In America in the Gilded Age, Sean Dennis Cashman writes that Edison, along with Alexander Graham Bell, “were, perhaps, the only authentic heroes of the age." Then Cashman adds a little more color to the story, including a few items about Edison that were new to me:
1. Edison had a healthy ego. The American humor magazine Puck wrote: “Edison is the type of man common enough in this country—a smart, persevering, sanguine, ignorant show-off American. He can do a great deal and he thinks he can do everything.”
2. Edison knew what he didn't know. His first notable invention was the Edison Universal Stock Printer (1871), an automatic machine capable of transmitting 200-300 words per minute and far superior to any in use. With the backing of investors, the 24-year-old set himself up as an independent maker of stock tickers in Newark, New Jersey. Then he hired English immigrant Charles Batchelor and Swiss immigrant John Kruesi, both of whom had the scientific training Edison lacked. Edison would conceive, Batchelor would draw, and Kruesi would model.
3. In 1873 Edison devised the diplex and quadruplex, allowing two signals to be sent in each direction on the same telegraph line. The quadruplex was sold to entrepreneur Jay Gould, but it was the court battle over the invention, between Western Union and its rival, Atlantic and Pacific, that made Edison famous.
4. In 1876 Edison established the world’s first industrial research lab at Menlo Park, a prototype for company labs of the future. That year he worked on the electromotograph, acoustic telegraph, autographic telegraph, speaking telegraph, electric pen, mimeograph, electrical dental drill and electric sewing machine. In 1887 he established a research facility ten-times bigger in West Orange, New Jersey, employing 120 research assistants and surrounded by 5,000 people making goods from his inventions.
5. Edison invented the phonograph in 1877. He tested it with racy rhymes like:
Mary has a new sheath gown,
It is too tight by half.
Who cares a damn for Mary’s lamb,
When they can see her calf!
When the new invention was presented in Washington, President Rutherford B. Hayes woke his wife in the middle of the night so that she could hear it.
6. John Pierpont Morgan and other New York financiers subsidized Edison’s newly-formed Edison Electric Light Company, believing he could improve on the electric arc lamp, which used enormous amounts of power. Edison discovered that carbon remained stable in a vacuum; Charles Batchelor thought to shape the wire like a horseshoe, and the first viable incandescent lamp burned for sixteen hours on November 17, 1879. To gain support, Edison worked to get his light accepted in New York, Paris, and London. By 1883 Edison had 246 plants making electricity for 61,000 lamps.
7. Edison was a better inventor than entrepreneur, making and losing several fortunes. He trusted nobody, and his ruthlessness was so ill concealed that he was forced out of his own company. In 1892, when the General Edison Electric Company merged with its great rival, Thomas-Houston, it became General Electric. It took on a new president, Charles Coffin, and it excluded Edison’s name from the company’s title.
