June 25, 1879. Sir William Fothergill Cooke died.—While a student of anatomy and physiology at Heidelberg, Cooke in 1836 had his attention directed to the electric telegraph, and in 1837, on his return to England, he became a partner with Wheatstone. Joint patents were taken out in 1837 and 1838 for instruments with five and two needles, and in 1845 the single needle instrument was produced. After that the telegraph was speedily adopted on all the railway lines of the country. The first commercial telegraph of Cooke and Wheatstone was erected in 1837 on the London and North Western Railway between Euston and Chalk Farm.
