Thomas Edison's laboratory was in Menlo Park, New Jersey. His many inventions made him a great success. However, he did not do it alone. He had many helpers that worked with him all day in the laboratory. Some members of the group included Charles Batchelor, John Kruet, Ludwig Boehm, and Francis Upton.

Edison didn't come up with the idea of the electric light. Others had experimented with it before him, but none of them could get it right. He was convinced by others to

Edison, like many other scientists at the time became interested in a new idea. Alternate Current. He believed that AC Power could majorly harm the human body. He was asked by the New York City Correctional institution to design an electric chair. At first, he refused, but later he decided he would build it using alternate current. Edison believed that a human would die after 5 seconds of the current running through his body. However, it took not 5 seconds but 4 minutes before the man died. That particular occurrence with electrical power was considered a failure.

start working with the electric light. When he did get started, it wasn't just a quick process and all of a sudden he had a light bulb like the ones we use today. It was a slow gradual process before Edison was able to perfect his light. The problem with other electric lights was that they didn't burn long enough and they were too big. One thing that had
