BALTIMORE messengers are pulling their telegrams out of thin air. The city where Sam Morse sent the first telegraphic message over 100 years ago now has six Telecars, roving station wagons each equipped with two-way radio and a Telefax printer. When a message arrives, the dispatcher radios the driver to speed to the address. Then he wraps the message around a cylinder in the transmitter and facsimile is received in car en route.
Is this how you’ll get your newspaper In the future? Maybe, says Toshiba, the Japanese electronics firm that developed this facsimile receiver. It prints both sides of a sheet simultaneously, in six minutes. If mass-produced, the device would sell for an estimated $300.
The Man Who Made Radio Talk
And Gave the Movies a Voiceâ€”The Dramatic Story of Lee De Forest, Inventor of the Audion Tube
By FRANK PARKER STOCKBRIDGE
THE story of Lee De Forest, and of his long and bitter court struggle for possession of the basic patents on the audion tube, runs parallel to the history of radio. Like most great inventors, he has been maligned, ridiculed, baffledâ€”and all but beaten. Today he emerges victorious, vindicated in his. claim to be called the father of radio broadcasting. Here Mr. Stockbridge writes the drama of the timid, unsociable youth who set his face toward a goal and learned how to fight to win it. â€”The Editor.
TELEGRAMS IN CHINESE are being speeded for wartime communication between four of the most important cities of China by Telefax apparatus built by the Western Union Telegraph Company. Previously, the Chinese system of telegraphing has involved using a code number for each of the 9,000 characters employed in writing. On the receipt of such a telegram, it must be decoded by turning the numbers back into their corresponding characters. Such telegrams occasion delays that hamper the war effort. Since the Telefax apparatus electrically transmits in facsimile whatever is written on paper, there is no loss of time in either sending or reading the message. .

Coast-to-Coast Mail in 15 Seconds
A TV-like facsimile system will transmit mail between Chicago and Washington this fallâ€”with a nation-wide fax mail operation in the offing
By S. DAVID PURSGLOVE
REVOLUTION takes place this fall in the way Uncle Sam handles the mail. Letters mailed in Washington, D. C, will be delivered in Chicago, Ill., the same day â€”thanks to electronic transmission.
The Post Office Department will put into regular use in October a television-like facsimile system between these two cities and their suburbs. Within seconds after reaching one post office, a letter will arrive in another, hundreds of miles away.
“Mail Box” for Telegrams Transmits Messages
Telegrams are transmitted automatically by a photo-electric facsimile machine housed within a compact wall box, as shown above. Messages are written on special blanks, which are deposited in the telegraphic “mail box” through a slot. Here the blank is automatically wrapped around a transmitting cylinder and the message sent like a wire photograph.
This is a pretty remarkable invention for it’s time. A color, plain paper, fax machine from 1946 that used colored pencils to print the output. The resulting image looks a lot like a printout from my first color inkjet printer. Sending a 7×10″ picture in full color took about 15 minutes, which seems pretty damn reasonable to me.
Tune In a Painting

TAKE a good look at the front cover of this issue of your Popular Science Monthly. You are looking at something you have never seen beforeâ€”a picture that was transmitted by radio in one operation and imprinted on a sheet of ordinary paper.
This is known as color facsimile. It is the product of years of effort to transmit an image by wire or radio and reproduce it perfectly on ordinary paper at the receiving point. It was developed by Finch Telecommunications. Inc., of Passaic, N. J. Finch labels it “Colorfax.”
And it’s compact too!
As many as 180,000 words of printed matter can be transmitted and recorded within one hour through a new high-speed facsimile system. Photos and diagrams also can be transmitted to any distant point and recorded without photographic, chemical or drying equipment. The system, developed by Western Union, uses either radio beams or communications wires as a means of transmission. The sending operator slips the printed material into a transparent cylinder and closes the endgate of the cylinder. This starts the cylinder spinning at 1800 revolutions per minute, and a photocell acting with a pin point of light scans the material. At the receiving end, needlelike instruments “print” a copy of the material on a dry recording paper. At the conclusion of the message an automatic signal causes a knife to cut the facsimile copy from the roll of dry recording paper.
Television Will Carry the Mails
By DAVID SARNOFF
PRESIDENT, RADIO CORPORATION OF AMERICA
A twinkling beam of light records a picture thousands of miles away. It is facsimile transmission- an interesting feature of this authoritative article on the future developments of radio and television.
IN HIS struggle for new information, man has been reaching farther and farther into mysteries beyond his accustomed sphere; farther with the runner through the forest . . . farther with camel caravans across trackless plains . . . farther with ships into uncharted oceans . . . seeking speed, and relishing the advantages of new contacts. From the start, mankind has struggled for better communication.
The printout actually looks really good, though at 3 feet per hour it isn’t the most useful thing in the world.
Pictures by Radio
RADIO facsimile, the process by which pictures and printed matter are transmitted over the air for identical reproduction at the receiving end, is rapidly advancing as a new and valuable service of radio broadcasting. An experimental facsimile network has been established as part of the Mutual Broadcasting System, and already three important stations, WGN, WOR and WLW, are transmitting on regular schedule. Factory-made receivers of medium price are being produced by a large radio set manufacturer and are now advertised and sold by department stores.
