Library of Congress This photograph, though from a later Edison lab, shows the heavy machinery in use at Menlo Park. Library of Congress Charles Batchelor These assistants are technicians who had worked for him in New York and New Jersey before the move to Menlo Park. They have a variety of skills. One of them deserves special mention: Charles Batchelor, a bit more than a year older than Edison, immigrated from England a few years earlier to help a company install large textile machines. That says a lot: Weaving technology is very complex.

Making a last-minute bid for this invention would be nothing compared to what Gould has done in the past few years. Using his position as head of the Erie Railroad Company, he manipulated the stock price to make huge profits. About five years earlier, he and some partners caused a panic in the financial markets with an audacious scheme to manipulate the price of gold. They profited, but many speculators were ruined. Even in modern times it’s considered one of Wall Street’s biggest scandals ever.

Now almost twenty-two, he has something even bigger planned. ROAD WARRIOR After Edison saved the young son of James MacKenzie, the grateful father made good on his promise to teach Edison telegraphy and Morse code. Then the telegraph operator at the Port Huron Station left to join the Union Army, and Edison was given a part-time position to replace him. It was the first of a series of jobs all over North America: Stratford Junction, Ontario, Canada; Adrian, Michigan; Fort Wayne, Indiana; Indianapolis, Indiana; Cincinnati, Ohio; Memphis, Tennessee; Louisville, Kentucky; New Orleans, Louisiana; and Boston, Massachusetts.
