Ann Turner Cook, whose cherubic newborn face was dubbed "the original Gerber baby" around the world, has died. She died at the age of 95.

Cook's death was confirmed by Gerber in an Instagram post on Friday.

Her grin and expressive curiosity stole hearts everywhere many years before she became a wonderful mother, teacher, and writer, and will continue to live on as a symbol for all newborns," the business added.

Cook was 5 months old when a neighbour, artist Dorothy Hope Smith, made a charcoal sketch of her, which was later entered into a contest held by Gerber for a national baby food marketing campaign.

The image was so popular that it was adopted as the company's trademark in 1931 and has since been featured on all packaging and advertising.

The identity of the infant, however, was kept hidden for decades, leading to suspicions about who it was, with Humphrey Bogart and Elizabeth Taylor among the suspects.

It was eventually found to be Cook, who went on to become an English teacher in Tampa, Florida, and later a mystery author, in the late 1970s.
