Two year old with the brain of Einstein. Oscar Wrigley has an IQ of at least 160 and at two years and five months, is the youngest child to be accepted into Mensa, the international organisation for people with exceptional intelligence. His score is equal to Einstein and acclaimed British scientist Stephen Hawking.
Oscar's parents say their little genius began talking at nine months and by 18 months was reciting the alphabet in the bath.
By the time he turned two, he had a vocabulary stretching to thousands of words, while most children his age would have mastered only about 50.
Now Oscar lectures his amazed mum and dad about the reproductive cycle of penguins and conducts classical music symphonies as he listens, identifying individual instruments.
"Oscar is a child of very superior intelligence," said Dr Peter Congdon, from the Gifted Children's Information Centre in London.
"His abilities fall well within the range sometimes referred to as intellectually gifted. He demonstrated outstanding ability."
Dr Congdon ranked the toddler in the 99.99th percentile, meaning he is one in 100,000 in terms of his intelligence.
Oscar lives with his IT specialist dad and stay-at-home mum Hannah, 26, in Reading, England.
Both parents have normal IQs, although Oscar's maternal uncle, Jonathan Masters, was a child prodigy who began a university degree in computing aged just 13.
"He is always asking questions," Joe said. "Every parent likes to think their child is special, but we always knew there was something particularly remarkable about Oscar."
Assessors at the Gifted Children's Information Centre said Oscar, an only child, is one of the brightest youngsters they have come across.His intelligence is literally off the scale, with the 45-minute Stanford-Binet test being unable to measure higher than 160.
He will need to be tested further in the years to come to establish his exact score.
He is already showing a gift for music and has asked for a saxophone for Christmas, despite the fact he is far too small to be able to play.
"He will sit in the back of the car listening to the Indiana Jones soundtrack and he'll be conducting with his fingers," Joe said."Then he'll say, 'Here comes the brass with the French horn' and then 'Here come the strings'."
"His vocabulary is amazing. He's able to construct complex sentences. The other day he said to me, 'Mummy, sausages are like a party in my mouth'."A spokesman for Mensa confirmed he was the youngest boy to join the society, which requires a minimum IQ of 148.Mensa UK chief executive John Stevenage said: "Oscar shows great potential. Converting that potential to achievement is the challenge for his parents and we are delighted that they have chosen to join the Mensa network for support."
