Many of us know that Thomas Alva Edison was the inventor of the incandescent lamp, phonograph and one of the earliest movie cameras. Some of us who studied the Wizard from Menlo Park during our school days might remember that although he was deaf from age 12 and had very little formal schooling, he became one of the most prodigious inventors in the history of the world, holding patents for more than 1,000 inventions.

It's mind-boggling to think that one person could have invented the incandescent lamp, phonograph, an early motion picture camera — as well as 1,090 other inventions. The modern-day equivalent would be one person inventing the personal computer, cell phone and DVD player.

But the work ethic that Edison employed to develop these inventions and the marketing savvy that he used to promote them are equally impressive. Edison's 20-hour days in the lab are legendary, but I think two of his quotations can inspire us even more. In describing the mistakes and frustrations of his year-long search for the right filament for his incandescent lamp, he said, “If I find 10,000 ways that do not work, I have not failed. I am not discouraged, because every wrong attempt discarded is just one more step forward.”

And while Edison was by any measure a mechanical genius, he attributed much of his success to what he called “stick-to-it-iv-ness”:

“Genius is one percent inspiration and 99% perspiration. As a result, a genius is often a talented person who has simply done all of his homework.”

The man was also a master marketer. Edison invented things, but he also realized that to make money, he had to sell them, too. During his early days as a telegraph operator, he met many of the journalists who filed their stories over the telegraph at the Western Union telegraph office where he worked, and he learned what was news to them. He encouraged reporters to visit his New Jersey lab and was always ready with a good quote.

After inventing the incandescent lamp in 1879, he realized the lamp would be nothing without large-scale power systems to bring electric lighting to the masses. To light the offices of the most influential financiers of his time, he built the first commercial electric generating system in Manhattan in 1880 to power a mile-square area that included the home of the New York Stock Exchange, the nation's largest newspapers and the business of J.P. Morgan, an early investor in his company.

A PBS documentary on Edison said that to create demand for his electric system, he launched a publicity campaign worthy of P.T. Barnum. Edison had 400 men parade through Manhattan wearing light bulbs on their heads. Power lines ran down each man's sleeve to a horse-drawn, steam-powered generator.

All contractors can learn from Edison's marketing campaigns, as well as his work ethic. Whether you are one of the industry's founding fathers or the president of a family-owned contracting business, it doesn't matter how much of a technical wizard you are. You still have to market your products or services.
