Administrative history:
Oswald John Silberrad was born in 1878 at Buckhurst Hill in Essex. His family, German in origin, had been resident in England since the 18th century. Despite showing exceptional promise in science at school, Silberrad's inaptitude at classics ensured that the doors of all English universities were closed to him. He studied chemistry at the City and Guilds Technical College, Finsbury, before attending the University of Würzburg, Germany, from 1898 to 1900. Such were his family's straightened financial circumstances that his studies in Germany would not have been possible without the generosity of his uncle, Sir Charles Wyndham. At Würzburg, studying under such professors as A.R. Hantzsch and W.C. Roentgen, Silberrad proved himself to be unusually innovative at experimental work and took his thesis 'Uber die polymerisations producte aus Diazoessigester' in a remarkably short time.
On leaving Würzburg Silberrad worked for a short period at the Davy Faraday Laboratory at the Royal Institution, experimenting on hydrotetrazines and triazoles. He then began to turn his attention to the application of chemical discoveries to industry. His first consulting post was as Research Chemist to W.J. Bush & Co., working principally on essential oils. However, Silberrad's German training, with its emphasis on original practical work, brought him to the notice of the newly-formed Explosives Committee which had been set up to investigate the shortcomings of British munitions exposed during the Second Boer War. In December 1901, at the age of twenty-three, he was appointed Chemist to the Explosives Committee and, shortly afterwards, head of the Committee's research establishment at the Royal Arsenal, Woolwich.
Silberrad immediately commenced research on the most urgent problem identified by the Committee in the aftermath of the Boer War: the lamentable failure of high explosive shells filled with lyddite to detonate properly. He devised a means of detonating lyddite using trinitrophenylmethylnitramine (or 'tetryl'), known as 'Silberrad's explosive' when it was introduced into the British Service in 1903. He then found that Trinitrotoluene, or 'TNT', could also be used as a detonator and possessed certain advantages over tetryl. In addition to these important discoveries, he succeeded in producing a 'flashless' powder for certain types of artillery. Through Silberrad's energy and organisational ability a new Research Department at Woolwich was formed and he become its Director and Superintendent. However, in his efforts to eliminate inefficiency in the department, he was frustrated by continual obstruction and meddling by officials at the War Office which led to his acrimonious departure from Woolwich in 1906. He later cited the reasons for the attitude of the officials towards him as being his extreme youth and his 'contempt for inefficiency'.
In 1907 Silberrad founded the Silberrad Research Laboratories at Buckhurst Hill (later moving to Loughton) and for the rest of his career worked as a consulting chemist. In 1908 he solved the problem of the erosion of warships' bronze propellers, which had baffled all previous investigations, by developing a new bronze alloy which withstood erosion. His research on dynamites before the outbreak of World War I resulted in the development of a new range of powerful explosives based on ammonium perchlorate. In order to exploit these products commercially, Silberrad helped to set up and manage a dynamite-manufacturing company in north Wales, Ergite Ltd.
From 1915 until the end of World War I Silberrad served as Honorary Consultant to Lord Moulton, Director-General of Explosives Supply, despite suffering serious injuries in an explosion in June 1915 at the Ergite factory which had started to manufacture TNT for the war effort. He himself performed an invaluable service to the country by improving the method for manufacturing lyddite which was desperately needed to supplement the inadequate supplies of TNT to the front. Silberrad also produced a 'flashless' artillery powder (no steps had been taken by the War Office to develop his initial research on 'flashless' powders carried out at Woolwich) which he demonstrated to be effective in most guns. The War Office, however, raised a series of objections to the new powder and it was not used during the war. The problem of what to do with large quantities of dangerous TNT residues was also referred to Silberrad who found that they could be converted into valuable dyestuffs.
Other significant research carried out by Silberrad before World War I produced an erosion-resisting gunsteel and an improved method for the retting of flax. After 1918 he continued to devise and patent new processes which made an impact in a number of industrial sectors. Among his discoveries were a new agent for chlorinating organic compounds and a new method of shooting oil wells. Being interested in the commercial possibilities of chemical discoveries, he held a number of company directorships and took part in some business ventures.
Despite having the strong backing of a number of distinguished scientists, including Sir Phillip Watts and Sir William Crookes, Silberrad's candidature for Fellowship of the Royal Society met with failure in 1921. He never received any official recognition for the discoveries he made while in the service of the government in 1901-1906 and 1915-1918.
Silberrad took a keen interest in social and economic matters and believed that high taxes sapped the nation's industrial strength. He died on 17 June 1960.

The material in the collection covers the period ca 1891-1965 and is presented in five sections.
Section A, Biographical, covers the period ca 1891-1960. There are lecture notebooks from Silberrad's years at Finsbury Technical College, a childhood natural history notebook with sketches, and diaries dating from 1912 to 1926. Of especial interest are drafts of an unpublished biography of Silberrad by his sister Dora and of a revised version by the Hon. Hugh Fletcher Moulton. Included in the book are quotes from memoirs written by Silberrad; some are particularly valuable for the light they shed on his work at the Research Department, Woolwich, and his relations with the War Office. A group of correspondence with prominent scientists, 1918-1921, relates to his unsuccessful candidature for Fellowship of the Royal Society. A series of career files, mostly of miscellaneous material, includes testimonials written by college and university tutors and superiors in organisations in which he was employed. There is also a draft of a book (apparently unpublished) of fairy tales for children written by Silberrad and his sister Phyllis.
Section B, Research and consultancy, is extensive and covers the period 1898-1959. It provides significant documentation of much of Silberrad's wide-ranging consultancy work for industry and the government, his patenting of discoveries and business interests. Little material, however, survives from his years at the Research Department, Woolwich. Large groups of correspondence and papers relate to his research on the erosion of ships' propellers and his innovative work on explosives during the period 1911 to 1918 which included the development of ammonium perchlorate dynamites, the 'Hotchkiss-Silberrad Fuse' and a 'flashless' artillery powder. Among the correspondents during the years 1915 to 1918 are Lord Moulton, the War Office and other government departments. Silberrad's involvement in Ergite Ltd is well documented among the papers relating to dynamites. Other topics covered in this section include the manufacture of dyestuffs and cellulose acetate and research on an erosion-resisting gunsteel. There is a series of forty notebooks, 1904-ca 1951, containing details of various experimental work with analysis. A few earlier lecture notebooks date from his years as a student at the University of Würzburg. Other papers document legal cases arising from a few of Silberrad's consulting posts and some in which he appeared as an expert witness. There are also more than one hundred photographic prints, the greater part showing experiments with the 'flashless' artillery powder he developed between 1915 and 1917. Others show laboratories and buildings at Woolwich, 1901-1906. Silberrad's own laboratories in their early development, and the results obtained by blasting with his new dynamites.
Section C, Publications, patents and lectures, is slight. The publications material includes Silberrad's printed treatise on the stability of nitro-cellulose, 1904, and a draft of an article on artificial rubber which appeared in a German publication. Sets of original patents obtained by Silberrad in Great Britain and overseas cover the period 1910 to 1942. There are drafts of three lectures by him of which one can probably be dated to 1902-1906. No significant details concerning the relevant venues or occasions for these exist.
Section D, Financial papers, comprises income tax papers, account books and receipts etc, dating from 1905 to the years immediately after his death in 1960. The material relates to both Silberrad's private financial affairs and the business of the Silberrad Research Laboratories.
Section E, Correspondence, is extensive, and illustrates the diversity of Silberrad's research, consulting and business interests. The main series, 1905-1951, is arranged alphabetically by correspondent within each year. The correspondents are chiefly scientists, including Sir Phillip Watts, Sir William Crookes, Cecil Desch and Sir Andrew Noble, family members, principally his brothers Charles and Harold, companies for which he worked, patent agents, solicitors and suppliers. There is also a small group of miscellaneous correspondence, 1922-1926, n.d., which was separated from the above sequence.

Administrative history:
The material relates to the biography of Silberrad 'From Corrugated Iron Shed to Armament Research Establishment'.
The biography is a record of Silberrad's career by his sister Dora M. Silberrad who died in 1927. The Hon. Hugh Fletcher Moulton, son of Lord Moulton, former Director-General of Explosives, later revised her draft, with Silberrad's assistance, and it was given the above title. Correspondence between Moulton and Silberrad indicates that the work was intended for publication, though no details regarding eventual publication have been found.

SECTION B RESEARCH AND CONSULTANCY  NCUACS94.7.00/B.1-B.3578  [n.d.]


Related information: For letters and papers, including drafts of a biography of Silberrad, which date from, or cover, his period as Director of Research at Woolwich, 1901 to 1906, see Section A. For further scientific correspondence and material relating to Silberrad's career see Sections A and E.

Contents:
The papers in this section provide extensive coverage of Silberrad's diverse research and consultancy work and business interests from 1907, the year he founded the Silberrad Research Laboratories. Apart from notebooks in the first sub-section, little material earlier than 1907 survives. Part of the material was originally found organised in a filing system, the 'systematiser'. This arrangement appeared to be alphabetical by topic or organisation, though was considerably disarranged. In order to highlight Silberrad's important work on the erosion of ships' propellers and explosives between 1907 and 1918, the relevant groups of papers have been treated as distinct sub-sections (see the list below). The sub-section 'Explosives' comprises papers relating to three further research topics: Dynamites and high explosives, Fuses and 'Flashless' artillery powder. The remainder of the research and consultancy papers are organised in an alphabetical sequence under the sub-section 'Other topics'. Papers relating to legal cases, in which Silberrad was a plaintiff or appeared as an expert witness, have also been organised into a sub-section to give coherence to this significant development from his consulting work.
The papers are presented as follows:

EROSION OF SHIPS' PROPELLERS  NCUACS94.7.00/B.47-B.376  1908-1932, 1955, n.d

Administrative history:
The erosion of bronze propellers of high-speed ships, a problem which had defeated numerous investigations, was referred to Silberrad in June 1908 by the Director of Naval Construction, Sir Phillip Watts. Silberrad worked closely with the Manganese Bronze and Brass Co. Ltd, which financed the research, and by September 1909 he had discovered a new alloy for propellers that could withstand erosion. The alloy was adopted for Royal Navy vessels before and during World War One and made a significant contribution to the Navy's performance.

Dynamites and high explosives  NCUACS94.7.00/B.377-B.1176  1903-1921, n.d

Administrative history:
In the years immediately before the outbreak of World War One Silberrad developed and patented powerful new dynamites based on Ammonium Perchlorate and in 1912 helped set up a company in north Wales, Ergite Ltd to manufacture the explosives for commercial use. As Managing Director, he informed the War Department of the effectiveness of his 'Shattergite' explosive for demolition work but the Department was slow to recognise its potential.
In June 1915 a serious explosion occurred at the Ergite works in which Silberrad was injured. Later that month the company was taken over by the Ministry of Munitions to manufacture TNT for use in the World War One. A long dispute over compensation due to the company from the government subsequently arose and the company went into liquidation in 1919 or 1920.

'Flashless' artillery powder  NCUACS94.7.00/B.1228-B.1340  1905-1955, n.d

Administrative history:
During the trench warfare of World War One the British forces were handicapped by their lack of an artillery powder which gave out no flash during firing. When guns were fired at night the flash gave away their positions, enabling the German artillery, which was better supplied with high explosive shells, to destroy them the following day. Following discussions with Lord Moulton, Director-General of Explosives, in the summer of 1915 Silberrad was asked to develop a 'flashless' (or 'flameless') artillery propellant. However, the powder he produced, although demonstrated to be effective, was not acceptable to the War Office on the grounds that the army did not want the complication of having separate powders for day and night firing.
From 1902 to 1906, during his period as Director of Research at the Royal Arsenal, Silberrad had carried out research on this subject, observing the effects of modifying the proportions of the ingredients making up a propellant on the power and heat produced on auto-combustion. At the outbreak of World War Two Silberrad again brought his work on 'flashless' propellants to the attention of the Government which replied that the army already possessed these materials. Silberrad later claimed that the powder he developed during World War One was at least as effective as that used in World War Two.
Most of the material dates from 1915 to 1917, though there are papers relating to his earlier work and to his later interest in the subject.
For photographs of firing trials with Silberrad's powder see NCUACS94.7.00/B.3392-NCUACS94.7.00/B.3497, NCUACS94.7.00/B.3498A. For later papers relating to interest shown by the Hungarian Government in 'flashless' powders see NCUACS94.7.00/B.2930-B.2937.

GENERAL CORRESPONDENCE  NCUACS94.7.00/E.1-E.1221  1905-1951

Contents:
An incomplete series covering many aspects of Silberrad's professional work, and also his domestic and financial affairs. Correspondents include manufacturers, scientists, family members, business associates, patent agents, solicitors and suppliers.
The correspondence was mostly found arranged alphabetically by correspondent or topic (first letter of name only) for a particular year and sometimes chronologically within these groupings. Such arrangements have been preserved, though where a sequence was found in a partly disarranged state an attempt has been made to re-construct the original organisation. In cases where there was much disarrangement letters have been put onto a rough chronological order only within the alphabetical groupings. As related groups of correspondence were originally filed together, correspondence for a particular year often includes a few letters from immediately preceding or following years.
A small amount of correspondence (with German scientists and publishers) is in German.
