IBM and the 1964 World’s Fair

By Dag Spicer | April 16, 2014

Just a few weeks ago, we received an interesting donation to the Museum: a commemorative punched card from the IBM Pavilion at the 1964 World’s Fair. It’s a standard IBM punched card—a piece of card stock with holes (usually) punched into it to represent information. This one, however, was given to visitors to the IBM Pavilion who took part in an exhibit there on handwriting recognition and databases, or what an IBM brochure describing the fair called Optical Scanning and Information Retrieval. I’m just going to keep things easy and call it IBM’s This Date in History exhibit.

Here’s the front of the card:

As you can see, it has a special IBM World’s Fair logo on the left with the current date (5/29/1964) and a statement that reads: “The following news event was reported in the New York Times on the date that you requested.” This is followed by a date—which the visitor selects—and a news headline from that date.

The idea behind the card was to provide a keepsake record of one’s visit, and the experience was as follows: Visitors would write a date in history on a small card. The card was then fed into an “optical character reader” where the handwritten date was converted into digital form. In turn, this date information was fed into an IBM 1460 computer system. The computer would then look up a major news event from that date by accessing its database (stored on a disk drive) and print the result on the card. The answer was also flashed on a Times Square-style display at the exhibit. The news database came from the New York Times archive (hence all dates had to be post-1851, when the Times was founded).

Speaking of limits to dates, perhaps to show that even IBM could have a sense of humor, the exhibit and system programmers had predicted that sooner or later someone would enter a date in the future, just to try to stump the machine. In fact, it happened on the very first day of the fair and the commemorative card given to that visitor read: “The date you have requested was February 3, 1970. Since this date is still in the future, we will not have access to the events of this day for 2,133 days.”

Edwin Newman, as part of an hour-long critique of the fair, gives an excellent, if brief, demonstration of the exhibit (from 0:08 to 1:02).

Let’s now take a look at the back of the card:

As we can see, the back of the commemorative card describes in quasi-pictorial form the whole process behind the exhibit.

The optical character recognition system from the exhibit is described in an IBM brochure as “experimental” and the reader may have noticed by now that it is limited to numbers only—dates were submitted in the form “3-9-1861.” Recognizing only numbers is a much simpler computational problem to solve. But behind this specific exhibit is a serious effort by IBM to develop its expertise in handwriting recognition more generally. Why? Because the then-current method of converting large amounts of handwritten information was “one of the slowest steps in automatic data processing.” Typically, in 1964, data was manually typed onto punched cards. The idea here was to cut out this step by using the computer itself to read human handwriting.

It’s interesting to note in this case that, from the perspective of 50 years on, it is we who have adopted data entry as a normal part of life in order to co-exist with computers while handwriting seems a lost art and hopelessly inefficient for record keeping. In fact, more modern computer systems based on handwriting recognition have a long and not-too-successful history, but the problem they are trying to solve was the same: how to get information into machine-readable form.

Using handwriting recognition in the 1964 exhibit was particularly smart of IBM because it is a natural means of communication for humans and isolates the visitor from direct exposure to the physical workings of the computer. Both are comforting to a visitor and increase the likelihood that they will be receptive to the experience and carry positive associations about computers and IBM home with them. Many people chose their birthdays as the date to look up.

IBM had several other exhibits within its Eero Saarinen-designed ovoid building:

  • A “machine translation” exhibit that showed real-time translation of Russian-to-English text. Since 1964 was during one of the hotter eras of the Cold War, the acquisition of of Russian technical and scientific information, and its accessibility to Western scientists, was a national priority. In this exhibit, the Russian text was processed (translated) remotely over a dedicated data connection between the fair and a powerful IBM mainframe computer in Kingston, NY.
  • An animated puppet show on binary logic, featuring Sherlock Holmes and Watson, which reporter Edwin Newman described as “… delightful. Several cuts above some of the more elaborate efforts by the big corporations. It also taught me something about computers.” (starts at 6:00).
  • Two “nerdy” displays, one on statistics in which a normal distribution is demonstrated through the use of hundreds of balls and another on mathematical concepts.
  • The most popular exhibit at the pavilion was The Information Machine, an astounding special-purpose theatre experience with multiple screens and projectors and which had a pneumatically-controlled grandstand that raised the audience 50 feet off the ground into the heart of the ovoid. Watch the show presented by the Machine where its host tells the audience “a machine designed to allow me to give you a lot if information in a very short time” (starts at 31:10). There’s also a good view of the moving grandstand and other IBM exhibits (starts at 5:55).

As IBM sought to increase demand for computers, it needed to take the general public along with for the ride. Its job was made easier by positive prevailing economic conditions and a desire within industry and business to “automate” (which meant computerize). But efforts like the 1964 World’s Fair were a longer-term bet: that by introducing computers in the informal festival-like atmosphere of a fair, the computer would be seen as force for positive change, rather than the popular notion of computers as mysterious and, possibly, dangerous. About 185,000 people a day visited the fair during its two-year run. For a great number of those people who visited the IBM Pavilion (the second most popular stop at the fair), it was their first direct interaction with a computer of any kind, a fact of great cultural significance and one which we celebrate today with this simple punched card memento.
