Wiltshire was born in 1974 in London to West Indian parents. He is an autistic savant and world famous architectural artist. He learned to speak at the age of nine, and at the age of ten began drawing detailed sketches of London landmarks. While he has created many prodigious works of art, his most recent was a eighteen foot wide panoramic landscape of the skyline of New York City, after only viewing it once during a twenty minute helicopter ride.
He has a particular talent for drawing lifelike, accurate representations of cities, sometimes after having only observed them briefly.
