Dr Harry Campbell

The London physician whose work on chewing led to Bickiepegs.

Who he was

Dr Harry Campbell was a London physician and Fellow of the Royal College of Physicians. He qualified at St Bartholomew's Hospital, spent over 20 years as physician and pathologist at the North-West London Hospital, and worked at the West End Hospital for Nervous Diseases. He later edited the Medical Press and Circular.

He noticed food was getting softer, and believed little jaws needed more to do. In 1903 he made the case in The Lancet, in a series called Observations on Mastication: babies should have something firm to chew.

In 1925, he turned that idea into something parents could use: a simple, hard biscuit made for babies to gnaw. Bickiepegs were born.

What he believed

“…during the years of development, [food] should be taken in forms which compel adequate mastication, such as stale bread, bread-crusts, and hard biscuits.”

Why it still matters

Today, researchers are looking again at how chewing shapes growing jaws. Dr Campbell's answer, back in 1903, was simple: let babies chew more. Over 100 years on, that's still what Bickiepegs are for. And once teeth come through, a gentle first brush too.
