesavers?

In 1912, chocolate manufacturer Clarence Crane (Cleveland, Ohio) invented Life Savers as a “summer candy” that could withstand heat better than chocolate. Since the mints looked like miniature life preservers, he called them Life Savers. After registering the trademark, Crane sold the rights to the peppermint candy to Edward Noble for $2,900. Noble created tin-foil wrappers to keep the mints fresh, instead of cardboard rolls. Pep-O-Mint was the first Life Saver flavor. Since then, many different flavors of Life Savers have been produced. The five-flavor roll first appeared in 1935.
