Born in England in 1770, Sarah Guppy was a mother of six children and an inventor. Among her inventions are caulking that made ships more seaworthy, a kitchen fire hood, a bed that transformed into a home gym, and a design for piling foundation that led to the creation of the suspension bridge.
She allowed her designs to be used for free, considering it a public service. She preferred so remain behind the scenes, stating, “It is unpleasant to speak of oneself—it may seem boastful particularly in a woman.”
