One of the first shopping carts/trollies was introduced on June 4, 1937, the invention of Sylvan Goldman,owner of the Humpty Dumpty supermarket chain in Oklahoma. One night, in 1936, Goldman sat in his office wondering how customers might move more groceries.
He found a wooden folding chair and put a basket on the seat and wheels on the legs. Goldman and one of his employees, a mechanic named Fred Young, began tinkering. Their first shopping cart was a metal frame that held two wire baskets. Since they were inspired by the folding chair, Goldman called his carts "folding basket carriers".
In the United States, 24,000 children are injured each year in shopping carts/trollies.
