The best-known educator of the 20th century was a scammer in cashmere. "The most famous reading teacher in the world," as television hosts introduced her, Evelyn Wood had little classroom experience, no degrees in reading instruction, and a background that included work at a Mormon mission in Germany at a time when the church was cooperating with the Third Reich. Nevertheless, a nation spooked by Sputnik and panicked by paperwork eagerly embraced her promises of a speed-reading revolution. Journalists, lawmakers, and two US presidents lent credibility to Wood's claims of turbocharging reading speeds through a method once compared to the miracle at Lourdes. Time magazine reported that Wood grads could polish off Dr. Zhivago in an hour; a senator swore that Wood's method had boosted his reading speed to more than ten thousand words per minute. But science showed that her method taught only skimming, with disastrous effects on comprehension -- a fact Wood was aware of from early in her career. Fudging test results and squelching critics, she founded a company that enrolled half a million. The course's popularity endured even as evidence of its shortcomings continued to accumulate. Today, as apps and online courses attempt to spark a speed-reading revival, this engaging look at Wood's rise from mission worker to marketer exposes the pitfalls of embracing a con artist's worthless solution to an imaginary problem.
