18.1 Inventors of the age  (Page 2/7)

In offices, worker productivity benefited from the typewriter, invented in 1867, the cash register, invented in 1879, and the adding machine, invented in 1885. These tools made it easier than ever to keep up with the rapid pace of business growth. Inventions also slowly transformed home life. The vacuum cleaner arrived during this era, as well as the flush toilet. These indoor “water closets” improved public health through the reduction in contamination associated with outhouses and their proximity to water supplies and homes. Tin cans and, later, Clarence Birdseye’s experiments with frozen food, eventually changed how women shopped for, and prepared, food for their families, despite initial health concerns over preserved foods. With the advent of more easily prepared food, women gained valuable time in their daily schedules, a step that partially laid the groundwork for the modern women’s movement. Women who had the means to purchase such items could use their time to seek other employment outside of the home, as well as broaden their knowledge through education and reading. Such a transformation did not occur overnight, as these inventions also increased expectations for women to remain tied to the home and their domestic chores; slowly, the culture of domesticity changed.

Perhaps the most important industrial advancement of the era came in the production of steel. Manufacturers and builders preferred steel to iron, due to its increased strength and durability. After the Civil War, two new processes allowed for the creation of furnaces large enough and hot enough to melt the wrought iron needed to produce large quantities of steel at increasingly cheaper prices. The Bessemer process, named for English inventor Henry Bessemer, and the open-hearth process, changed the way the United States produced steel and, in doing so, led the country into a new industrialized age. As the new material became more available, builders eagerly sought it out, a demand that steel mill owners were happy to supply.

In 1860, the country produced thirteen thousand tons of steel. By 1879, American furnaces were producing over one million tons per year; by 1900, this figure had risen to ten million. Just ten years later, the United States was the top steel producer in the world, at over twenty-four million tons annually. As production increased to match the overwhelming demand, the price of steel dropped by over 80 percent. When quality steel became cheaper and more readily available, other industries relied upon it more heavily as a key to their growth and development, including construction and, later, the automotive industry. As a result, the steel industry rapidly became the cornerstone of the American economy, remaining the primary indicator of industrial growth and stability through the end of World War II.

Advancements in communications matched the pace of growth seen in industry and home life. Communication technologies were changing quickly, and they brought with them new ways for information to travel. In 1858, British and American crews laid the first transatlantic cable lines, enabling messages to pass between the United States and Europe in a matter of hours, rather than waiting the few weeks it could take for a letter to arrive by steamship. Although these initial cables worked for barely a month, they generated great interest in developing a more efficient telecommunications industry. Within twenty years, over 100,000 miles of cable crisscrossed the ocean floors, connecting all the continents. Domestically, Western Union, which controlled 80 percent of the country’s telegraph lines, operated nearly 200,000 miles of telegraph routes from coast to coast. In short, people were connected like never before, able to relay messages in minutes and hours rather than days and weeks.
