Pioneering Work at TINSLEY
Get to know our history
1904 - PRESENT › PIONEERING WORK AT TINSLEY
1904
Sparks of genius
The company was founded by Henry Tinsley in 1904.
In the year that he founded his own firm Henry Tinsley was living in a house called 'Pea Lea' in Elmers Road, Beckenham and started the business from a small workshop at his home where he took on his first employee, William Moat. Equipped with little more than a single lathe Tinsley began making resistance boxes and galvanometers.
This was the origin of the well known Tinsley electronic instrument company.
1905
Pioneering work
Weston Standard Cells - first commercially manufactured in England by H. Tinsley
1907
Snell & Tinsley
Business quickly grew and in 1907 the firm moved to Stanley House, Eldon Park Road, South Norwood where Tinsley entered into a partnership with another instrument maker named Snell - becoming for a short time Snell & Tinsley making telegraph apparatus, condensers, standard cells, potentiometers and 'bridges'. Snell however died after one year of the partnership leaving Henry Tinsley in sole ownership.
1908
Early years
Fortunately during those difficult early years Henry Tinsley would be assisted by his wife Emma, a frugal Quaker who kept a very close eye on finances and helped in many practical tasks, cell making and coil winding.

Rapidly expanding
With the business now rapidly expanding Tinsley was looking for new premises and moved into Werndee Hall in 1916 where the firm would stay for almost 70 years. Werndee Hall consisted of a large house and stable; the building was on a three acre site which was ideally suited to handling the expansion of the business which had occurred due to the first world war when many new and varied instruments were required by the military.
1919
Joined by DC Gall
DC Gall, Henry Tinsleys young cousin joined the firm in 1919 on his release from the Royal Navy Air Service. In charge of the test room manufacturing efficiency was soon improved and piled up orders from home and abroad were soon sorted out and systematically executed. Over the decades which followed a considerable number of instruments made by Tinsley would bear some mark of DC Gall's influence.

Technical Sales
For the first 50 years, unlike the present day Tinsley's did not employ sales engineers apart from the occasions when Henry Tinsleys himself or his nephew visited customers to discuss their requirements. It was in the early 1950's that the firm employed it's first full time technical sales representative; thereafter sales engineers would travel throughout the UK and abroad visiting the company's agents, arranging exhibitions of the firm's products and spreading the com pan's reputation still further.

Calibration Laboratory
In the mid 1960's it was decided to build a separate Calibration Laboratory to undertake all the high precision measurements of the Tinsley instruments and carry out the assembly and adjustments in a temperature and humidity controlled environment.
(ABove: Precision Thermometers being manufactured under clean air conditions).
(Above: A staff gathering, 1964 with a total combined service of over 600 years)
1970
End of an era
DC Gall had reached the age of 77 and feld that he no longer had the energy to continue to run the business and decide to retire. The same year the company was sold to Agricultural Holdings Ltd, which had a large engineering division into which Tinsley became incorporated.
(Above: Mr DC Gall centre, Mr Maurice Gall left and Mr Colin Gall right).
1983
On the move
Despite building extensions, in 1983, given the considerable amount of work which would be required to bring the building up to modern standards, Werndee Hall and surrounding land were sold and the company moved to Imperial Way on the Old Croydon Airport Estate.
1984
The Tinsley Group
Agricultural Holdings Co. Ltd was itself sold to Booker McConnel Ltd, with the exception of Tinsley and one or two other small companies which then became The Tinsley Group Ltd.
1986
A successful partnership
In 1986 the company was introduced to Dr David Henson at that time Senior Lecturer in the Optometry & Visual Sciences Department of Cardiff University and who was looking for a suitable company to help develop his ideas for a new Field Vision Screener. Although outside Tinsley's normal sphere of activities the requirement for high precision electrical measurement was apparent and this became the start os a successful partnership.
1991
Larger premises
The company moved again to a purpose built 25,000 sq. ft factory in King Henry's Drive, New Addington. With the formation of the new group and a younger team managing the business, suitable premises were needed to handle the growth expected with the introduction of new products and business ventures.
2013
Sifam Tinsley Instrumentation
Tinsley acquired by Sifam Tinsley Instrumentation Limited.
2016
The future
Today the Tinsley company has an enormous reputation and whose name is synonymous with quality and reliability. The instruments manufactured today are of an accuracy which was unheard of when Henry Tinsley founded the business but one can be sure he would have proud of the progress that has been made in the century since he founded the company in 1904. His company continues to play a major role in the development of instrumentation and new technology for a whole range of instruments.
