How did the candy called "Life Savers" get that name?

Invented in 1912 by Clarence Crane, a chocolate maker who wanted a sweet product that wouldn't melt in the summer heat...he decided on a peppermint hard candy in the shape of a cirle with a hole in the middle...since they looked like miniature life preservers, he called them Life Savers & registered the trademark...the 1st flavor was Pep-O-Mint in 1912.

"Candy manufacturer Clarence Crane of Garrettsville, Ohio,[1] (father of the poet Hart Crane) invented the brand in 1912 as a "summer candy" that could withstand heat better than chocolate.

The candy's name is derived from its similarity to the shape of life preservers used for saving people who have fallen from boats."
