Generation gap?

During one "generation gap" quarrel with his parents young Michael cried, "I want excitement, adventure, money, and beautiful women. I'll never find it here at home, so I'm leaving. Don't try and stop me!"

With that he headed toward the door. His father rose and followed close behind.

"Didn't you hear what I said? I don't want you to try and stop me."

"Who's trying to stop you?" replied his father. "If you wait a minute, I'll go with you."

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.
