The WCSIM promotes the craft of scientific instrument making and the exchange of ideas and information by members and guests through meetings, visits, lectures and social events.

The members are all linked with the manufacture or use of scientific instruments. The Company advances the craft through traditional apprenticeships supervised by Liverymen, and through its educational trust fund. The fund provides grants, bursaries and scholarships at A level, undergraduate and post graduate and research fellow levels.


Formation of the livery

The Guild was formed in October 1955 by members of the Industry and with the support of the Clockmakers and the Spectacle Makers Companies, to foster scientific instrument making and to promote goodwill in the science and craft of measurement and instrumentation. One of the founder firms at that time was known to date back to 1640. Grant of Arms was achieved in 1956 and the Letters Patent as a Livery Company of City of London were granted in 1963.

The Charitable and Educational Trust

One of the primary objectives of the Company is to encourage young people to particpate in the craft through gratns, prizes, scholarships and apprenticehsips. The Company has relationships with a number of universities as well as the armed forces, the Young Engineers program and the Arkwright Scholarship Scheme. The Trust has been built up over the years through regular donations from Liverymen, endowments and investment gains. The Trust operates under a Trust Deed and has a group of managing trustees including the Master, who chairs the Trust, the Deputy Master, the Honorary Treasurer and two Past Masters. The Charity also provides some limited financial support to Liverymen and Freemen who have fallen on hard times.
