**SCIENTIFIC INSTRUMENT SOCIETY Report to the Charity Commission** 

## **2024** 

## **1. INTRODUCTION** 

## **OBJECTS** 

In the interest of the public benefit and education, the objects of the Society are the promotion and advancement of the knowledge of the history of scientific artifacts and their preservation. 

## **POLICIES** 

The main policy of the Society is to provide the infrastructure to gain its objectives and in approved cases to provide financial assistance by which its members and others may benefit in some aspect of their activities whilst helping to achieve the objects of the Society. 

To achieve this overall policy, the Society maintains a worldwide membership, issues the Bulletin of the Scientific Instrument Society, holds regular meetings and conferences, and contributes where appropriate to debate on issues concerning the objects of the Society. In terms of direct financial benefits, membership for students is subsidised and grants are made to individuals for research work related to the Society's aims. 

## **GOVERNANCE** 

The society was formed in 1983 and is a registered UK charity, number 326733. It is regulated by a written constitution last amended in 2024 (8.2 tenure reworded: ‘Officers listed in paragraph 8.1a shall retire annually at the AGM but shall be eligible for re-election.  Should a member be standing for election to the office of Chairman, Vice-Chairman or Secretary for more than 5 years in succession, this term extension must be approved by the Membership at the AGM’. The appointment and induction of new trustees is carried out as appropriate to the needs and best interests of the society. 

## **ORGANISATION** 

The controlling body of the Society is its Committee in which several members hold designated posts (e.g. Treasurer) and which includes up to seven ordinary members of the Society. Elected Members of the Committee are the Trustees of the Society during their terms of office. (The Committee may co-opt other members of the society but these co-opted members are not Trustees of the Charity.) There is an Executive Officer responsible for the day-to-day administration of the Society; this post is provided under contractual terms and is reviewed annually. No member of the Committee receives any remuneration for services to the Society but expenses may be paid in approved instances. 

## **ACCOUNTING** 

The Society is not obliged to have a full audit of the accounts, and therefore the Committee has chosen to have the accounts examined. For this year the examination was carried out by Hunter & Co. Chartered Accountants.

## **ANNUAL GENERAL MEETING** 

Page 1 of 4 

Charity Report 2024 



The 40[th] Annual General Meeting was held on Monday 15[th] July 2024 at 6pm at The British Optical Association Museum, 42 Craven Street, London WC2N 5NG and via Zoom. 

The following elections were made: 

**Officers** Chairman Neil Handley Vice Chairman David Howarth Treasurer David Howarth Editor Willem Hackmann Secretary Alison Boyle Meetings Secretary Vacant 

## **Ordinary Committee Members** 

Nicolás de Hilster (Website); Michael Stewart (Advertising and Marketing); Alex Rose (Grants) 

## **OTHER MEETINGS** 

On 9[th] and 10[th] March 2024, the Society was able to complete our long-held ambition of visiting Armagh Observatory and Planetarium, in Northern Ireland. Postponed numerous times by the pandemic, we finally made it and thoroughly enjoyed our exploration of the site and collections, courtesy of Professor Michael Burton and his team. Carol Conlin at Armagh Robinson Library also made us very welcome with an excellent visit to the historic collections on the Sunday morning. 

The Annual Summer Study Tour took place in mid-May to Istanbul, assisted by a local member host, Dr. Taha Arslan, Professor at Istanbul Medeniyet University, along with the support of his students, Beyza Topçuoğlu and Afra Akyol.  Members enjoyed a fabulous programme with visits to numerous venues, including the Rahmi Koç Museum, Museum of the History of Science and Technology in Islam, Kandilli Observatory (astronomy, seismology and meteorology) and a beautiful exhibition at the Pera Museum on the history of weights and measures. Having the opportunity to make a behind-the-scenes visit to Taha’s astrolabe workshop was a real highlight! There were 16 delegates from the UK, USA, Denmark, Italy and the Netherlands. 

The Society’s AGM took place on Monday 15[th] July at at 12.30pm at The British Optical Association Museum, 42 Craven Street, London WC2N 5NG and via Zoom.  It was attended by 27 people (19 on Zoom) 

The Society continued with the monthly online lecture series for our members ‘Fireside Chats’, which proved to be a great way to stay connected with our international members.  Eight talks took place with approximately 20-40 members attending each event.  Our speakers spoke on a range of topics including Irish scientific instruments, the Bakken collection, College Heights Weather Station, the mythology of Marconi’s cigar box, and, in a very timely manner, the Greek School teaching collections located in Istanbul, which some of us were able to visit in person. 

On Friday 8th November the Society’s 12[th] Gerard Turner Memorial Lecture in honour of the Society’s first President and founding Chairman took place at the History of Science Museum, Oxford, followed by a dinner locally. This attracted an audience of 47 people to hear guest speaker Dr Stephen Johnston, Curator Emeritus talk on ‘Back to the Future: New Approaches to the Astrolabe’.  Prior to the lecture there was an opportunity for members to visit a new exhibition at Oxford’s Centre for Islamic Studies: Lines of Faith: Astronomy and the Art of the Astrolabe in the Islamic World, with a curator led tour by Stephen Johnston. 

## **MEMBERSHIP** 

The annual membership subscriptions for the year 2024 were increased by 10% in order to keep pace with inflation: 

Residence in UK £69.00 (Family £79.00) Residence in Europe £88.00 (Family £94.00 Residence in Rest of World £94.00/$136 (Family £100.00/$145) Student rate £25.00 in UK & £40.00/$58 elsewhere 

Page 2 of 4 

Charity Report 2024 



There were 360 members as at 31 December 2024, a small decrease on last year. 

## **THE SIS BULLETIN** 

Four issues of the Bulletin were published on time during the year. This continues to be the Society’s main vehicle for achieving its objectives. 

## **THE WEBSITE** 

The website continued to be developed as an increasingly important vehicle of communication. 

## **RESEARCH GRANTS** 

The Society has agreed as a means of furthering its objectives to award a number of grants to assist research in its field of study on a regular basis. Details were published in the Bulletin, on the website and by direct communications to academic departments. 6 applications were received and 4 awards were made for the 2024 awards. Grants are paid when applicants have carried out the relevant work but are accrued to our accounts at the time the application is approved.  2 were paid this year. 

## **SUPPORT FOR PUBLICATIONS** 

The Society has a policy of making advance purchases, on behalf of members, of important reference works which can secure the publication of specialised works. In 2024 no purchases were made. 

## **3. FINANCIAL RESERVES** 

The Society has no income from investments as such but has sums deposited in an interest-bearing savings account. This capital acts as a source for charitable activities and a reserve against uncertainties. The Society is not active in 'fund-raising' but receives small donations from time to time. Conferences are essentially self-supporting and any surplus is directed to furthering the Society’s objectives. 

The Society supports student membership at reduced rates and seeks to promote specific items to achieve its aims rather than the general distribution of its charitable assets. Thus sums are made available from time to time for research, publications, etc., all requiring such sums to be available when required. 

The reserves policy may therefore be stated as the maintenance of sums on deposit to provide a source for major charitable activities and a reserve against uncertainties, any income from which is directed towards the running costs of the Society. 

Figures given for levels of reserves relate only to that money which is currently available for use by the trustees.  As at 31 December 2024 the Society's net unrestricted funds amounted to £29,096. 

## **4. RISK ASSESSMENT** 

A full risk assessment was carried out during 2008. The Committee reviews this on an annual basis and is once again able to confirm that the few risks to which the charity is exposed have been identified and suitable precautions are in existence. 

## **5. ADMINISTRATION** 

The Committee met on five occasions during the year. 

Our Executive Officer for the past 7 years has been Mrs. Sarah Cavalier. All enquiries should be addressed to: The Scientific Instrument Society, The Old School House, School Lane, Stadhampton, Oxfordshire, OX44 7TR E-mail info@scientificinstrumentsociety.org

Charity Report 2024 



The Society has a website at www.scientificinstrumentsociety.org 

## **6. FULFILLMENT OF CHARITABLE OBJECTIVES** 

As detailed above the Society continues to fulfill its objectives by publishing its learned journal on time four times a year; by holding lectures on appropriate topics which are open to the public and in the case of the Annual Lecture without charge; by arranging and organising study tours, by supporting the publication of educational books in its field of interest and by the award of research grants. 

## **7. DUTY OF TRUSTEES** 

The Trustees confirm that they have complied with the duty in section 17(5) of the Charities Act 2011 to have due regard to the guidance published by the Charity Commission. 

## **8. ADOPTION** 

This Report was adopted unanimously by the Committee in its meeting on Monday 15[th] July 2024
