One of the biggest inventions in history was the invention of the light bulb by Thomas Edison. He perfected the incandescent light bulb. This is a light bulb that gives off visible light produced by heat. He also came up with the system to produce and distribute electrical power. George Westinghouse another inventor helped Edison come up with other other innovations to make electricity more efficient and safe. This meant the price went down too. Controlling electricity completely changed the way businesses worked now in America. By 1890 electricity ran many different machines. Like the fan and the Printing press as well as many other machines. eventually electricity was available in homes as well.Having light changed all kinds of things. Like people could work later into the night if they wanted. And electricity made everything in factories go a lot quicker because everything was starting to do the work on its on. This speed processing up which meant things would be shipped quicker which meant there would be more income. Street cars were also invented which made public traveling cheap and quick efficient. this also promoted an outward spread of towns and cities.There was more inventions besides the light bulb. Like later on the type writer was invented and the telephone. People liked the type writer because they were probably getting tired of writing things. This machine solved that problem.The telephone changed many things to. The first transcontinental railroad made the world seem pretty small and the telephone made it seem even smaller. Even though it was pretty local at first it eventually spread. This mad communication A LOT easier. Instead of having to travel to talk to people we could now call them and have a conversation on the telephone.All these inventions helped increase the number of women in the office work force. In 1870 women only made up 5% of the work force and in 1910 40% of the office work force was taken up by women. With all of these inventions less humans were needed to work so the average work week was cut down to 10 hours.Some people felt that with all the new machines human labors worth was going to go down which meant some people wouldnt make the money they needed to make in order to support their families.
