In 1970, a Harvard vision scientist named Charles Stromeyer III published a landmark paper in Nature about a Harvard student named Elizabeth, who could perform an astonishing feat. Stromeyer showed Elizabeth’s right eye a pattern of 10,000 random dots, and a day later, he showed her left eye another dot pattern. She mentally fused the two images to form a random-dot stereogram and then saw a three-dimensional image floating above the surface. Elizabeth seemed to offer the first conclusive proof that photographic memory is possible. But then in a soap-opera twist, Stromeyer married her, and she was never tested again.
