Administrative / Biographical History

The Cambridge Scientific Instrument Company was founded in 1878 by two Cambridge graduates, Albert Dew-Smith and Horace Darwin, to meet the need for new types of instrument for laboratory work in Cambridge University, especially instruments for physiology and physics. The company was based initially in Panton Street, before moving to St Tibbs Row in 1882. It became a limited liability company in 1895, following the move to larger premises in Carlyle Road. On taking over the R.W. Paul Instrument Company of Muswell Hill, London, in 1920, the firm became the Cambridge and Paul Instrument Company Ltd. It changed to the Cambridge Instrument Company Ltd in 1924, when it became a public company. In 1968, the firm merged with George Kent Ltd. The merger signalled the end of the company in its original form. It was reorganised into four divisions, and these were eventually sold off separately.
