George Laurer: Architect of the UPC Barcode

Biography

George Joseph Laurer (September 23, 1925 – December 5, 2019) was an American electrical engineer and senior researcher at IBM, best known as the chief designer of the Universal Product Code (UPC) barcode. While he did not invent the barcode itself, he was the pivotal figure who transformed it from a laboratory concept into a global commercial standard — earning the reputation as “the man who brought barcodes into the marketplace.”

Laurer was born in New York City and grew up in Baltimore, Maryland. As a teenager, he contracted polio but recovered and later enlisted in the U.S. Army during World War II. After his service, he first studied to become a radio and television repair technician, but with encouragement from his instructor, he pursued formal engineering studies. He graduated in 1951 from the University of Maryland, College Park with a degree in electrical engineering.

After graduation, Laurer joined IBM, where he worked for 36 years, rising from junior engineer to senior researcher. In 1969, he transferred to IBM’s Research Triangle Park in North Carolina, where he led the development of the UPC barcode. Over his career, he earned 28 U.S. patents and published 20 technical bulletins, with research spanning automatic identification, census equipment, and standardized testing systems. His most influential achievement, however, was the UPC barcode system.

He retired from IBM in 1987 but continued consulting in automatic identification and spent years debunking myths about barcodes. He was inducted into the National Inventors Hall of Fame and recognized as one of the founders of modern retail automation. Laurer passed away in North Carolina in 2019 at the age of 94.

The Story of the UPC Barcode

By the late 1960s, U.S. supermarkets faced major efficiency problems: checkout was slow and error-prone because cashiers had to manually enter prices, and inventory management relied on manual stock counts. To solve this, the grocery industry formed the “Ad Hoc Committee for a Uniform Grocery Product Code” in 1970, calling for a machine-readable product identification standard.

IBM entered the competition with George Laurer as project lead. Initially, he was tasked with proving the feasibility of RCA’s popular “Bull’s-eye” circular barcode. But after careful study, Laurer concluded the design had fatal flaws: high-speed printing caused ink to spread, distorting the circular rings and making scanning unreliable. He refused to endorse a solution he didn’t believe in and instead designed a rectangular linear barcode — the foundation of the UPC.

To prove its reliability, Laurer’s team built a prototype laser scanner and staged a dramatic demonstration: a company baseball pitcher hurled ashtrays printed with barcodes across the scanner, simulating fast-moving products at checkout. Each barcode was read flawlessly, convincing IBM leadership to back the new design.

After rigorous industry evaluations, including independent testing at MIT, Laurer’s rectangular code was chosen in 1973 over RCA’s circular design. The UPC debuted publicly on June 26, 1974, when a pack of Wrigley’s Spearmint Gum was scanned at a Marsh supermarket in Troy, Ohio — the first product ever checked out using a barcode.

Why the UPC Design Succeeded

Laurer’s design triumphed not because it was the most advanced, but because it was the most practical for mass production:

• Tolerance for printing errors: Vertical bars could withstand ink spread without distorting width ratios, meaning manufacturers didn’t need expensive new equipment.
• Efficient coding structure: A UPC-A code used 12 digits with a check digit to prevent silent errors. Guard bars at the start, middle, and end improved scanning speed, while the limited set of bar widths made decoding simple and cheap.
