19.1 Urbanization and its challenges  (Page 2/10)

The keys to successful urbanization

As the country grew, certain elements led some towns to morph into large urban centers, while others did not. The following four innovations proved critical in shaping urbanization at the turn of the century: electric lighting, communication improvements, intracity transportation, and the rise of skyscrapers. As people migrated for the new jobs, they often struggled with the absence of basic urban infrastructures, such as better transportation, adequate housing, means of communication, and efficient sources of light and energy. Even the basic necessities, such as fresh water and proper sanitation—often taken for granted in the countryside—presented a greater challenge in urban life.

Electric lighting

Thomas Edison patented the incandescent light bulb in 1879. This development quickly became common in homes as well as factories, transforming how even lower- and middle-class Americans lived. Although slow to arrive in rural areas of the country, electric power became readily available in cities when the first commercial power plants began to open in 1882. When Nikola Tesla subsequently developed the AC (alternating current) system for the Westinghouse Electric&Manufacturing Company, power supplies for lights and other factory equipment could extend for miles from the power source. AC power transformed the use of electricity, allowing urban centers to physically cover greater areas. In the factories, electric lights permitted operations to run twenty-four hours a day, seven days a week. This increase in production required additional workers, and this demand brought more people to cities.

Gradually, cities began to illuminate the streets with electric lamps to allow the city to remain alight throughout the night. No longer did the pace of life and economic activity slow substantially at sunset, the way it had in smaller towns. The cities, following the factories that drew people there, stayed open all the time.

Communications improvements

The telephone, patented in 1876, greatly transformed communication both regionally and nationally. The telephone rapidly supplanted the telegraph as the preferred form of communication; by 1900, over 1.5 million telephones were in use around the nation, whether as private lines in the homes of some middle- and upper-class Americans, or jointly used “party lines” in many rural areas. By allowing instant communication over larger distances at any given time, growing telephone networks made urban sprawl possible.

In the same way that electric lights spurred greater factory production and economic growth, the telephone increased business through the more rapid pace of demand. Now, orders could come constantly via telephone, rather than via mail-order. More orders generated greater production, which in turn required still more workers. This demand for additional labor played a key role in urban growth, as expanding companies sought workers to handle the increasing consumer demand for their products.
