Immediately, most individuals take their checkout expertise on the grocery store without any consideration. They push up their carts, unload their groceries and watch because the cashier scans merchandise after merchandise. It simply is sensible, a lot that older generations hardly bear in mind the times when merchandise had been stamped with costs to be rung up manually, and youthful ones hardly ever take into account a world the place that was the norm.
That is as a result of the Common Product Code (UPC) — the barcode used on each product in grocery and retail shops all around the globe — modified every part 50 years in the past. Barcodes are scanned billions of instances every day, and award-winning engineer Paul McEnroe, who spent greater than twenty years in management roles at IBM, assembled and led the group that remodeled the know-how from an thought into the fact that endures.
However McEnroe’s position in creating the barcode hasn’t been absolutely acknowledged. The UPC’s unpatented know-how is within the public area, so McEnroe earns no royalties from the invention, and a fast Google seek for “who invented the barcode” turns up a Wikipedia web page lauding somebody named Norman Joseph Woodland.
So, what occurred?
It is a massive query that McEnroe is keen to reply in his memoir The Barcode: How a Group Created One of many World’s Most Ubiquitous Applied sciences, forthcoming from Silicon Valley Press on September 19.

Entrepreneur sat down with McEnroe forward of the memoir’s publication to study extra about how the UPC got here to be, the place the confusion over its inventor stems from and what recommendation he’d give younger leaders who wish to change the world like he and his group did so a few years in the past.
“We may provide you with some form of a logo to be learn optically or magnetically.”
It began in 1969. IBM needed to discover development alternatives and purchase startups, however the firm was informed it would not succeed. “Everyone necessary, all of the inventors and so forth, are going to stop the following morning as a result of they do not need the white shirts, blue coats, pink ties and black wingtip footwear that was the tradition of [IBM at] the time,” McEnroe says.
Decided to innovate regardless of that status, IBM “determined to color an imaginary pink line” round a part of the corporate and cost McEnroe with main it — so he did. The Dayton, Ohio native grew up “within the shadow of the Nationwide Money Register Firm,” which had a monopoly on checkstands worldwide, and he knew there was a greater option to do the “massive, outdated, cast-iron money register’s job.”
Folks within the grocery store and retail sectors agreed. There was a typical chorus: We have to do a greater job of stock management. We’re spending an incredible sum of money. Marking the value on each merchandise within the retailer takes plenty of time, and as quickly as we mark the costs, they’re improper.
McEnroe was nicely conscious of applied sciences that might tackle the issue. “We may provide you with some form of a logo to be learn optically or magnetically,” McEnroe says. He and his group would do each — although the optical one “has taken off probably the most.”
The just lately invented laser supplied a directional and constantly distributed gentle supply, and McEnroe was accustomed to the know-how, having used it in earlier initiatives. The low-cost, low-power, protected choice provided a chance to make progress on the UPC.

“So, I went to [IBM], similar to you’ll go to a enterprise capitalist in the present day in Silicon Valley or Boston or wherever, and I proposed that we go after this enterprise,” McEnroe recollects, “that we construct tools that would slot in the shops, stock tools that will sit in a warehouse and management tools that will sit on the headquarters. And it might all work collectively.”
The know-how would use merchandise identification for automated reordering and itemizing on the show and money register slip, that includes the title of the product bought, how a lot it value and another mandatory info.
McEnroe requested three years of funding from IBM: $300,000 for the primary yr, $1,000,000 for the second, and $3,000,000 for the third. The corporate agreed and requested McEnroe to do the job in North Carolina, the place it had simply constructed a plant that wasn’t but stuffed with manufacturing tools. So McEnroe made the transfer and employed six folks for his group.
“I feel it has been superb for society as a result of no one has needed to pay something for the usage of the code.”
The next yr, in 1970, the Nationwide Affiliation of Meals Chains (NAFC) shaped a committee to look at the issue of merchandise identification, hiring consulting firm McKinsey to assist it achieve this. By 1971, McEnroe and his group had developed their code, and in 1972, the grocery store committee requested all firms to current proposals for the way they might automate supermarkets, together with merchandise identification.
Those that submitted codes needed to conform to donate them to the general public area earlier than they could possibly be accepted, which meant no patents or royalties for his or her inventors. Because of this, McEnroe and his group did not count on to see any cash from the UPC. “That is the way in which it is labored out,” McEnroe says. “I feel it has been superb for society as a result of no one has needed to pay something for the usage of the code.”
McEnroe and one other group member named Jack Jones share the patent on the pistol-grip handheld barcode scanner, although they do not earn any royalties from it both. “So far as I do know and a minimum of throughout my time, when engineers signed on with IBM they signed all of the rights to any patent they might do whereas working for the corporate to the corporate itself, so IBM owns the patent not the inventor,” McEnroe explains.
In 1973, the committee selected McEnroe’s group’s code and proposal, and so they shipped the primary merchandise out in 1974, although solely to 5 supermarkets. It took a number of years to “obtain an inexpensive quantity,” McEnroe recollects. At that time, he left this system to work in a distinct a part of the corporate. By the early Nineteen Eighties, the UPC had exploded.

“[It] could not have misreads and cost folks the improper worth. That was the largest single drawback.”
Naturally, McEnroe and his group got here up in opposition to some vital challenges through the UPC’s improvement and launch. They needed to create a code that was “sturdy” sufficient to be learn by way of plastic, which could possibly be compromised by the way in which gentle shone, frost or any variety of different elements. It needed to work when it was pulled throughout the checkstand shortly and never essentially held flat.
“You did not need the operator to even must see the code,” McEnroe explains. “If she is aware of the codes are sometimes on the underside of packages, pulls the package deal throughout, would not even have a look at the underside of the package deal. So it needed to be very dependable. [It] could not have misreads and cost folks the improper worth. That was the largest single drawback.”
It took McEnroe and his group two years to construct the self-correcting code that might repair itself robotically in real-time.
Different “extraneous technical issues” arose too — How you can ship the sign from the entrance of the shop to the again effectively? — however McEnroe says one of many largest, surprising issues was really the know-how’s public reception. “[There was] the social drawback of individuals and organizations coming to grips with the truth that the value [was] not on the merchandise,” McEnroe explains.
“Labor unions had been afraid that they had been going to lose checkstand operator positions.”
The backlash was so excessive that the UPC’s public unveiling in 1974 did not go as deliberate. McEnroe’s chief engineer known as him to say the shop could not open. McEnroe was shocked; they’d checked the know-how so typically, and it was so dependable. Nevertheless it wasn’t a technical failure: It was a picket line.
“Labor unions had been afraid that they had been going to lose checkstand operator positions,” McEnroe says. “So that they picketed the shop, after which 18 states handed legal guidelines in opposition to taking the value off of the merchandise or legal guidelines that made it so when you had a scanner within the retailer, you could not take the value off your merchandise.”

McEnroe needed to journey across the nation to clarify the know-how’s advantages and security, as operators might need to face over the lasers for years. McEnroe knew the know-how was protected; he’d introduced monkeys from Africa and examined them at Stanford Analysis Institute.
“And naturally it was protected as a result of A, [the laser] did not come out the window, besides hardly ever, and B, we had proved that if it did come out the window and so they checked out it for a number of years, it nonetheless would not damage them,” McEnroe says.
“I had identified his title as a result of I had studied the historical past of the codes. And his title was Joe Woodland.”
McEnroe constructed and led the group that developed the UPC, which grew to become broadly utilized by the Nineteen Eighties and nonetheless is. However when you Google “who invented the barcode,” McEnroe’s title is scarcely seen. As a substitute, a Wikipedia web page cites Norman Joseph Woodland and Bernard Silver because the know-how’s co-creators.
Why? It began with the ring of a phone.
After he and his group got here up with their code, McEnroe obtained a name from one other IBM worker based mostly in New York. “I had identified his title as a result of I had studied the historical past of the codes,” McEnroe says. “And his title was Joe Woodland.”
On the decision, Woodland reiterated that he’d invented a bullseye code for supermarkets in 1948. The code was patented in 1952, per the Smithsonian. By 1973, the Radio Company of America (RCA) owned the patent and was certainly one of 14 firms that submitted a code to the committee for consideration, McEnroe recollects.
However there was one main challenge with Woodland’s code, McEnroe says: It did not work nicely sufficient for grocery store and retail adoption.
In line with McEnroe, Woodland knew it, too. “I’ve studied the code that your group has provide you with, and I do know my code, and your code is so significantly better that there is not any comparability,” McEnroe remembers Woodland telling him over the cellphone. “I wish to be a part of your group. I might like to dwell in North Carolina and give you the results you want and be your interface and your advertising particular person to market your code to the world.”
Gee, what could possibly be higher than having the man who invented the primary grocery store code — however one that did not work and had by no means been carried out — in your group? McEnroe thought.
McEnroe did rent Woodland, who moved right down to Raleigh and spent the remainder of his profession engaged on the UPC mission. McEnroe acknowledges that Woodland invented the primary grocery store code however maintains that “Wikipedia simply obtained it improper.” “[Woodland’s code] was by no means utilized in any quantity in any respect,” he explains. “Simply within the take a look at retailer that Kroger did in Cincinnati. I went and visited that retailer and noticed it did not work both. And we examined it six methods from Sunday.”

“I do not know what he informed them. No matter he informed them, they really gave him the Medal of Know-how.”
So why do most inquiries into the barcode’s creator lead again to Woodland? McEnroe says George H.W. Bush’s presidential run in opposition to Invoice Clinton performed a major position.
On the time, about 20 years after the UPC’s improvement, Bush was “not seen as coupled with the fact of the American housewife,” McEnroe says. Most individuals had been utilizing the know-how for greater than a decade; to current a relatable entrance, Bush partook in a demo run by the Tremendous Market Institute in Florida, “the place a grocery store had been artificially arrange within a conference middle.”
Bush had an opportunity to make use of a scanner on the code for the primary time. “So he obtained his image taken, scanning objects, and he mentioned, ‘That is superb. It is the best know-how I’ve ever seen — who invented this factor? And so they mentioned, ‘Nicely, we do not know. Any person from IBM,'” McEnroe says.
Bush informed them to search out out who it was as a result of he needed to present them the Nationwide Medal of Know-how. When his folks known as the grocery store committee, they got the unique proposal put collectively by Woodland. “That is the very first thing I might requested Woodland to do as a advertising man — not an inventor of our code, however a advertising man — to write down the proposal for the barcode,” McEnroe explains.
Woodland wrote the proposal, and his contact info was on the again in case anybody had questions. The engineering group had already been disbanded; Woodland, nearing retirement, was the final one engaged on the barcode. “I do not know what he informed them,” McEnroe says. “No matter he informed them, they really gave him the Medal of Know-how.”

The Bush-Clinton race would additional solidify the narrative of Woodland because the barcode inventor. Because the tide turned in opposition to the incumbent, McEnroe recollects that the grocery store demo was written up within the information fairly a bit, and he started to acknowledge a sample within the telling of the know-how’s improvement.
Usually, one paragraph would say Woodland invented the primary grocery store code (“That is fairly true,” McEnroe admits). One other would describe Woodland’s position in advertising and promoting the code McEnroe and his group created later.
“What he would not say is that in between the 2, his code wasn’t used for years and years,” McEnroe says. “And the opposite code was taken because the nationwide normal. And it is the one that everyone’s utilizing. So the one which he promoted and the one which he was the advertising man for was profitable. And that’s the common product code; that is the vertical bar code we now have in the present day. His authentic code did not go wherever.”
Woodland’s patent had already expired by the point the grocery store committee convened. “The IBM attorneys mentioned it did not even learn,” McEnroe provides. “The entire methodology of deciphering how broad a black bar is in a white house is dramatically totally different. It is a technical factor, but it surely’s dramatically totally different in our code [than] it was in [Woodland’s] round code.”

“It is a story that…offers you concepts about the way you go about issues to today.”
McEnroe acknowledges there’s “plenty of misunderstanding about who did what with the code” — and says ‘”it was time to get that corrected.” That is why, 50 years after the UPC’s improvement, the engineer is publishing his memoir to assist set the document straight. The e-book contains an appendix with paperwork that refute sure claims, like the misunderstanding that IBM got here up with the UPC in just some weeks.
“There are a pair books which have been written by the Tremendous Market Institute about incorporating [the UPC] into the grocery store itself and the way it affected that,” McEnroe says. “However this can be a story that exhibits not solely that, but in addition the way it was created — it offers you concepts about the way you go about issues to today.”
McEnroe says he and his group thought the UPC would possibly final 20 or 30 years, not so long as it has. However the UPC solved an issue that society was combating for a while, made checkouts work extra effectively, and was dependable and simple to implement — all issues he believes contribute to a know-how’s longevity. Even QR codes, which permit scanning in two instructions for extra information, are a variation of McEnroe’s code.

Not surprisingly, McEnroe is commonly requested for his recommendation to younger professionals who wish to change the world. And maybe crucial factor, alongside a specific amount of luck and persistence? Preserving an open thoughts, McEnroe says — however being “disciplined in your curiosity.”
“Fifty years in the past, it was quite a bit more durable to grasp what was accessible on the earth,” McEnroe explains. “And these days, with the web, that is quite a bit simpler. Earlier than, you had nearly no selection however to be a degreed engineer, go to high school, examine on the college, go to the libraries. Now that will be effective, however you can also do an excessive amount of this work through the use of the web and simply looking issues up. However you need to watch out about what you search for. Is it proper, or simply one thing any individual else wrote down?”
Being a part of a group and recognizing that you could accomplish extra collectively than you possibly can by yourself can also be very important, as is sustaining these relationships alongside the way in which.
“Do not burn your bridges as you undergo life,” McEnroe says. “When you need to return and name upon folks, they are going to be joyful to come back and assist you once more. I had to do this so many instances, and all people that I known as upon to assist me was extraordinarily useful. As you are working with folks if you’re youthful, work with them nicely and depart style of their mouth, after which they will assist you afterward.”
