Detailed explanation-1: -Nancy Johnson lived in Philadelphia in 1843 when she filed for her patent for the first hand-cranked ice cream churn (US3254A). Her simple invention launched a “disruptive technology” that made it possible for everyone to make quality ice cream without electricity.
Detailed explanation-2: -In addition to teaching and missionary work Nancy was an inventor. She patented the first hand-crank mechanism for ice cream freezers in 1843. Her husband, Walter Rogers Johnson (1794-1852), was a scientist, serving as the first Secretary of the American Association for the Advancement of Science in 1848.
