Thanks to Allan Green for providing the scan of this photograph.

From Telcon House Magazine No. 5:

The above photograph shows the Submarine Cable Electrical Test Engineers at Greenwich in 1895 [but note that the photograph is dated 1890 by hand], with the exception of Messrs. Clark (Chief Electrician), Todhunter and Wittrick, who were doubtless at sea, and also possibly of Messrs. Clifford and Riddle. Our correspondent is unable to say definitely whether the two last named were in this department or not.

In those days the duties of the Electrical Test Staff covered a wider field than they do now. The Company then ran its own steam-driven generators and, in addition to cable testing, these men were responsible for electric lighting and power, electric welding, and the telephone system. These latter duties are now undertaken by the separate Electricians' Department.

Many of the instruments then used were extremely delicate, and Dr. Weatherall had a great reputation for his skill in repairing not only these, but also all the sundry watches which had ceased to function properly. Rather an autocrat in his own sphere of work, he would brook interference from nobody.

Mr. Tonking was known as the inventor of the Tonking test key which is still in use to-day. Mr. Stevenson's stately progress through the factory on his daily tour of inspection was the signal for the youngsters (one of them our Mr. F. Foster) to scuttle away like rabbits and get very busy. Incidentally, Mr. Foster remembers that one of his duties was to run up the road every morning with a large medicine bottle and buy twopenny worth of gin for one of these gentlemen who shall remain unnamed.

The building seen in the photograph was known as the Oil Store and still exists near the Tape Slitting Shop and Enderby House. The old type cable buoys are also of interest.

When the photograph was published in the Telcon House Magazine No. 5 in 1949 it generated a number of comments from old-timer readers, and another photograph from the same period was printed in the next issue (No. 6) with this letter:

DEAR SIR,—I see you show in your last Magazine a reprint of the photo of the Electrical Staff at Greenwich in 1895, and are in doubt regarding certain members not in this group.

I enclose a photograph which, I believe, was taken at the same time, and which will account, I think, for some of the missing members you refer to.

As far as my memory helps me (reading l. to r.) No. 2 is Mr. Clifford, No. 3 Mr. Riddle ?, No. 6 Mr. Todhunter ?, No. 7 Mr. R. London, and No. 8 Mr. Churchill.

You are at liberty to retain both these originals if only for your museum.—Yours faithfully, CHARLES MAY, 17, Cedarhurst Drive, Eltham, London, S.E.9.

[The above letter was addressed to Mr. Lawford. As far as we have been able to ascertain from the older employees still with us, and with the aid of the names supplied by Mr. May, the complete list is as follows (l. to r.): Messrs. Lucas, Clifford, Riddle, Sherwin, Corder, Todhunter, London, Churchill.—ED.]

Frank R. Lucas, Henry Clifford, Chas. Crook,
Sherwin, Corder, Todhunter, London, Churchill

In the same issue there was also this letter from Marian Clifford, Henry Clifford’s daughter-in-law:

DEAR SIR.—My husband, Alexander Clifford, has asked me to write and tell you how very much he appreciates the Magazine.

He is especially interested in this last, No. 5, which mentions his father, Mr. Henry Clifford, and he wishes me to tell you Mr. Clifford was never an Electrical Test Engineer. He was Chief Engineer and designed all the paying-out gear for both the 1858 and 1866 Atlantic Cables which is, I believe, the same in principle as that used to-day; he also introduced the brass tape serving for cables as a protection against the teredos. Later, Mr. Henry Clifford was Managing Director, and was followed by Mr. Frank R. Lucas.

On page 12 you show a photograph of the working model of the ‘Great Eastern’ which we presented to the Telegraph Construction and Maintenance Co., Ltd., in 1927, and which was made at the works for Mr. Henry Clifford many years before. If we can be of any help to you in verifying dates, etc., from Mr. Clifford’s diaries, we shall be only too pleased. Yours Sincerely, MARIAN G. CLIFFORD, Carriers, Lindfield, Sussex.

Alexander Clifford had also worked at Telcon, from April 1893 until his retirement on 31 December 1927.

Here is the photograph and story of Henry Clifford’s model of Great Eastern from Telcon House Magazine No. 5 (1949).


This ship, which figures so prominently in the early history of submarine cable laying, held the record as the world’s largest ship for close on forty years, and her dimensions were not exceeded until about ten years after she was broken up.

It was I. K. Brunel (seen in the old photograph reproduced on p. 16 of Telcon House Magazine, No. 3) who designed the ship and supervised its construction at Millwall. Unfortunately he lived only just long enough to witness her trials.

In these works we have an excellent working model, roughly five feet long (the actual ship was 692 feet long) of the “Great Eastern” as the above photograph shows. The paddles are driven by steam and the screw by a small clockwork motor which runs for five minutes. The model, which is some 60 years old, was sent to the Chicago International Exposition held in the early 1930’s and returned only after the outbreak of the second world war. During the war it was seriously damaged by bomb blast, but it has been carefully reconditioned and once again looks as good as when first constructed.

Oddly, the model has five funnels, even though one funnel had been removed in 1865 when Great Eastern was fitted out by Telcon for cable laying. Henry Clifford, who was also a skilled artist, had painted the ship in this configuration many times, so it is hard to understand this error in the model.

Another photograph of the model appeared in Telcon House Magazine No. 22 (1953) as part of a feature on James Dugan’s just-published book, “The Great Iron Ship.”

Henry Clifford’s Great Eastern model has been missing for many years, and its present location is unknown.
