Speaking of precocious pioneers, Michael Kevin Kearney is as advanced as it gets. Born in 1984, he spoke his first words at only four months, with full sentences at six months. At age 4, he earned a perfect score on multiple diagnostic tests for an advanced mathematics program at John Hopkins University. Despite an ADHD diagnosis, the child prodigy graduated from high school at age 6 and from college at only 10.
His younger sister, Maeghan, was also extremely bright, graduating from college at 16. While it’s difficult to conclusively pick the smartest baby, it’s safe to say Michael Kearney is right up there with the best of them. The same can be said for Elsie Tan-Roberts — the first 2-year-old to be accepted to the renowned high IQ fraternity, Mensa. Her IQ is estimated to be 156, only four points lower than Einstein’s!
