John Pender

Pender was born in the Vale of Leven, Scotland, the son of James Pender and his wife, Marion Mason. He was educated at Glasgow High School. He became a successful merchant in textile fabrics, first in Glasgow, then in Manchester (where he had a warehouse in Peter Street near The Great Northern Warehouse). He lived at Middleton Hall, County Linlithgow, Foots Cray Place, Sidcup, Kent, and Arlington House, 18 Arlington Street London.

In London 1866, Pender was the leading financier/director and Chairman of the Companies involved who, with his colleagues, undertook the first successful laying of the transatlantic cable from Valentia Island off the coast of Ireland to Heart's Content, Newfoundland and Labrador. This cable was the most successful and commercially viable of all the transatlantic cables and was 100% British financed, unlike the previous transatlantic cable-laying attempts, which had had some financial backing from American Investors. The Anglo-American Telegraph Company (formerly the Atlantic Telegraph Company) and The Gutta Percha Company and Glass, Elliott (Greenwich, London) merged into the Telegraph Construction and Maintenance Company 'Telcon' (which was taken over decades later by British Insulated Callender's Cables), and laid the first successful cable in 1866 and ended up manufacturing and laying all of Eastern Telegraph's cables and most of the submarine telegraph cables of the rest of the world.

He founded 32 telegraph companies, including Eastern Telegraph Company, Eastern and South African Telegraph, Western Telegraph Europe and Azores Telegraph Company, Australasia and China Telegraph Company, London Platino-Brazilian Telegraph Company, Pacific and European Telegraph Company which later became Cable & Wireless. In 1934, Imperial and International Communications, formerly the Eastern Telegraph Company (the amalgamation of those 32 telegraph companies), became Cable & Wireless. The new name was designed to more clearly reflect the combined radio and cable services which it offered, without reference to the Empire. Cable & Wireless is one of the world's leading international communications companies. It operates through two standalone business units. International and Europe, Asia & U.S.

Together with City financiers Leopold Salomons and Jabez Balfour, Pender founded the investment underwriting firm the Trustees, Executors and Securities Insurance Corporation, Limited in December 1887.

At the time of his death in Foots Cray Place, Kent, on 7 July 1896, he controlled companies having a capital of 15 million sterling and owning 73,640 nautical miles (136,380 km) of cables (one third of the cables in the world); these cables formed the base of the networks that years later developed into the World Wide Web.

Pender was married twice: firstly in 1840 to Marion Cairns, who died giving birth to his son Henry in 1841 (their eldest son James survived); and in 1851 he married Emma Denison (d.1890). They also had a son John Denison Pender (1855–1929) and two daughters Marion Denison Pender (1856–1955), who married George William Des Voeux, and Anne Denison Pender (1853–1902). The girls were painted in an Aesthetic Movement portrait titled "Leisure Hours" by John Everett Millais in 1864 Detroit Institute of Arts. Pender is buried in the grounds of All Saints' Church, Rectory Lane Foots Cray with a fine but simple Celtic cross memorial, and is also remembered via the inauguration of the Pender Chair from the money raised by the memorial fund at the time of his death.
