Fred Schwed, Jr., was a professional trader who had the good sense to get out after losing a bundle (of mostly his own money) in the 1929 crash. Some years later, Schwed published a children's book titled Wacky, the Small Boy. Wacky became a bestseller, and Schwed went on to draw further on his experience in writing Where Are the Customers' Yachts? His publisher said of him, "Mr. Schwed has attended Lawrenceville and Princeton and has spent the last ten years on Wall Street. As a result, he knows everything there is to know about children."
