Adam Kirby
Adam Kirby’s parents knew he was brighter than most other children when, at 23 months, he potty trained himself after reading a book on the subject.
So advanced was he for his age, that Dean and Kerry-Ann Kirby took their firstborn to get his IQ tested at just two years old. The London native was found to have a score of 141 – higher than many U.S. presidents – despite not even being old enough to fully communicate. He was then invited to join Mensa, where he became the high IQ society’s youngest boy at two years and five months.
