One of the first in the business of self-development, the origins of Nightingale Conant stretch back to World War II. Earl Nightingale was a serviceman assigned to the USS Arizona—and was one of only 100 to survive the attack on Pearl Harbor. Convinced he had been spared for a reason, Earl became obsessed with the secret of success. Why would one person find wealth and prosperity, another remain uneducated and penniless, and still another pay for everything in nickels? Late one night in 1956, Earl was struck with an idea, and woke up to write down what would become his biggest success: The Strangest Secret. In 1960, fellow WWII veteran Lloyd Conant joined forces with Nightingale, and the two formed Nightingale Conant, a global enterprise dedicated to disseminating positive psychology through radio, books, and now, the internet.
