Clarence Saunders was born in 1881. He was one of the most influential grocers of the 20th century whose impact is still felt today. His first great breakthrough came with the founding of his grocery store Piggly Wiggly in Memphis, Tennessee. His store was a break from tradition and introduced many innovations centered around the new concept of self-service. Prior to that time grocers would collect the groceries for the customer and return with them to ring up the sale. Saunder's store instead allowed the customer to collect their own goods and then bring them to the register using shopping baskets. One of the keys to his success was the layout of the store which forced customers to view everything on sale, giving birth to impulse grocery shopping.
After a risky stock gamble failed, Saunders left Piggly Wiggly, bankrupt. Saunders started another grocery store but it went bankrupt during the great depression. He started work on an automated grocery store, but stopped that and made wooden toys during WWII. Afterwords he founded Keedoozle which was a fully automated store, reminiscent of modern vending machines. Customers would use punch-tape to select merchandise, and then after paying for it the goods would be delivered via conveyor belt, but it was unreliable and failed in 1949.
Then until his death in 1953 he worded developing plans for Foodelectric which was the pioneer concept for today's self-checkout system. He described it as,
"The store operates so automatically that the customer can collect her groceries herself, wrap them and act as her own cashier. It eliminates the checkout crush, cuts overhead expenses and enables a small staff to handle a tremendous volume... I can handle a $2 million volume with only eight employees."
His concept never saw realization due to his death, however his insights paved the way for today's grocery stores and the now ever popular self-checkout stands.
