While a graduate student at the University of Iowa in 1939, Mary Tudor assisted in a psychological experiment in which she warned them whenever they were showing signs of stuttering and lectured them whenever they repeated a word, all in an effort to prove that a diagnosis can sometimes cause the condition it seeks to diagnose.
Sixty years later, when Tudor was 84, she received a letter from one of the orphans. It was addressed to “Mary Tudor Jacobs The Monster.”
“You destroyed my life,” it ran. “I could have been a scientist, archaeologist or even president. Instead I became a pitiful stutterer. The kids made fun of me, my grades fell off, I felt stupid. Clear into my adulthood, I still want to avoid people to this day.”
“I didn’t like what I was doing to those children,” Tudor told the San Jose Mercury News in 2001. “It was a hard, terrible thing. Today, I probably would have challenged it. Back then you did what you were told. It was an assignment. And I did it.”
