Highly important to industrial progress are the inventions that lead to greater productivity in the workplace and a larger variety of mass-produced goods in the home. The first basic change in the speed of communications was the invention of a workable telegraph by Samuel F.B. Morse. It was first successfully demonstrated in 1844. By the time of the Civil War, electronic communication by telegraph and rapid transportation by railroad already were becoming standard parts of modern living, especially in the northern states. After the war, Cyrus W. Field’s invention of an improved transatlantic cable in 1866 made it possible to send messages across the seas in that very moment. Now cables link all continents of the world in an electronic network of instantaneous, global communication. Another huge step in communications technology is the invention of the telephone by Alexander Graham Bell in 1876. Topping the list of hundreds of noteworthy inventions are the typewriter in 1867, the cash register in 1879, the calculating machine in 1887, and the adding machine in 1888. Some products for the consumer that were in widespread use were George Eastman’s Kodak camera in1888, Lewis E. Waterman’s fountain pen in 1884, and King Gillette’s safety razor and blade in 1895.
