Who Invented the Teleprompter?

Who invented the teleprompter? Three people in 1948, and the machine they made looked nothing like the glass rig at a news desk today. A teleprompter is a prompting device that shows a speaker their script; that first machine was a cut-out suitcase holding a roll of butcher paper, cranked by a technician like a mechanical cue card. The Smithsonian and HISTORY both tell the same story, and it starts with a performer, not a producer.

The origin: an actor who forgot his lines

The idea came from Fred Barton Jr. — legally Fred Barkau — a Broadway actor moving into television. The transition was hard: live stage work meant the same lines every night, while live television required a new script every day. As media historian Christopher Sterling of George Washington University put it, for performers coming from theatre or film, "the transition to television was difficult, because there was a much greater need for memorizing lines."

Barton took the problem to Irving Berlin Kahn, nephew of the composer and then vice-president of radio and television at 20th Century Fox. Kahn assigned his head of television research, engineer Hubert Schlafly. Schlafly's own verdict, recalled decades later in a 2008 interview with the Stamford Advocate, was characteristically blunt: "I said it was a piece of cake."

• Fred Barton Jr. (Barkau) — Broadway actor; had the problem, filed the patent.
• Hubert Schlafly — electrical engineer, joined Fox in 1947; built the machine.
• Irving Berlin Kahn — Fox television executive; funded it and commercialised it.

The prototype was startlingly crude: a large suitcase with one side cut out, weighing about 40 pounds, with a scroll of butcher paper inside. A patent application for the "television prompting apparatus" was filed on April 21, 1949, and granted on April 24, 1953. Sources differ on whether Barton or Schlafly is named as the filer, but not on the trio or the dates.

First live use: a soap opera in 1950

The device went on air on December 4, 1950, on the CBS soap opera The First Hundred Years. The show was scheduled at noon, which let Kahn and Schlafly run over from Fox on their lunch hour. 20th Century Fox had declined to manufacture the device — the executives were in the motion picture business — so the three left and formed the TelePrompTer Corporation around 1950.

They did not think of themselves as hardware sellers. As one account puts it, the founders saw the enterprise "not as a builder and seller of TelePrompTer machines, which they never patented, but as a service": they retyped scripts in oversized letters onto paper scrolls and ran the machines off-stage with trained company technicians. That detail matters later, when the cue is driven live by someone off camera.

First political use: Hoover, 1952

The breakthrough came at the Republican National Convention in Chicago, 1952, when former president Herbert Hoover used the machine for his keynote. Kahn personally instructed him on its use. According to Schlafly, Hoover went off script, panicked when the device stopped, and muttered, "Go ahead, TelePrompTer, go ahead." The press had no idea what he was saying — and worked out what he was using, which is what turned a novelty into a product.

The Smithsonian puts a number on the immediate impact: between the Republican convention and the Democratic gathering later that same month, 47 of the 58 major speeches were teleprompted. Schlafly later won an Emmy for a fully electronic version, and the company took another in 1999.

From paper roll to glass on the lens

The paper roll solved memory but did nothing for the camera, because the audience could see the scroll. The decisive change was putting the script in front of the lens on a screen reflected through beam-splitter glass, so the camera could shoot straight through it.

• Jess Oppenheimer, the writer, producer and director behind I Love Lucy, patented the first in-camera teleprompter, using a system of mirrors and glass to project the script directly in front of the lens. As Sterling describes it, once you could shoot through the glass, "the on-screen talent was looking straight at the audience."
• Luther George Simjian patented an in-camera teleprompter in 1955 as well, credited with making the reading more natural.
• Autocue Ltd, a British manufacturer founded in 1955, licensed Oppenheimer’s design — which is why the UK still calls any prompter an autocue.

Yale film and media scholar Neta Alexander, who has studied the device’s history, notes that Schlafly’s original design already included a mechanical speed controller "to align the script’s scrolling speed with the speaker’s delivery pace." That is the same idea as the words-per-minute control in every prompter since, including this one.

The physics of the modern rig is unchanged: low-iron glass at 45°, mirrored text, and a scroll speed matched to the speaker’s voice.

Why “teleprompter” and “autocue” both stuck

TelePrompTer Corporation’s brand name lost its capitalisation and became the generic noun, the way “Kleenex” did for facial tissue. It was an apt comparison: the TelePrompTer Corporation is a genericized trademark, and its founders built the first prompting machines without ever patenting the name. Across the Atlantic, Autocue licensed and built the in-lens design, so “autocue” became the British generic for the same device. A newsreader in London asks for the autocue; their New York counterpart calls the identical thing a teleprompter.

The company that outgrew its own product

There is a fitting irony in the ending. TelePrompTer Corporation stopped making prompters and became a cable television company: it spun off the prompting business in the 1960s, bought the Filmation animation studio in 1969, merged with H&B American in 1970 to become the largest cable company in the United States at the time, and was eventually absorbed by Westinghouse. It ended up in cable TV, defunct since 1981 — while the word it coined stayed in the vocabulary. Irving Kahn was convicted of federal bribery in 1971 and served 20 months; Schlafly, who was blameless in that, went on to help originate pay-per-view television and died in 2011, aged 91.

From 1950 to your browser

Seventy-five years on, the prompter is still the same optical trick. The paper roll is a phone, the off-stage technician is a web page, and the script is your own, kept in autosave. The free online teleprompter is a direct descendant of Barton’s suitcase — what changed is the screen; what still matters is the pace and the read.
