99% Invisible-108- Barcodes
from Roman Mars Hosted by Roman Mars
When George Laurer goes to the grocery store, he doesn't tell the check-out people that he invented the barcode, but his wife used to point it out. "My husband here's the one who invented that barcode," she'd occasionally say. And the check-out people would look at him like, "you mean there was a time when we didn't have barcodes?" A time without barcodes is hard to imagine now. But it wasn't that long ago, and the story doesn't start with George Laurer. It starts with an engineer named Joseph Woodland. In 1948 Woodland was trying to come up with simple symbol that, when scanned, would translate to a number that a computer could use to identify a product. Legend has it that he came up with his design while sitting on the beach in Miami. He was puzzling over the whole thing, thinking about Morse Code and tracing circles in the sand. When finally, bulls-eye! The very first barcodes were in the shape of a bulls-eye, though they weren't called "barcodes" yet. Woodland's invention was patented in 1952 as a "Classifying Apparatus and Method." But Woodland's "apparatus" would gather dust for 20 years —the scanners and other equipment needed to put the system in place were too expensive. Finally, in 1973, a group of supermarket executives led by Alan Haberman decided they needed to get some kind of scannable symbol in place to move people through checkout lines faster. They laid out a list of specifications that their ideal symbol would have and asked 14 companies, including IBM, to come up with a solution. That's where George Laurer comes into the story.
