About him
https://www.chicagotribune.com/news/ct-xpm-1995-11-26-9511260313-story.html
“At nine months, Finley walked 30 feet across the floor. By 2, he taught himself to read and, 10 months later, could tell time even with his pocket watch upside down.
Finley wrote a 100-page book at age 5, the same year he took a Stanford-Binet intelligence quotient test. When his 168 score was challenged, he took it again and earned 197 on another test, the second highest IQ ever recorded in the country at that time.”
