It can arguably be said that harnessing the electron has been one of humankind’s crowning achievements.

• For thousands of years, people—including those who have sailed the seas—have been fascinated by lightning, static electricity, and harnessing light. Early humans must have wondered how to put that kind of power to practical use. But it wasn’t until the close of the 18th century that the path to everyday use of electrical power would begin to have a profound and lasting impact the world over, including at sea.
• We all know about Benjamin Franklin, who in 1752 proved that lightning was electrical when he flew a kite during a thunderstorm. He tied a metal key onto the string and, as he suspected it would, electricity from the storm clouds flowed down the string, which was wet, and he received an electrical shock. Maybe not the smartest of ideas, but it sure brought the point home fast!
• Throughout the next hundred years, many inventors and scientists tried to find a way to use electrical power to make light. In 1879, Thomas Edison was finally able to produce a reliable, long-lasting electric light bulb in his laboratory. From that point forward, the world would witness profound technological advances.
• By the end of the 1880s, small electrical stations based on Edison’s designs were springing up in a number of U.S. cities. But each station was able to power only a few city blocks. Elementary electrical systems were beginning to find their way onto ships, and onto pleasure craft reserved for the affluent few. During those early days, electrical safety standards were virtually nonexistent, both on land and at sea.
• Although the majority of people living in larger towns and cities had electricity by 1930, only 10 percent of Americans who lived on farms and in rural areas had electric power. But that was about to change rapidly through the 1940s and 1950s as America was thrust onto the world stage fighting a second world war, the Korean conflict, and the Cold War.
