First World War Centenary Commemorations 2014 - 2018

Over the coming four years there will be a focus on the use of wireless by all three armed services during the conflict, together with references to related activities both locally in Essex and nationally.

During WWI, the British Navy was faced with the possibility of action in any of seven seas and set about creating its own world communication network for its scattered fleets. Marconi's Wireless Telegraph Company was contracted to build a dozen stations on widely separated and sometimes isolated sites.

The development of mobile wireless sets was a crucial part of the war effort. As early as 1902 the British War Office had an interest in military portable stations and official tests were undertaken. This resulted in transportable wireless stations being used during British Army manoeuvres in 1903. These sets used demountable umbrella-type antennae, syntonic tuned transmitters and reception by magnetic detectors.

The early army wireless installations were carried by horse-drawn wagons. Later Marconi looked at developing transportable sets housed in self-propelled vehicle, in particular installed in a Star motor car:

As part of this initiative we have become a member of the First World War Centenary Partnership being coordinated by the Imperial War Museum – our entry can be seen here and another Chelmsford entry here.

As a general introduction, and to show the extensive involvement by Marconi, a series of documents which outline the supply of equipment, the drafting of personnel and the design and production in laboratories and factories is mounted here:

Official Government Statement.

'Owing to the present urgent demand for Wireless Operators in the Mercantile Marine, students entering the school prior to their eighteenth birthdays, and making such progress that they are able to obtain the necessary certificates on or before reaching the age of 181/4, will be temporarily exempted from military service until a sufficient number of Operators has been obtained. This exemption continues so long as students of military age who have passed into the Mercantile Marine are employed as Operators at sea.'

Free Training. Good Pay. Permanent Positions.

The involvement of Marconi radio officers was vital to the conduct of the war - this is an extract from the book by H.E. Handcock, Wireless at Sea: the First Fifty Years (Chelmsford, 1950)

Immediately on the outbreak of war the Admiralty took steps to secure the services of Marconi operators for all branches of the service. In answer to the Government’s call there came an army of lads and young men from all classes who had gone from school to the Marconi Marine Company, in whose offices they had trained in Morse and the operation and maintenance of wireless apparatus. These at once volunteered their services to the Admiralty and the War Office, their places being taken by other lads clamouring to be trained as wireless operators. In due course the Company provided not merely an army of operators (3300 men were trained during the war), but also technical experts whose knowledge was unrivalled and whose service to the country many tributes were made.

The Company kept its offices open day and night for the purpose of examining lads who came from all parts of the country to offer themselves as operators. So great was the demand, that some of the pupils and enrolled scholars were as young as sixteen years. The staff at Marconi House worked to the limits of their power and to the last ounce of their energy to meet the great emergency. Every ship that arrived at a British port with a wireless operator on board brought a volunteer to the Admiralty. These men were taken in their hundreds from the Merchant Navy and distributed as quickly as possible among ships of war of all types from the battleship to the armed trawler.

But although the Navy’s problem was being solved another was being created in the Merchant Fleet. Not only were the big liners deprived of their Marconi operators but ships which hitherto had not been fitted with wireless (vessels of 1600 to 3000 tons) found that wireless was a necessity. In addition, whereas before the war it was sufficient for one operator to be carried, now it was essential that there should be at least two operators to keep a continual vigil.

A conference was held at the Admiralty for the purpose of considering the practicability of fitting all ships of 1600 tons and over with wireless telegraphy. The desirability of carrying two operators for maintaining continuous watch was also emphasised, the authorities thereupon approached the Marconi Company with the view of ascertaining whether they could possibly cope with so huge a task. Few ships under 3000 tons had up to date been fitted, and it was quite evident that not only would a tremendously increased volume of wireless apparatus have to be made and supplied, but that the operating staff would need to be practically trebled. It was estimated, in other words, that the trained personnel, already increased in three years from 1000 to nearly 3000 men, would have to be expanded to a total of about 4000 to 4500 in a few months. With the full knowledge of this gigantic task, Mr. Godfrey Isaacs, on behalf of the Company, undertook definitely to provide both apparatus and men.

Arrangements were made for a course of free tuition, and the accommodation of Marconi House being filled to overflowing, arrangements were made with King’s College and Birbeck Institute for the reception of additional volunteers. Similar schemes were set afoot in several provincial centres. At the same time, pressure of a severe nature was put upon the Marconi Works at Chelmsford. The delicate mechanism employed in wireless telegraphy, with the Company’s research and development and the constant improvements being introduced by experts at headquarters, had to be manufactured at speed and in such quantity as never before had been contemplated. And, in addition, there was a constant demand for those simpler instruments – keys, buzzers, telephones, etc, which are necessary for the instruction of pupils. The manner in which this problem was handled is beyond praise.”
