Abstract
May 6, 1845.—The introduction of the electric telegraph and its rapid progress were mainly due to the united efforts of Sir Charles Wheatstone and Sir William Fothergill Cooke, who, approaching the subject one from the scientific and the other from the business point of view, were brought together at a time when many attempts were being made to devise a practical system. Their first patent was taken but in 1837. But complete success was not achieved until they produced the single needle telegraph, which was patented by them on May 6, 1845. A special Act of Parliament was passed to permit the formation of a company of more than twelve persons (the maximum number allowed under the various grants) to work this and all the earlier patents of the two inventors.
