When was the first transatlantic (between the UK and the US)
transmission of visual material, ie. a picture? Who / which company
made this transmission? What was the content?
This was probably through the cable in the ocean between the UK and the US.

Clarification of Question by can1972-ga on 30 Dec 2004 04:37 PST

Clarification: I am interested in the first transmission of a picture
for e.g. print purposes and not radio or television transmissions.
i.e. the first step from text messages to graphics.
Thank you for your interest.

"1926
A commercial radio link for facsimile working is opened between the
London office of the Marconi Wireless and Telegraph Company and the
New York office of the RCA"

"In 1926 a commercial radio link for facsimile working was opened
between the London office of the Marconi Wireless and Telegraph
Company, and the New York office of the RCA"
http://www.hffax.de/history/index.html

The first facsimile was transmitted from London to Paris in 1907:
"1907 - International fax 
It took 12 minutes to transmit a picture of King Edward VII over the
London to Paris telephone circuit using early facsimile equipment"

"Facsimile telegraphy was introduced in the nineteen twenties.
Photographs were scanned by a photocell and copied onto photosensitive
paper by means of a controlled light source at the receiving end. In
1927, the Berlin-Vienna route went into operation using the
Siemens-Karolus-Telefunken system. This new way of transmitting
photographs was used in particular by the press":

Thank you fp for leads to a partial answer. Looking forward to details
about the translantic transmission.
Regards and a good start to the year.

And all the best for 2005, can1972.

The June 1924 transatlantic transmission went to Sweden:
"On June 5, 1924, the first wireless telegraph picture was transmitted
across the Atlantic. This was a handwritten page from a letter from
Ernst Alexanderson to his father Professor Alexanderson, in Sweden"

"Alexanderson transmitted the first facsimile message across the
Atlantic on June 5, 1924"

"R. Ranger at RCA achieves the first transmission of a photograph from
the US to Britain. His method involves placing a print on a cylinder
that rotates while being scanned by a light beam"
http://people.deas.harvard.edu/~jones/cscie129/nu_lectures/lecture8/graphic%20telegraphs/graphic_tel.html

More on Richard H. Ranger (1889-1962):
"As a designer for the Radio Corporation of America (RCA), in 1924,
Richard Ranger invented the wireless photoradiogram, or transoceanic
radio facsimile, the forerunner of today?s "Fax" machines. A
photograph of President Calvin Coolidge sent from New York to London
in November 1924 became the first photo picture reproduced by
transoceanic radio facsimile"

Thank you fp.
I now know that the first transmissions were in the 20s. 
I know that a photo was transmitted by the founders of Cable and
Wireless over the Atlantic and that was a first, but thought it was
some  time in the 40s.
I consider my question answered but dont see the option to declare it answered.
Thanks for letting me know how, if I am the one to do so.
Regards,
Can
