Universal Product Code inventor dies at 94

According to a recent article published on NPR, IBM engineer George Laurer has passed away at the age of 94. Laurer is most famous for creating the universal bar code now used across the world for retail packaging.

On a June morning in 1974, a Marsh Supermarket cashier in Troy, Ohio, rang up a 67-cent pack of Juicy Fruit chewing gum using something novel — the black and white stripes of a universal bar code.

The Universal Product Code is now a packaging mainstay on everything from cereal boxes and produce to electronics and airplane tickets, but it might not have worked without IBM engineer George Laurer.

Laurer, who died this month at 94 in North Carolina, had been given an assignment by his manager: Write a proposal for grocery executives explaining how IBM would take a previously invented bar code pattern, in the shape of a bull's-eye, and make it work in supermarkets across the country.

But when that manager returned from a vacation, Laurer was there to meet him. "I didn't do what you asked," he said.

Instead, Laurer had created something else — the bull's-eye was gone and in its place was a linear bar code. Laurer had deemed the bull's-eye design unworkable. The circular code, inspired by Morse code and patented by N. Joseph Woodland and Bernard Silver in 1952, was too small, and it would smear when run through the poor-quality printing presses used for most food labels at the time.
