in the twentieth century and remains in common use in the early twenty-first. In fact, the global communications network of the twenty-first century has its roots in the Victorian era. Photography was realised in 1839 by Louis Daguerre in France and William Fox Talbot in Britain. By 1889, hand-held cameras were available. Another important innovation in communications was the Penny Black, the first postage stamp, which standardised postage to a flat price regardless of distance sent. Railways A central development during the Victorian era was the rise of rail transport. The new railways all allowed goods, raw materials, and people to be moved about, rapidly facilitating trade and industry. The financing of railways became an important specialty of London's financiers. They retained an ownership share even while turning over management to locals; that ownership was largely liquidated in 1914–1916 to pay for the World War. Railroads originated in England because industrialists had already discovered the need for inexpensive transportation to haul coal for the new steam engines, to supply parts to specialized factories, and to take products to market. The existing system of canals was inexpensive but was too slow and too limited in geography. The railway system led to a reorganisation of society more generally, with "railway time" being the standard by which clocks were set throughout Britain; the complex railway system setting the standard for technological advances and efficiency. The engineers and businessmen needed to create and finance a railway system were available; they knew how to invent, to build, and to finance a large complex system. The first quarter of the 19th century involved numerous experiments with locomotives and rail technology. By 1825 railways were commercially feasible, as demonstrated by George Stephenson (1791–1848) when he built the Stockton and Darlington. On his first run, his locomotive pulled 38 freight and passenger cars at speeds as high as 12 miles per hour. Stephenson went on to design many more railways and is best known for standardizing designs, such as the "standard gauge" of rail spacing, at 4 feet 8 inches. Thomas Brassey (1805–70) was even more prominent, operating construction crews that at one point in the 1840s totalled 75,000 men throughout Europe, the British Empire, and Latin America. Brassey took thousands of British engineers and mechanics across the globe to build new lines. They invented and improved thousands of mechanical devices, and developed the science of civil engineering
