Edison Electric Light Co.

In 1878, Thomas Edison established the Edison Electric Light Company in N.Y. City with a syndicate of leading financiers, including J.P. Morgan and the Vanderbilts, who advanced him $30,000 for research and development. Edison proposed to connect his lights in a parallel circuit by subdividing the current, so that, unlike arc lights, which were connected in a series circuit, the failure of one light bulb would not cause a whole circuit to fail. He patented his electricity distribution system in 1880. The first investor-owned electric utility, Pearl Street Station, New York City, (1882) provided service for the 400 lamps of 85 customers. This company and its technological heritage became a part of General Electric in 1892.

Bill, Jim, and Scott were at a convention together and were sharing a large suite on the top of a 75-story skyscraper. After a long day of meetings they were shocked to hear that the elevators in their hotel were broken and they would have to climb 75 flights of stairs to get to their room. Bill said to Jim and Scott, let's break the monotony of this unpleasant task by concentrating on something interesting. I'll tell jokes for 25 flights, and Jim can sing songs for 25 flights, and Scott can tell sad stories the rest of the way. At the 26th floor Bill stopped telling jokes and Jim began to sing. At the 51st floor Jim stopped singing and Scott began to tell sad stories. "I will tell my saddest story first," he said. "I left the room key in the car!"
