Summary
| Description | Sir William Thomson, Lord Kelvin, (1824-1907) was Professor of Natural Philosophy at Glasgow University, and was well known for his work in many branches of physics, including electricity. The first transatlantic telegraph cable was laid in 1858, reducing the time it took for messages to cross from days or months to hours. The success of the system relied on an instrument that could detect the tiny electrical signals that had passed so far under the sea. Thomson's galvanometer was the only instrument sensitive enough to detect reliably the first transatlantic telegraph messages. Made by J White. |
