Television's Long-Distance Debut: Hoover on the Screen, 1927
On April 7, 1927, AT&T's Bell Laboratories publicly demonstrated long-distance television, sending live images and voice of Commerce Secretary Herbert Hoover from Washington to New York.
The face on the little screen was barely two inches wide, flickering and ghostly — but it was live, and it was more than 200 miles away.
On April 7, 1927, several dozen newspaper reporters and officials of Bell Telephone Laboratories gathered in an auditorium in midtown Manhattan to witness the first American public demonstration of long-distance television. In Washington, D.C., Secretary of Commerce Herbert Hoover sat before a strange apparatus of spinning disks and bright lights. His picture and voice traveled together over telephone lines to New York, where the audience watched his face appear on a rectangular screen about 2 by 2.5 inches — and heard him speak through a loudspeaker.
"Today we have, in a sense, the transmission of sight for the first time in the world's history," Hoover told the audience, looking into the transmitter. "Human genius has now destroyed the impediment of distance in a new respect, and in a manner hitherto unknown." He was speaking to Walter S. Gifford, president of AT&T. The audio ran both ways, but only the New York audience could see — the pictures traveled one direction only.
The system was the work of Dr. Herbert E. Ives, Frank Gray, and a team of more than 50 Bell Labs engineers. A flying-spot beam of light swept across the subject, and a 50-aperture spinning disk scanned the image at roughly 16 to 18 pictures per second. The demonstration ran on two paths at once: a copper-wire link from Washington to New York, and a radio link from an experimental station at Whippany, New Jersey. Viewers said they could detect no difference in quality between wire and wireless. A second, larger receiver showed the same flickering image on a screen 24 by 30 inches. Telephone operator Edna Mae Horner, who helped guests in Washington exchange greetings with New York, is remembered as the first woman ever seen on television.
The press was dazzled. The New York Times put the story on the front page under the headline "Like a Photo Come to Life," though it added the caution "Commercial Use in Doubt." A United Press report marveled that "the eye as well as the voice now can be flung through space." A few weeks later, on May 23, nearly 600 members of the engineering societies watched a repeat demonstration in New York.
Commercial use was indeed doubtful — and never arrived for this system. The Bell Labs television was mechanical, built on spinning disks, and within a few years electronic television would sweep it aside entirely. But April 7, 1927, proved the essential point: moving pictures could be sent across a continent's wires, in step with sound, in both directions. The two-way television telephone the engineers showed off would take nearly a century to become the video call in everyone's pocket.
Why it matters: every video call, every live broadcast, descends from this afternoon — the day sight first traveled by wire, and a flickering two-inch face of a cabinet secretary showed the world what television could be.
